Adnexal masses in women with breast cancer: US findings with clinical and histopathologic correlation.

PURPOSE: To correlate ultrasonographic (US), clinical, and histopathologic findings in patients with breast cancer who underwent surgery for adnexal masses evident at US. MATERIALS AND METHODS: A database search yielded 54 patients with breast cancer and with adnexal masses at US and histopathologic examinations. Clinical, US, and histopathologic findings were correlated. RESULTS: Forty (74%) patients had benign adnexal masses, and 14 (26%) had malignant masses; three patients had both benign and malignant ovarian masses. Seven patients had primary ovarian cancer, and seven had breast metastases to the ovary. All breast metastases to the ovary were bilateral solid masses at histopathologic examination and occurred in women with stage IV breast carcinoma at the time of US. Eleven ovaries with breast metastases were solid at US. The remaining three ovaries with breast metastases had cystic components at US because of hemorrhage or coexistent benign ovarian cysts. Four of seven patients with primary ovarian carcinoma had bilateral ovarian tumors, and seven of 11 ovarian carcinomas were predominantly cystic at US. No patient with primary ovarian carcinoma had stage IV breast cancer. CONCLUSION: In this small series, half the ovarian malignancies in patients with breast cancer were primary ovarian carcinomas and half were breast metastases to the ovary. Breast metastases to the ovary most frequently are bilateral solid masses at US and are associated with stage IV disease at the time of US.

Trichogerminoma: a rare cutaneous adnexal tumor with differentiation toward the hair germ epithelium.

In 1992, Sau and colleagues described 14 cases of a rare cutaneous adnexal tumor with differentiation toward the hair germ epithelium. All cases in their study displayed a unique constellation of histological features which allowed the authors to consider the neoplasm to be a distinct entity and to designate it as 'trichogerminoma' (TG). We present a case of an adnexal tumor identical to that described as TG and report the immunophenotypical features of this neoplasm for the first time. A biopsy from a 41-year-old man revealed a well-demarcated epithelial tumor composed of multiple lobules located in the deep dermis without connection to the overlying epidermis and surrounded by a fibrous pseudocapsule. The tumorous lobules were composed of uniform basophilic cells with vesicular nuclei, dispersed chromatin and prominent nucleoli showing no prominent peripheral palisading. Some of the lobules had the appearance of densely packed 'cell balls' with peripheral condensation of the tumor cells. The stroma showed a moderate number of fibroblasts and mast cells. Reticulum staining revealed fine reticulum fibers surrounding the tumor aggregates with accentuation of the 'cell balls'. Immunohistochemically, the tumor cells expressed AE1/AE3, CK5/8, CK5/6, CAM5.2 and stained negatively for CK20, CK7, calretinin, Lu-5 and Thomsen- Friedensreich antigen. There was no increase in the numbers of CK20-positive Merkel cells in the epidermis overlying the tumor; however, a few Merkel cells were scattered in some tumor lobules. In addition, we stained 6 trichoblastomas (TBs) and found a particular pattern of calretinin expression in this tumor which was not observed in our case of TG. We conclude that pathological features allow the delineation of TG as a distinct adnexal neoplasm. Histological differential diagnosis includes basal-cell carcinoma (pilar type), large nodular TB, trichoblastic fibroma, trichoepithelioma, tricholemmoma, pilomatricoma and matrical carcinoma.

Mucocele of the vermiform appendix with sonographic appearance of an adnexal mass.

Mucocele of the vermiform appendix is caused by mucus retention in its lumen, due to obstruction or hyperproduction. Appendiceal malignancy can be the underlying cause, making accurate preoperative diagnosis imperative. In women, it can sometimes present as an adnexal mass. A rare case of an appendiceal mucocele is presented, mimicking a cystic tumor of the right adnexum, both clinically and ultrasonographically. In addition, serum levels of CA-125 were increased. This is the first case of a mucocele of the appendix simulating an adnexal mass on ultrasound with increased levels of CA-125 to be reported. This clinical entity should be considered in patients presenting on ultrasound with a right-sided adnexal mass as a rare potential diagnosis.

Cutaneous adnexal neoplasms.

Cutaneous adnexal tumors are a large and diverse group of tumors that are commonly classified according to their state of appendageal differentiation: eccrine, apocrine, follicular, and sebaceous. These tumors generally behave in a benign manner, but malignant types exist. Most adnexal tumors are not common enough to permit most practitioners to maintain a ready familiarity with them, but they also are not rare. We provide a brief review of the clinical, histopathologic, and other relevant features of some adnexal tumors we believe the practitioner has the greatest likelihood of seeing in daily service. We also enumerate criteria the practitioner can use to distinguish between tumors likely to behave in a benign rather than a malignant manner.

MRI of sonographically indeterminate adnexal masses.

OBJECTIVE: The purpose of this study was to assess the ability of MRI to characterize sonographically indeterminate adnexal masses and to define the sonographic features contributing to indeterminate diagnoses. MATERIALS AND METHODS: Two blinded radiologists retrospectively reviewed the MRI examinations of 87 patients with 95 sonographically indeterminate adnexal masses. Reviewers determined the origin of a mass, its tissue content (cystic, solid, complex cystic, or cystic and solid), tissue characteristics (fat, blood, fibrous, or leiomyomatous), and benignity versus malignancy. Sonograms were reviewed by three reviewers to determine the origin of a mass, its tissue content, and reasons for an indeterminate diagnosis. Sensitivity and specificity of MRI were calculated, and agreement of sonography and MRI with the final diagnosis was determined using kappa statistics. The final diagnosis was determined by histopathology, surgical findings, or imaging or clinical follow-up. RESULTS: The sensitivity of MRI for identifying malignancy (n = 5) was 100% and its specificity for benignity (n = 90) was 94%. Excellent agreement was seen between MRI and the final diagnosis for determining the origin (kappa = 0.93), tissue content (kappa = 0.98), and tissue characteristics (kappa = 0.91) of a mass. Sonography had poor agreement with the final diagnosis for the origin (kappa = 0.19) and tissue content (kappa = 0.33) of a mass. The main reasons for indeterminate sonographic diagnoses were the inability to determine origin because of location and large mass size and the appearances of purely solid or complex cystic masses. CONCLUSION: Sonographically indeterminate adnexal masses of uncertain origin and solid or complex cystic content benefit from further evaluation with MRI, which is highly accurate for identifying the origin of a mass and characterizing its tissue content, obviating surgery.

Radiological reasoning: imaging characterization of bilateral adnexal masses.

OBJECTIVE: A 46-year-old woman presented with bilateral adnexal masses on pelvic sonography, a complex cystic mass on the right, and a homogeneously hypoechoic, solid-appearing mass on the left. Pelvic MRI showed a T1 hypointense, T2 hyperintense, nonenhancing mass in the right ovary and a homogeneously T1 hyperintense lesion with mixed T2 signal in the left ovary. Fat-saturated T1-weighted sequences showed the left ovarian lesion to be an endometrioma containing a high concentration of hemoglobin breakdown products and revealed other endometriotic implants in the right ovary, broad ligament, and cul-de-sac. Follow-up pelvic sonography 9 weeks later showed resolution of the right complex cystic ovarian mass, indicating that it was a physiologic hemorrhagic cyst. CONCLUSION: Imaging features of benign and malignant ovarian masses overlap. If imaging is inconclusive in characterizing an adnexal mass as benign, the mass will be resected rather than followed up because of the concern for a rapidly growing ovarian cancer. Thus, the goal of imaging is to identify unequivocally the benign lesions that can be left untreated. Pelvic MRI provides a powerful adjunct to pelvic sonography in characterizing adnexal masses as benign.

Transvaginal color Doppler sonography of adnexal masses: differences in blood flow impedance in benign and malignant lesions.

OBJECTIVE: The purpose of this study was to assess the blood flow characteristics of adnexal masses before surgical excision and to determine whether color flow Doppler sonography is useful for distinguishing benign from malignant masses. SUBJECTS AND METHODS: Thirty-one adnexal masses were evaluated with color flow Doppler transvaginal sonography. The pulsatility index and resistive index were calculated from the waveforms generated from blood flow within the ovary. Twenty-five lesions were benign and six were malignant on pathologic examination. Benign lesions included six endometriomas, six mesothelial cysts, three serous and one mucinous cystadenoma, three mature cystic teratomas, two hemorrhagic corpus luteum cysts, one cystadenofibroma, one sclerosing stromal cell tumor, one paratubal cyst, and one ovary that had undergone torsion with infarction. The malignant lesions consisted of three papillary serous cystadenocarcinomas, one granulosatheca cell tumor, one immature teratoma, and one metastasis of colon cancer to the ovaries. RESULTS: Benign tumors and cysts had a significantly higher pulsatility index (mean, 1.93 +/- 1.02; range, 0.23-3.99) and resistive index (mean, 0.77 +/- 0.22; range, 0.2-1.0) than did malignant tumors (pulsatility index: mean, 0.77 +/- 0.33; range, 0.31-1.09; resistive index: mean, 0.5 +/- 0.17; range, 0.27-0.67). However, some overlap in individual values for benign and malignant lesions was found. CONCLUSION: Our preliminary data suggest that high pulsatility and resistive indexes indicate benign adnexal processes; however, considerable overlap in pulsatility and resistive indexes between benign and malignant lesions was noted, and further work is needed before the validity of these factors is proved.

Is differentiation of benign and malignant cystic adnexal masses possible by evaluation of cysts fluids with respect to color, cytology, steroid hormones, and tumor markers?

OBJECTIVE: Differentiation of benign and malignant cystic adnexal masses by analysis of cyst fluid was investigated. STUDY DESIGN: Eighty-one cystic adnexal lesions of 80 patients were punctured intraoperatively or after surgical removal. Color of the cyst fluid, cytology, concentrations of steroid hormones (estradiol, progesterone, testosterone), and tumor markers (CEA, CA 125, CA 15-3) were correlated to histology. RESULTS: Color of cyst fluid was not reliable in the differential diagnosis of cystic adnexal masses. Cytology missed four out of seven malignant tumors. One mucinous cystadenoma was cytologically suspicious for malignancy. The combination of negative cytology, low tumor marker levels, and estradiol levels higher than 1000 pg/ml may support the diagnosis of a 'functional' cyst. Elevated CEA levels may be suspicious for all mucinous and malignant lesions. CONCLUSION: Analysis of cyst fluid could not accurately discriminate between benign or malignant tumors.

Histology according to the Revised European-American Lymphoma Classification significantly predicts the prognosis of ocular adnexal lymphoma.

Lymphoid infiltrates in the ocular adnexa are mostly low-grade B-cell lymphoma, but their clinicopathologic characteristics and prognostic factors have not been extensively analyzed according to the Revised European-American Lymphoma (REAL) Classification. We reviewed histopathologic sections from 77 patients with primary ocular adnexal lymphoid infiltrates, and conducted univariate and multivariate analyses of possible prognostic factors. Fifty-seven of the 77 patients were confirmed to have malignant lymphoma. Histopathologic sections from 44 of the 57 patients were reclassified into the following categories; marginal zone lymphoma (MZL) in 35, mantle cell lymphoma (MCL) in two, diffuse large cell lymphoma (DLCL) in six, and lymphoplasmacytoid lymphoma (LPL) in one. In the remaining 13 patients, biopsied specimens were inadequate for further subclassification. The cause-specific survival rates of the 57 patients with primary ocular adnexal lymphoma at 5, 10, and 15 years were 90.1%, 84.8% and 84.8%, respectively. The univariate analysis showed that the clinical stage, serum lactate dehydrogenase (LDH) value and histopathologic subtype were significant. The 5-year cause-specific survival rate of the 35 patients with MZL was 100%, whereas that of the eight patients with non-MZL (DLCL and MCL) was 25% (p<0.0001). The multivariate analysis revealed that the histologic subtype (p=0.010) and serum LDH value (p=0.015) were independent significant predictors of survival. We conclude that malignant lymphomas occurring in the ocular adnexa histologically consist mostly of MZL. The histologic subtype according to the REAL Classification significantly predicts the prognosis of ocular adnexal lymphoma.

In-vivo proton magnetic resonance spectroscopy in adnexal lesions.

OBJECTIVE: To explore the in-vivo 1H- MR spectral features of adnexal lesions and to characterize the spectral patterns of various pathologic entities. MATERIALS AND METHODS: Thirty-one patients with surgically and histopathologically confirmed adnexal lesions underwent short echo-time STEAM (stimulated echo acquisition method) 1H- MR spectroscopy, and the results obtained were analysed. RESULTS: The methylene present in fatty acid chains gave rise to a lipid peak of 1.3 ppm in the 1H- MR spectra of most malignant tumors and benign teratomas. This same peak was not observed, however, in the spectra of benign ovarian epithelial tumors: in a number of these, a peak of 5.2 ppm, due to the presence of the olefine group (-CH=CH-) was noted. The ratios of lipid peak at 1.3 ppm to water peak (lipid/water ratios) varied between disease groups, and in some benign teratomas was characteristically high. CONCLUSION: An intense lipid peak at 1.3 ppm is observed in malignant ovarian tumors but not in benign epithelial tumors. 1H- MRS may therefore be helpful in the differential diagnosis of adnexal lesions.

The significance of the postmenopausal simple adnexal cyst.

In order to help clarify the clinical problem of the postmenopausal woman with an adnexal cyst, 13 patients with sonographically detected relatively simple adnexal cysts were reviewed. Only one patient had a "borderline" malignancy; the remaining cysts were all benign. The 8 per cent malignancy rate in this small series suggests that the simple postmenopausal adnexal cyst may not necessarily be an ominous finding.

Three-dimensional sonographic morphologic assessment in complex adnexal masses: preliminary experience.

OBJECTIVE: To evaluate the role of three-dimensional transvaginal sonography in assessing complex adnexal masses. METHODS: Forty-one women (mean age, 49.5 years; range, 23-75 years) with the diagnosis of complex adnexal masses on the basis of two-dimensional transvaginal sonography were reevaluated by three-dimensional transvaginal sonography. Two different sonologists evaluated the two- and three-dimensional transvaginal sonograms. Criteria indicative of malignancy included the presence of gross papillary projections, solid areas, and solid echogenicity for both techniques. Three women (7%) had bilateral masses, giving a total of 44 masses that were ultimately assessed. A definitive histologic diagnosis was obtained in every case after surgical tumor removal. RESULTS: Twenty-one tumors (47.7%) were proved malignant, and 23 (52.3%) were benign. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy for two- and three-dimensional transvaginal sonography were 90%, 61%, 68%, 87%, and 75% and 100%, 78%, 81%, 100%, and 89%, respectively. There were no statistical differences between two- and three-dimensional transvaginal sonography (McNemar test, P = .687). The agreement between both examiners was high (kappa index = 0.71). CONCLUSIONS: The use of three-dimensional transvaginal sonography does not significantly improve the two-dimensional transvaginal sonographic morphologic assessment of complex adnexal masses; however, we found it useful for reinforcing initial diagnostic impressions.

Three-dimensional power Doppler vascular sampling: a new method for predicting ovarian cancer in vascularized complex adnexal masses.

OBJECTIVE: The purpose of this study was to explore the role of a new concept ("vascular sampling") as a third step to discriminate benign and malignant lesions in B-mode and color Doppler sonographically suggestive adnexal masses. METHODS: Forty-five women (mean age, 52.3 years; range, 17-82 years) with the diagnosis of complex adnexal masses on B-mode sonography were evaluated using 3-dimensional power Doppler sonography. Four women had bilateral masses. After a morphologic reevaluation was done, color pulsed Doppler sonography was used to obtain flow velocity waveforms, and velocimetric indices were calculated (resistive index, pulsatility index, and peak systolic velocity). Thereafter, 3-dimensional power Doppler sonography was used to assess vascularization of highly suggestive areas (gross papillary projections, solid areas, and thick septations), meaning a focused assessment ("sampling") of a suggestive area of the tumor. With a virtual organ computer-aided analysis program, vascular indices (vascularization index, flow index, and vascular flow index) were automatically calculated. A definitive histologic diagnosis was obtained in each case. RESULTS: Forty masses (82%) were malignant and 9 (18%) were benign. Morphologic evaluation revealed 10 (20%) unilocular solid masses, 20 (41%) multilocular solid masses, and 19 (39%) mostly solid masses. Blood flow was found in all cases. Median vascularization index (15.5% versus 8.2%; P = .002), flow index (33.6 versus 20.8; P = .007), and vascular flow index (5.2 versus 2.3; P = .001) were significantly higher in malignant tumors. No differences were found in resistive index (0.43 versus 0.45; P = .770), pulsatility index (0.62 versus 0.65; P = .694), and peak systolic velocity (15.6 versus 12 cm/s; P = .162). CONCLUSIONS: Three-dimensional power Doppler vascular sampling seems to be a promising tool for predicting ovarian cancer in vascularized complex adnexal masses. It could be better than conventional color pulsed Doppler imaging.

[Surgical approach in cases of adnexal pathology in adolescents and young women].

Retrospective analysis comprised 108 cases of adnexal pathology found at laparotomy in the group of adolescents and young women up to the age of 25. The most common condition necessitating the laparotomy was hemorrhagic corpus luteum (24% of cases). Adnexal cysts of different but benign histological structure had been found in 30.5% of cases. Malignant germ cell tumors (6 cases--dysgerminoma and teratoma immaturum) all of which at Ia stage at the time of laparotomy, had been treated conservatively with unilateral salpingo-oophorectomy. Authors suggest that the conservative approach should be applied in most cases of adolescents' adnexal pathology.

[Experience with laparoscopic surgery for adnexal masses at the Regional Hospital of Temuco, Chile].

BACKGROUND: Laparoscopic surgery has clear advantages over open surgical procedures. In gynecology, laparoscopic surgery for adnexal masses in pre or post menopausal women has been used for several years. AIM: To report the experience with gynecologic laparoscopic surgery at the Temuco Regional Hospital. PATIENTS AND METHODS: Between 1996 and 1998, laparoscopic surgery was done in 96 patients aged 16 to 56 years and open surgery in 56 patients aged 15 to 74 years, with a clinical or ultrasound diagnosis of adnexal masses or ovarian dermoid cysts. RESULTS: The most frequent tumors excised were epithelial and germinal cell. Laparoscopic surgery required a mean operative time of 69.9 min and it had a 3.1% of complications. Women subjected to this type of surgery had a mean hospital stay of 3.1 days and the mean postoperative stay was 2 days. Open surgery required an operative time of 69 min and it had no postoperative complications. The mean hospital stay for women subjected to this type of procedure was 9.5 days. CONCLUSIONS: Women subjected to laparoscopic surgical procedures for adnexal masses had a shorter hospital stay than women subjected to open surgical procedures.

[Ultrasonographic and biochemical screening of adnexal masses before operative laparoscopy].

BACKGROUND: The object of our study was to evaluate how reliable ultrasonographic and biochemical screening of adnexal masses are in the selection of patients eligible for operative laparoscopy. METHODS: The study was performed at the First Clinic of Obstetrics and Gynecology, University of Rome La Sapienza, Italy. Eighty-seven women of 36.8 +/- 12 years of age, who underwent operative laparoscopy between January 1999 and January 2000 to remove an adnexal lesion, were enrolled. These adnexal lesions had been previously diagnosed on the basis of a pelvic ultrasonographic imaging; this was performed because of follow-up procedure or pelvic pain. The lesions were evaluated preoperatively according to Sassone echographic scoring system. The CA-125 level was determined in 58 patients. RESULTS: Surgery was successful in all 87 cases. In one case the operative laparoscopy had to be turned into laparotomy since the histologic examination revealed an atypical proliferative mucinous cystoadenoma. Sassone total average echographic score was 6.0 +/- 1.7; this is below the discriminant cut-off for malignancy (9). The only case in which Sassone score reached 10 was an atypical cystoadenoma. The CA-125 level was higher than 35 IU/ml (cut-off of this marker) in 13.7% of the patients; these were all affected by endometriosis or had a hemorrhagic corpus luteum. In the patient with atypical cystoadenoma, the CA-125 level was within normal range (29.1 UI/ml). The post-operative period was uneventful in all cases but one, in which the occurrence of pulmonary thromboembolism required a prolonged hospitalization. CONCLUSIONS: The use of Sassone echographic scoring system proved to be very useful and effective in the selection of the patients. Tumor markers are relevant factors only if their evaluation is accompanied by an accurate anamnesis and is supported by the findings of abdominal and transvaginal ultrasonography.

[Difficulties in differential diagnosis of adnexal masses during pregnancy: the role of greyscale and color doppler sonography].

We have attempted to determine the accuracy of greyscale and color Doppler ultrasound in the differentiation of adnexal masses in pregnancy. The studied group included 2245 pregnant women from low risk population. Following criteria were evaluated: maximal diameter and volume of the tumor, echogenicity, presence of septa and papillary projections in grey scale sonography. Color Doppler analysis included blood vessel presence and arrangement and blood flow characteristics with the use of pulsatility (PI), resistive (RI) and systolic/diastolic (S/D) indices. Preoperative CA-125 serum levels were available in 11 patients. In 66 (2.94%) patients adnexal tumors were detected during routine ultrasound scan at the end of the first trimester. Twenty-seven masses (1.2%) persisted beyond 16 weeks of gestation and were subsequently surgically removed. Pathological diagnosis confirmed 19 serous cystadenomas, 4 endometriomas and 2 dermoids, one pedunculated myoma and one fibrothecoma. Mean size of the tumors was 79 Jmm (range: 43-245 mm), mean volume 166. lml (range: 30-1320 ml). Doppler indices values presented as mean, SD and range were as follows: PI = 1.26 +/- 0.71 (range: 0.57-3.84); RI = 0.61 +/- 0.15 (range: 0.33-0.89) and S/D = 2.62 +/- 0.98 (range: 1.17-4.91). Median serum concentration of CA-125 was 17 IU/ml (range: 8.4-1247 IU/ml). Only 3 of these women had elevated (> 35 IU/ml) levels: 2 endometriomas (344 IU/ml and 1247 IU/ml) and one myoma (37 IU/ml), respectively. Based on the sonographic findings two solid tumors were incorrectly classified as probably malignant (fibrothecoma and subserous myoma). Negative predictive value of ultrasound diagnosis in the studied population was therefore 92.6% (25 of 27). We conclude that although prenatal sonography has the potential to correctly classify most of adnexal masses, caution in risk assessment is needed especially when persistent solid tumor is found.

Evaluation of adnexal masses by ultrasound and fine needle aspiration cytology.

Forty Eight cases of adnexal masses were subjected to ultrasound and FNAC. In this study, FNAC could differentiate benign and malignant adnexal masses in 98% of cases where as ultrasound was successful in 85% of cases. FNAC is a safe simple, rapid & reliable investigation. The complex adnexal masses present a diagnostic challenge with particular reference to the findings predictive of malignancy.
