A case‐matched molecular comparison of extraovarian versus primary ovarian adenocarcinoma

Extraovarian müllerian adenocarcinoma (EOM) resembles primary ovarian carcinoma (POC) both histologically and clinically, yet little is known regarding the molecular genetic characteristics of this entity. The objective of this study was to compare the expression of three molecular markers of tumor behavior in EOMs and POCs.

Buttock necrosis after uterine artery embolization.

BACKGROUND: Uterine artery embolization is an increasingly popular alternative to hysterectomy or myomectomy for treatment of symptomatic uterine leiomyomata. CASE: A woman with a symptomatic uterine fibroid developed 2 areas of full-thickness necrosis on her right buttock following uterine artery embolization. After surgical debridement, healing occurred over 14 weeks. CONCLUSION: Buttock necrosis is a possible complication of nontarget embolization during uterine artery embolization.

The factor V Leiden mutation and the risk of venous thromboembolism in gynecologic oncology patients

OBJECTIVE To measure the strength of the association between the factor V Leiden mutation and venous thromboembolism in gynecologic oncology patients. METHODS We conducted a case‐control study of gynecologic cancer patients in a referral center who were group matched for demographics, tumor type, and treatment. The prevalence of the factor V Leiden mutation was determined in both cases and controls, and an odds ratio was calculated. The factor V Leiden mutation was detected using polymerase chain reaction amplification and nucleic acid restriction digest of deoxyribonucleic acid extracted from leukocytes. RESULTS Seventy‐five patients were enrolled in the study. Seventy‐four samples were available for analysis. There were no differences between the cases and controls with respect to age, race, body mass index, smoking, cancer type, high stage (III or IV) of cancer, or treatment modality. The odds ratio for having the factor V Leiden mutation in patients with venous thromboembolism was 0.3 (95% confidence interval 0.1, 1.7). CONCLUSION This study suggests that the factor V Leiden mutation is not associated with an increased risk of venous thromboembolism in gynecologic oncology patients. This contrasts with other studies showing a strong association between the factor V Leiden mutation and venous thromboembolism in cases of previously unexplained venous thromboembolism, and venous thromboembolism associated with other hypercoagulable states, such as pregnancy and oral contraceptive use. The risk of venous thromboembolism due to cancer outweighs the contribution of the factor V Leiden mutation.

Choriocarcinoma in a term placenta with maternal metastases

Choriocarcinoma of the nonmolar placenta is presumptively a rare entity and is usually associated with widespread maternal metastases at the time of diagnosis. Nonmetastatic disease goes unrecognized and undiagnosed because placental carcinoma can be limited to a few villi, and grossly evident disease is often misinterpreted as a placental infarct. The optimal treatment for patients with choriocarcinoma of the placenta is not known but aggressive combination chemotherapy is suggested for patients with metastatic disease. Historically, the prognosis for both mother and infant has been poor.

Cervical cancer metastatic to the breast: a rare presentation of tumor dissemination.

Metastatic disease presenting in the mammary gland from gynecologic malignancies is a rare occurrence. A case of metastatic adenosquamous carcinoma of the cervix presenting as an inflammatory breast lesion is reported. Metastases within the breast have distinct clinical, radiographic, and histologic features and should be suspected in a patient with a breast mass and a known extramammary primary. As with other distant metastases of cervical cancer, mammary gland involvement portends a poor prognosis.

Pulmonary lymphangitic carcinomatosis secondary to cervical carcinoma: A case report

Pulmonary lymphangitic carcinomatosis is a rare form of metastatic cervical cancer. A patient with persistent squamous cell carcinoma of the cervix presented with symptoms suggestive of pulmonary embolism and right heart failure. Pulmonary lymphangitic spread of the cancer was found postmortem. The pathogenesis of pulmonary lymphangitis carcinomatosis is reviewed and diagnostic evaluation discussed.

Disseminated granulomatous disease (BCGosis) following chemoimmunotherapy for ovarian carcinoma

The use of BCG (bacille Calmette Guérin) in conjunction with cytotoxic chemotherapeutic agents has been advocated in patients with ovarian carcinoma. We describe a patient with stage III, grade I, endometrioid carcinoma of the ovary treated with cisplatin, doxorubicin, cyclophosphamide, and BCG. Following one course of therapy she presented with an elevated temperature, purpuric skin rash, abnormal liver function tests and hematological indices, and multiple organ failure resulting in sepsis and death. At autopsy, disseminated noncaseating granulomas were found in the lungs, hilar lymph nodes, liver, and spleen. Metastatic carcinoma was not present in these organs. This report describes the rapid onset of a disseminated BCG infection (BCGosis) in a patient with ovarian carcinoma receiving chemoimmunotherapy. Clinical recognition of BCGosis in immunocompromised patients is difficult but should be considered in the differential diagnosis of patients presenting with unexplained febrile illness, functional abnormalities in multiple organ systems, and a history of immunotherapy with BCG. Appropriate specimen collection is emphasized.

Endodermal sinus tumor of the ovary: A case series with flow cytometric DNA content analysis

Endodermal sinus tumors (EST) are rare germ cell ovarian malignancies occurring primarily in young women. A retrospective review of the Magee-Womens Hospital tumor registry revealed eight cases of pure EST and two mixed tumors in which the EST component was predominant. Mean patient age was 18.2 years. Abdominal pain was the most common presenting symptom and a pelvic mass was palpable in all patients. Four patients are currently alive and well with no evidence of disease. All were treated with surgery and combination chemotherapy. Flow cytometric DNA content analysis of paraffin-embedded tumor tissue identified similar aneuploid cell populations in three of five tumors analyzed with relative peak positions of 1.72, 1.62, and 1.70. The management of women with endodermal sinus tumor remains controversial with regard to type of chemotherapy employed and the use of second-look laparotomy. The prognosis role of flow cytometric DNA content analysis is yet to be determined.
