Metastatic and independent cancers of the endometrium and ovary: a clinicopathologic study of 34 cases.

Twenty-one of 34 simultaneous cancers involving the endometrium and ovary were classified as endometrial primary tumors with ovarian metastases. The criteria for this classification were either a multinodular ovarian pattern (major criterion) or two or more of the following minor criteria: small (less than 5 cm) ovary(ies), bilateral ovarian involvement, deep myometrial invasion, vascular invasion, and tubal lumen involvement. Twelve cancers were classified as independent neoplasms, primarily by the absence of the above criteria. Although they were classified as independent, the histologic features of the endometrial and ovarian tumors were the same in 11 of these 12 cases. Only one case represented an ovarian primary tumor with an endometrial metastasis. Both the group believed to have endometrial primaries with ovarian metastases and that with independent primaries showed high incidences of associated endometrial hyperplasia, supporting the belief that the endometrium is a primary site in both groups. The cancers classified as metastatic, with no known spread outside the endometrium-myometrium and ovary, were found to involve other sites significantly (P less than 0.01) more frequently than those classified as independent. Grade 3 endometrioid carcinoma, adenosquamous carcinoma, and malignant mixed müllerian tumors occurred only in the metastatic group, whereas the independent group had a variety of endometrioid and nonendometrioid tumors.

An amylase-producing serous cystadenocarcinoma of the ovary.

A patient with an amylase-producing serous cystadenocarcinoma of the ovary had elevated serum and urine amylase levels and high levels of amylase in pleural and ascitic fluids. Serum and urine amylase levels reflected both surgical removal of tumor mass and response to chemotherapy. Tumor homogenates had pronounced amylase activity. Salivary type amylase isozyme patterns were found in electrophoresis of samples from all sources. Ascites tumor cells were successfully cultured and salivary type amylase was found in the culture media throughout 5 passages. The tumor was classified by light microscopy as poorly differentiated serous cystadenocarcinoma. Ultrastructural studies on the tumor were consistent with that diagnosis. Amylase was detected in the cells of the tumor examined by the immunoperoxidase technique.

Common epithelial tumors of the ovary: proliferating and of low malignant potential.

Ovarian tumors of low malignant potential (LMP) must be distinguished from benign, "proliferating" ovarian tumors and from frank ovarian carcinoma. Serous and mucinous tumors of LMP demonstrate epithelial stratification, the formation of epithelial tufts, cytologic atypia, and mitotic activity, but they do not demonstrate stromal invasion by epithelial cells, which is a feature of frank carcinoma. Mucinous carcinoma may also be recognized by epithelial stratification exceeding three cell layers and the formation of true cribriform glandular patterns. Although controversial, we do not at present recognize a LMP tumor of endometrioid type but prefer to classify those endometrioid neoplasms with a prominent fibrous stroma and glandular complexity similar to adenomatous endometrial hyperplasia as proliferating endometrioid adenofibromatous and cystadenofibromatous tumors. There is only mild cytologic atypia in such tumors. Because of the moderate to marked cytologic atypia that occurs in some clear cell neoplasms with a prominent fibrous stroma, we believe those tumors do merit a designation of LMP tumors. In both the proliferating endometrioid and LMP clear cell adenofibromatous and cystadenofibromatous tumors, carcinoma must be excluded by an absence of stromal invasion, which is frequently recognized by a confluent glandular pattern. The histologic features of proliferating Brenner tumors are similar to those of low grade, papillary, noninvasive, urothelial carcinoma, whereas we propose that Brenner tumors of LMP show high grade cytologic atypia but remain noninvasive in the ovary.

The development of non-germ cell malignancies within germ cell tumors. A clinicopathologic study of 11 cases.

Eleven male patients had germ cell tumors of the testis (7), mediastinum (3), or retroperitoneum (1) in which non-germ cell malignancies developed. Such malignant non-germ cell elements were present in the primary excisions of five patients and were subsequently found in additional resected tissue in 10 of 11 patients. In the patients who had multiple pathology specimens examined, a progression from atypia to predominant non-germ cell malignancy was often found. The authors believe these malignant elements arose within teratomatous foci, since eight of nine cases had teratoma in the primary tumor, and teratoma was found in subsequently resected tissue in one additional case. Cisplatin therapy frequently "unmasked" the non-germ cell malignant elements by destroying the more chemosensitive germ cell cancers. The prognosis was worst for five patients who developed progressive embryonal rhabdomyosarcoma: two of these patients died of local spread of tumor, whereas a third died of metastatic sarcoma. Only one patient, who had total surgical excision of rhabdomyosarcoma, survived. Other forms of sarcoma that developed within germ cell tumors did not appear to adversely affect the prognosis beyond that of teratoma. It is currently recommended, when feasible, that patients with teratoma and sarcoma undergo total surgical excision. Further treatment with cisplatin regimens, after eradication of the germ cell component, has not been helpful. The role of other forms of chemotherapy remains speculative.

Ovarian clear cell adenofibromatous tumors. Benign, of low malignant potential, and associated with invasive clear cell carcinoma.

The authors have studied 17 cases of ovarian clear cell tumors having an adenofibromatous pattern and classified them on a histologic basis into three categories: benign, of low malignant potential, and associated with invasive clear cell carcinoma. Clear cell adenofibroma is characterized by orderly tubules and glands lined by uniform epithelium with little or no nuclear atypia set in an abundant stroma with an interlacing pattern resembling ovarian stroma. Clear cell adenofibromatous tumors of low malignant potential had a similar stroma, but exhibited moderate to marked degrees of epithelial proliferation and atypia. In the third category there were cases of invasive clear cell carcinoma in which a distinct portion of the tumor met the criteria for clear cell adenofibroma, or clear cell adenofibromatous tumor of low malignant potential. Cases of invasive clear cell carcinoma exhibiting a desmoplastic reaction or a diffuse fibrous stroma, but lacking typical adenofibromatous areas, were not included in this study. The benign and low malignant potential tumors showed no clinical evidence of aggressive behavior, whereas those associated with invasive clear cell carcinoma often did. Although there have been no recurrences in our small group of patients with tumors of low malignant potential, the histologic similarity of the epithelium in these tumors to that seen in invasive carcinomas justifies such a categorization. Further studies of larger series using the proposed classification should yield more information concerning the biologic behavior of these types of clear cell adenofibromatous tumors.

Secondary ovarian neoplasia. A clinicopathologic study of 35 cases.

The authors reviewed the clinical and pathologic features of 35 cases of secondary ovarian neoplasms in which the clinical presentation was that of a primary ovarian tumor. The most common secondary neoplasms to mimic an ovarian tumor were colonic adenocarcinoma, breast carcinoma, lymphoma, carcinoid, and gastric adenocarcinoma. It was found that a classification based on gross appearance was useful in evaluating these neoplasms. Solid neoplasms with either a diffuse or nodular gross appearance had distinct histologies so that accurate diagnosis was possible. Cystic neoplasms, especially colon adenocarcinomas, were deceptive and frequently misclassified as primary ovarian adenocarcinoma. Since all of the metastatic colonic carcinomas had mucus-containing cells, the main differential diagnosis was between metastatic colonic carcinoma and primary mucinous carcinoma of the ovary. The absence of a mucus-cell predominant pattern and the lack of transition from benign-appearing epithelium to malignant epithelium are two useful criteria in making this important distinction. Other features may also prove helpful.

Lymphomatoid granulomatosis. Successful treatment with CHOP combination chemotherapy.

A patient with lymphomatoid granulomatosis is reported. The patient was treated with a combination of cyclophosphamide, doxorubicin, vincristine, and prednisone as initial management immediately after diagnosis. She obtained a complete remission and remains free of disease 3 1/2 years from the time of diagnosis. The favorable outcome in this patient may be related to her initial limited disease or to the use of initial intensive chemotherapy; nonetheless, the generally unfavorable prognosis of this disease appears to mandate early trials of intensive therapy in most patients.

Epithelioid sarcoma of the vulva. Evidence suggesting a more aggressive behavior than extra-genital epithelioid sarcoma.

The authors describe two cases of epithelioid sarcoma of the vulva and summarize the clinical and pathologic experience with this vulvar neoplasm. Findings indicate that epithelioid sarcoma of the vulva usually occurs in the labia majora of young women, but may occur in later life. Clinically it may mimic a Bartholin's duct cyst, thus leading to inadequate treatment. Pathologic findings are characterized by sheets and nests of acidophilic, polygonal cells. Follow-up study suggests that vulvar epithelioid sarcoma behaves more aggressively than extragenital epithelioid sarcoma. Four of five patients died of metastatic sarcoma. The courses of three patients were quite rapid, whereas a fourth patient had multiple recurrences over a long period, which is typical of extragenital epithelioid sarcoma. Complete initial excision is important. All patients with local recurrence died with distant metastases. Vascular invasion also indicates a poor outcome.

Partly luteinized theca cell tumor of the ovary.

The partly luteinized theca cell tumor is a variant of the theca cell tumor in which extensive foci of luteinization occur. This neoplasm belongs to a set of tumors, which includes the theca cell tumor, that is believed to be derived from mature ovarian stroma. This tumor can be classified as a tumor of specialized gonadal stroma of "ovarian cell type" intermediate between the theca cell tumor and the stromal luteoma. Two patients were virilized, and one had evidence of endometrial hyperplasia, whereas in the fourth no endocrine function was evident. None of the patients were pregnant at the time of discovery of the tumor. On gross examination these tumors consisted of a mixture of firm gray-white and yellow tissue. The presence of multiple yellow nodules in two tumors distinguished it from the usual theca cell tumor. A third tumor was distinctly lobulated. The tumor in only one of the cases arose in a background of ovarian stromal hyperplasia. Although the number of cases reported up to now is small and variability exists, the tumors tend to occur in patients in the early reproductive age group, often produce significant quantities of steroid hormones, and the clinical course has been benign.

Ovarian mucinous cystadenocarcinoma with mural nodule of carcinomatous derivation. A light and electron microscopic study.

A case of an ovarian mucinous tumor with a mural nodule is reported. The epithelial elements consisted of benign, low malignant potential, and invasive mucinous carcinoma. The latter was present in one focus near the surface of the mural nodule as well as in some shallow depressed areas in the cyst wall. The nodule itself was made up of highly malignant, anaplastic cells which on light microscopic examination showed some similarities to the cells previously described in the sarcomatous and in some of the sarcoma-like mural nodules. However, analysis of light microscopic features in our case showed continuity and histologic similarities between the malignant mucinous cells and the sarcoma-appearing elements in the mural nodule. Ultrastructural features also supported an epithelial origin of the cells within the mural nodule. This case is the first of its kind with light and electronmicroscopic documentation and supports an epithelial origin for some of the mural nodules in ovarian mucinous tumors.

Papillary serous carcinoma of the retroperitoneum.

We describe a retroperitoneal neoplasm in an 11-year-old girl which had a light microscopic appearance identical to that of papillary serous carcinoma of the ovary. There was no evidence of ovarian involvement. Immunohistochemical staining for amylase was positive within the cytoplasm of tumor cells. Since amylase is a marker for serous ovarian tumors, this finding supports the belief that "ovarian-type" neoplasms that occur at ectopic locations are essentially identical to their ovarian counterparts. We believe they originate from metaplasia of mesothelium. Our findings support the concept that these tumors should exhibit a biologic behavior and therapeutic response which are similar to those of an ovarian tumor of the same grade and comparable stage. The demonstration of intracytoplasmic amylase also may prove useful in differentiating peritoneal serous tumors from non-metaplastic mesothelial proliferations. We are unaware of a prior report of an extra-ovarian serous carcinoma in a child.

Bowenoid dysplasia of the vulva.

The histologic findings of five patients with clinically typical Bowenoid dysplasia (BD) allowed the authors to classify the vulvar and perineal biopsies of 18 patients under 40 years as BD and the vulvar biopsies of six patients under 40 years as squamous cell carcinoma in situ (CIS). The two best criteria for BD are cellular uniformity and absence of pilosebaceous involvement. Vesicular chromatin is a less constant feature of BD. Clinically, patients with BD were younger than those with CIS, more frequently had elevated and multiple lesions and other developed BD with pregnancy. Histologic features therefore discriminate between clinical BD and CIS, but the authors emphasize that both clinical and pathologic features are necessary for proper diagnosis. Follow-up of BD has been benign, with one exception. Spontaneous regression occasionally occurred. One patient with CIS developed microinvasive carcinoma. Patients with BD were regarded at lesser risk for invasive carcinoma than patients with CIS; they are therefore amenable to conservative therapy.

Ovarian endometrioid tumors mimicking Sertoli and Sertoli-Leydig cell tumors: Sertoliform variant of endometrioid carcinoma.

We have encountered four cases of an unusual variant of well-differentiated endometrioid carcinoma that was predominantly composed of tubules, solid or hollow, as well as cord-like areas histologically mimicking Sertoli and Sertoli-Leydig cell tumors. The two features most helpful in differential diagnosis were the presence of areas of tumor with the typical confluent pattern of endometrioid carcinoma, and the presence of mucin at the apical borders of the tumor cells and/or within glandular lumina. Other features that were helpful if present, but were observed only in one case each, were foci of squamous metaplasia or the presence of ciliated epithelium. In two cases, ultrastructural studies showed well developed microvilli and perinuclear microfilaments confirming the endometrioid nature of the neoplasm. The patients varied from 22-74 years in age. All tumors were confined to a single ovary, and no tumor is known to have recurred or metastasized. One of the patients died at age 80, six years following operation, presumably without evidence of recurrent neoplasm or metastases. Two other patients are living and well, one and 14 years after diagnosis. In one patient follow-up is short. The clinicopathologic features of this variant of endometrioid carcinoma are reviewed with emphasis on differential morphologic features.
