Ovarian clear cell adenocarcinoma: a continuing enigma

Ovarian clear cell adenocarcinomas (OCCAs) account for <5% of all ovarian malignancies. Compared to other epithelial ovarian cancer (EOC) subtypes, when at an advanced stage, they are associated with a poorer prognosis and are relatively resistant to conventional platinum-based chemotherapy. By contrast, early-stage clear cell ovarian cancer carries a relatively good prognosis. Hence, there is a need to improve our understanding of its pathobiology in order to optimise currently available treatments and develop new therapeutic strategies. This review summarises the currently available literature regarding the pathogenesis of OCCA, its molecular genetic features and postulated molecular mechanisms that underlie its chemoresistant phenotype. Marked similarities with clear cell carcinomas of the kidney and endometrium have been noted by some investigators, raising interesting possibilities regarding novel therapeutic approaches. Unfortunately, most studies on OCCA have hitherto been hampered by insufficient sample sizes, leaving many key issues unresolved. It is envisaged that in the future, high-resolution genomic and gene-expression microarray studies incorporating larger sample sizes will lead to the characterisation of the key molecular players in OCCA biology, which may potentially lead to the identification of novel targets for therapeutic development.     

Tumor-to-tumor metastasis: case report of a pulmonary adenocarcinoma metastatic to a clear cell renal cell carcinoma

Tumor-to-tumor metastasis is a very rare event. The recipient tumor may be benign or malignant. Renal cell carcinoma is the most common tumor recipient of metastasis while lung carcinoma is the most common donor tumor. We report a 57-year-old Caucasian male who presented with chest pain. On PET CT Scan, he was also found to have a large renal mass for which he underwent left nephrectomy. On histology of the renal mass, the tumor was a conventional renal cell carcinoma with areas of metastatic non-small cell lung carcinoma. The two components had a distinctive morphology which was confirmed on subsequent immunohistochemistry. The physiopathological mechanisms making clear cell renal cell carcinoma an avid recipient of a metastatic carcinoma have been speculated upon, but are still unknown.     

Ovarian mucinous tumour with a focus of anaplastic carcinoma: a case report

A 50-yr-old patient presented with abdominal symptoms due to the presence of cystic ovarian tumours. After hysterectomy and bilateral salpingo-oophorectomy, the diagnosis of a mucinous tumour with a focus of anaplastic carcinoma in one ovary and a dermoid cyst in the other was made. Further treatment was refused and the patient died 12 mth after operation with disseminated anaplastic carcinoma. The case is the first reported when adjuvant therapy has not been given and illustrates the poor natural history of this disease.     

Primary vaginal clear cell adenocarcinoma accompanied by Herlyn-Werner-Wunderlich syndrome without prenatal diethylstilbestrol exposure: a case report

We report a rare case of a 40 years old woman with primary vaginal clear cell adenocarcinoma (CCA) accompanied by Herlyn-Werner-Wunderlich syndrome (HWWS) and without any prenatal diethylstilbestrol exposure. Pathological results indicated that the CCA was surrounded by adenosis and that there was a benign to malignant transformation of several glands in the epithelium, so the CCA was believed to have arisen from the adenosis. The literature review disclosed that genitourinary anomalies might be associated with an increased risk of adenocarcinoma, but the mechanism was not clear.

The first Congolese case of cervical clear cell adenocarcinoma

The authors report the first Congolese case of uterine cervix clear cell adenocarcinoma in a menopausal multipara, whose mother had not been treated by diethystilboestrol (DES). The histological diagnosis was made on embedded-paraffin samples, stained by HE and PAS. Discharged from hospital on parents' request in order to be on infusion and brew-based traditional treatment, the patient died at home two months after diagnosis.     

Ovarian serous borderline tumors with stromal microinvasion: a report of 21 cases

The clinicopathologic features of 21 cases of otherwise typical serous borderline tumors that contained small foci of stromal invasion were reviewed. The mean age of the patients was 43 years and six of them were pregnant at the time of diagnosis. Nineteen tumors were stage I, one was stage III (para-aortic lymph node involvement) and one was stage IV (parenchymal liver metastasis). The tumor invaded the stroma predominantly as individual cells or nests or clusters of cells with abundant eosinophilic cytoplasm (17 cases), as small confluent nests with a cribriform pattern (two cases) and as rounded aggregates of papillae (two cases). Seven women were treated with bilateral salpingo-oophorectomy and hysterectomy; 13 had less than bilateral oophorectomy. Of the 17 patients for whom followup data were available, 16 were without evidence of disease 1 to 11 (mean, 5.2) years postoperatively, and one patient had a serous borderline tumor with microinvasion in a conserved contralateral ovary 2.8 years postoperatively, but was well 6 months after a partial oophorectomy. These data suggest that serous borderline tumors with microinvasion have a prognosis similar to that of the usual serous borderline tumor, and that conservation of the contralateral ovary and uterus may be acceptable therapy in young women who wish to preserve their fertility.
