Adnexal torsion as a complication of superovulation for ovum retrieval.

Adnexal torsion has not been reported previously following hMG/hCG for superovulation induction during an IVF cycle. It is clear that the enlarged ovary from the superstimulation cycle and coital activity contributed to the torsion in this case. Portable ultrasonography helped in making the diagnosis and may be an aid for diagnosis in future cases. Medications used for ovulation induction should be used cautiously and judiciously with close monitoring. Clinicians involved with this type of therapy are obligated to keep a constant watch for such infrequent but devastating complications.

Evaluation of adnexal masses in adolescents.

The detection of adnexal masses in adolescents is worrisome to patients, their families, and physicians. Reassurance can be given that the vast majority of these lesions are benign. Furthermore, a significant fraction of benign masses are functional ovarian cysts, most of which resolve spontaneously and never need surgery. Imaging is critical in determining the management of these patients. Sonography is the preferred first-line diagnostic tool. When surgery is necessary, physicians must recognize the importance of conserving the ovaries and uterus to avoid the loss of reproductive and endocrine function.

Detection and characterization of adnexal masses.

The main challenge to the radiologist is to differentiate benign from malignant adnexal masses. Both US and MRI perform well for prediction of benignity. There is less specificity for diagnosis of malignancy but features, such as papillary projections, thickened septations, and internal vascularity within nodules, aid in this differentiation. The combination of morphology and Doppler characteristics provide the most accurate US diagnosis. For sonographically indeterminate masses, MRI is useful for additional lesion characterization. Analysis of T1- and T2-weighted signal intensities for benign-appearing lesions with the addition of fat saturation for high signal on T1-weighted sequences may lead to an exact diagnosis or a narrow differential. For cases considered suspicious by TVUS, more specific diagnosis by MRI may obviate the need for surgery or otherwise change management by identification of benign etiology.

Laparoscopic adnexal preservation in a patient with complete torsion--a case report.

OBJECTIVE: Laparoscopic adnexal preservation in a patient with complete torsion. STUDY DESIGN: Laparoscopy was performed in a 20-year-old nulliparous patient with a 24-h history of lower abdominal pain. RESULTS: Torsion of the left adnexa was diagnosed and detorsion was performed. After detorsion the patient reported complete resolution of pain. At second look laparoscopy blood supply of the left adnexa was completely normalized and a cystadenofibroma was excised with preservation of the ovary. CONCLUSIONS: Complete torsion of adnexa associated with edema and ischemia can be treated by laparoscopic detorsion.

Adnexal mass evaluation in the emergency department.

Female patients who have stable vital signs presenting to the emergency department with abdominopelvic pain and an adnexal mass can be extremely difficult to manage. However, by performing a rapid problem-oriented history and physical with emphasis on the age of patient, menstrual history, and pelvic exam, a detailed differential diagnosis can be compiled. With the addition of a complete blood count and HCG, if appropriate, and a CA-125 for your consultant, additional information can be obtained while a ultrasound examination is being performed. With the above information, consultation and disposition should be readily accomplished.

Approaching the adnexal mass in the new millennium.

Adnexal masses are common dilemmas faced by practicing gynecologists. They affect women from before birth throughout life, yet considerable disagreement exists regarding their optimal management. Traditional management focused on avoiding undertreatment of a potentially malignant process. Advances in detection, diagnosis, and minimally invasive management make it necessary to review this practice to avoid unnecessary morbidity and mortality. The literature emphasizes a minimally invasive approach to the treatment of benign lesions without sacrificing the principles of oncologic surgery.

Adnexal torsion with a paraovarian cyst in a teenage girl.

Adnexal torsion with a paraovarian cyst in adolescent or premenarchal girls is extremely rare and very difficult to diagnose before surgery. We identified three published cases of the disorder in adolescent or premenarchal girls. Our patient, a 12.5-year-old girl, is the fourth. The cyst was excised and the adnexa untwisted at laparoscopy. High awareness and timely laparoscopy contributed to conservation of the adnexa in our young patient.

Apoptosis in fimbriae of fallopian tubes and endometrium in pyoinflammatory adnexal diseases.

In patients with pyoinflammatory adnexal diseases moderate or intense DNA degradation was observed in the majority of epithelial, stromal, and inflammatory infiltration cell in inflammatory foci in the fimbrial compartment of fallopian tubes without signs of tissue destruction. Expression of TNFR1 gene increased 2.7-fold and expression of Fas gene decreased 3.1-fold compared to intact endosalpinx, which indicates induction of apoptosis triggered by tumor necrosis factor-alpha and inhibition of the Fas-dependent pathway. No signs of apoptosis were detected in the endometrium. Generalized apoptosis in the fimbrial compartment of the tubes can be a mechanism limiting the inflammatory process.

Location and intensity of IL-8 and TGF-beta2 mRNA production in the fimbrial compartment of fallopian tubes and IL-10 in the endometrium in patients with pyoinflammatory adnexal diseases.

The location and level of IL-8 and TGF-beta2 expression in the fimbrial compartment of fallopian tubes and IL-10 expression in the endometrium of women with pyoinflammatory adnexal diseases were studied by in situ hybridization. These diseases are associated with considerable changes in the levels of local production of these cytokines. Inflammatory infiltration and epithelial cells were most active producers of IL-9 and TGF-beta2 in the fimbrial compartment of fallopian tubes, while in the endometrium IL-10 gene was expressed at a high level primarily in the glandular epithelial cells.

Female adnexal tumours of probable Wolffian origin: an immunohistochemical study comparing tumours, mesonephric remnants and paramesonephric derivatives.

AIMS: To establish an immunohistochemical profile of presumed female adnexal mesonephric tumours (FATWO) for diagnostic purposes and to compare the findings with those of mesonephric and paramesonephric derivatives in order to establish supportive evidence for a mesonephric origin. METHODS AND RESULTS: Standard immunohistochemistry was performed on formalin-fixed tissues. Tumours, mesonephric remnants and paramesonephric structures generally show positive staining for vimentin, CAM 5.2 and cytokeratins 7 and 19 but are negative for CK20 and 34 beta E12. EMA is positive in both mesonephric and paramesonephric derivatives but is negative in the tumours. Glutathione S-transferase mu (GST mu) is generally positive in both tumours and mesonephric derivatives but negative in paramesonephric structures. CONCLUSIONS: Immunohistochemistry plays little part in the diagnosis of FATWO. The tumours are generally cytokeratin and vimentin-positive and EMA-negative. GST mu, as a marker for the mesonephric duct, is a useful adjunct. Our findings of the study support but do not prove that FATWOs are of mesonephric origin.

Warty dyskeratoma--"follicular dyskeratoma": analysis of clinicopathologic features of a distinctive follicular adnexal neoplasm.

BACKGROUND: The clinicopathologic spectrum of warty dyskeratoma (WD) is not well characterized and the pathogenesis of this unusual lesion is still unclear. OBJECTIVE: We reviewed the clinical and histopathologic spectrum of WD and investigated a possible involvement of human papillomavirus (HPV) infection in onset of this lesion. METHODS: A total of 46 cases of WD were analyzed clinically and histopathologically. Polymerase chain reaction (PCR) analysis for HPV-DNA was performed in 13 lesions of WD. RESULTS: A total of 46 lesions of WD from 45 patients (M/F ratio, 1:1.8; mean age 59.8 years, median 61 years, age range 3-88 years) presented as solitary papules or small nodules on the head and neck (32 cases), trunk (9 cases), lower extremities (4 cases), and upper extremities (1 case). One patient had 2 lesions. No patient had clinical signs of Darier's or Grover's disease. Histopathologically on scanning magnification, lesions showed mainly 3 architectural patterns, namely, cup-shaped (29 cases), cystic (6 cases), and nodular (2 cases). In 9 cases, a combination of two of these morphologic patterns was observed. Characteristically, the epithelial component in all WDs displayed foci of acantholytic dyskeratosis. Variable features suggestive of follicular differentiation toward the infundibular portion of a normal hair follicle were also observed, including a focal contiguity to pilosebaceous units in most cases (63%), and the presence of small infundibular cystic structures in a subset of lesions (46%). The majority of lesions (83%) also revealed a hyalinized or fibrous stroma with intrastromal clefts. PCR analysis for HPV-DNA performed in 13 cases inclusive of all representative architectural patterns was negative. CONCLUSION: We conclude that WD shows a wider spectrum of morphologic features than previously recognized. Despite some histopathologic similarities to viral warts, WD is not a manifestation of HPV infection. On the other hand, the majority of these lesions display overall histopathologic features consistent with a follicular adnexal neoplasm. On the basis of this finding, we propose the alternative term follicular dyskeratoma to better reflect the distinctive features of this peculiar lesion.

Female adnexal tumor of probable Wolffian origin diagnosed during the staging evaluation of extranodal diffuse large B-cell lymphoma.

Female adnexal tumor of probable Wolffian origin (FATPWO) is a rare neoplasm arising within the leaves of broad ligament or hanging from it or a fallopian tube. A 55-year-old female patient with the diagnosis of non-Hodgkin lymphoma is presented. The staging procedure revealed a pelvic mass that was not regressed by chemotherapy. Explorative laparotomy showed FATPWO. The extremely rare coexistence of FATPWO in the staging evaluation of non-Hodgkin lymphoma is reported. According to our knowledge, this is the first case of FATPWO coexisting with extranodal diffuse large B-cell lymphoma in the English-language literature.

Primary cutaneous neuroendocrine carcinoma (Merkel cell tumor). An adnexal epithelial neoplasm.

We report 18 cases of primary cutaneous neuroendocrine carcinoma (CNEC, Merkel cell tumor) that occurred mainly in the sun-exposed skin of elderly patients as dermal and subcutaneous masses of generally monomorphic cells with foci of pronounced pleomorphism. All 18 cases showed immunoreactivity for neuron-specific enolase (NSE), whereas 16 of them showed immunoreactivity for another neuroendocrine marker, protein gene product 9.5 (PGP 9.5). Positivity for PGP 9.5 was more intense and more sharply localized to tumor cells than the staining for NSE. Immunoreactivity for keratins detected by AE1/AE3 and CAM 5.2 monoclonal antibodies was found in 16 and 15 cases, respectively, with prominent paranuclear globular staining. One case stained positively for S-100 protein; all were negative for leukocyte common antigen (LCA). Typical ultrastructural features of neuroendocrine differentiation were noted in all of 14 tumors examined. Morphological and immunohistochemical similarities between these neoplasms and pulmonary small-cell anaplastic carcinoma, now thought to be of bronchial basal cell origin, suggest that CNEC are also derived from epithelium. In addition, their dermal location suggests that this epithelium is likely to be adnexal rather than epidermal.

Basal cell carcinoma with thickened basement membrane: a variant that resembles some benign adnexal neoplasms.

Because cutaneous basal cell carcinoma (BCC) is such a common malignancy, its unusual histologic manifestations are important. We identified a variant of BCC in which thickened basement membranes surround aggregations of neoplastic epithelial cells. Thickened basement membranes of similar appearance have previously been observed in benign cutaneous adnexal neoplasms, in basaloid monomorphic adenomas of the salivary gland and in other benign conditions, such as folliculocentric basaloid proliferation. We identified nine BCCs that otherwise met standard criteria, but which also had thick basement membranes surrounding some of the aggregations, and examined them by routine and histochemical staining. The cases included BCC with nodular, micronodular, and infiltrating patterns. Two neoplasms were composed largely of clear cells, suggesting, together with the thickened membranes, outer root sheath differentiation. CD34, which labels keratinocytes of the outer root sheath, marked only the epithelial cells of one of these cases. The thickened membranes were stained by periodic-acid Schiff with and without diastase (PAS-D) and by antibodies to type IV collagen and laminin, with slightly different staining patterns. Intraepithelial droplets within aggregations stained with PAS-D and type IV collagen antibodies. Thickened basement membranes therefore can occur in most of the common growth patterns of BCC. The absence of CD34 staining of epithelial cells in most cases makes it problematic at this time to prove that the thickened membranes indicate trichilemmal differentiation. BCC with thick basement membranes can closely mimic benign neoplasms, such as cylindroma and trichilemmoma, from which they can be distinguished in routinely stained sections. The presence of a continuous thick basement membrane around aggregates of epithelial cells does not in and of itself distinguish between benign and malignant cutaneous epithelial neoplasms.

Aggressive papillary tumor of middle ear/temporal bone and adnexal papillary cystadenoma. Manifestations of von Hippel-Lindau disease.

The occurrence of an aggressive papillary middle ear/temporal bone tumor (APMET) and a benign adnexal papillary tumor of probable mesonephric origin (APMO) in a patient with von Hippel-Lindau disease (VHL) is reported. Histologically, both tumors were identical to papillary cystadenomas of the epididymis and broad ligament of probable mesonephric derivation. A comprehensive literature review showed that including the current case, seven of 46 (15%) documented cases of APMET and four of four (100%) cases of APMO arose in patients with VHL. Given an estimated minimum birth incidence of 1/36,000, a one-sample test of binomial proportion using the exact method establishes that the association of APMET and APMO with VHL is highly significant (p = 1.4 x 10(-24) and 1 x 10(-18), respectively). The data indicate that APMET and APMO may represent major visceral manifestations of VHL. Accordingly, in the presence of one of these tumors strong consideration should be given to the diagnosis of VHL, given either the presence of another major component of VHL or documentation of VHL in at least one consanguineous relative.

Adnexal torsion.

This review provides timely information concerning clinical, surgical, and pathologic findings of adnexal torsion (AT). AT mostly occurs in the child-bearing age group, but is not uncommon in premenarchal girls or postmenopausal women. When AT is suspected, urgent surgical intervention is indicated, and is usually performed by laparoscopy. Incidence of AT is 3.5% of all benign cystic teratomas. Despite the "necrotic" appearance of the twisted ischemic ovary, detorsion is the only procedure which should be performed at surgery. Adnexectomy should be avoided as ovarian function is preserved in 88% to 100% of cases. Awareness and suspicion of the diagnosis of AT is needed in patients who present with lower abdominal pain.

Endometrioid carcinoma of the fallopian tube resembling an adnexal tumor of probable wolffian origin: a report of six cases.

Six adenocarcinomas of the fallopian tube that resembled the female adnexal tumor of probable wolffian origin are described. The tumors, which occurred in patients from 38 to 66 (average 55) years of age, typically formed intraluminal masses. One was an incidental finding on microscopic examination. On microscopic examination, the tumors were characterized by a predominant pattern of small, closely packed cells punctured by numerous glandular spaces, which were typically small but occasionally were cystically dilated. Many of the glands contained a dense colloid-like secretion that was positive with the periodic acid-Schiff stain. Small amounts of intracellular mucin were present in all cases. In the solid areas of three cases, spindle cells that focally formed concentric whorls were present. In all cases, small numbers of tubular glands typical of endometrioid adenocarcinoma were identified. The cytologic atypia and mitotic activity of the tumors were variable, but they exceeded that usually seen in wolffian duct tumors. The evidence indicates that this neoplasm represents an unusual form of endometrioid adenocarcinoma. It is important that it is distinguished from a tumor of wolffian duct origin.
