Small Cell Ovarian Carcinomas - Characterisation of Two Rare Tumor Entities.

Small cell ovarian carcinomas (SCOC) are differentiated into two types: hypercalcaemic (SCOCHT) and pulmonary (SCOCPT). Unfortunately, little is known about pulmonary-type small cell ovarian carcinoma. We carried out a systematic analysis of all available reports in the literature on individual cases of SCOCHT and SCOCPT.

Primary malignant melanoma of the urethra: a systematic analysis of the current literature.

Background: Primary malignant melanoma of the urethra is a rare tumour that most commonly affects the meatus and distal urethra. General prognosis seems to be poor. To date, there have been no systematic reviews on this topic.

Small cell carcinoma of the ovary of the hypercalcaemic type: an analysis of clinical and prognostic aspects of a rare disease on the basis of cases published in the literature.

Purpose: Ovarian small cell carcinoma of the hypercalcaemic type is a very rare and highly aggressive malignant disease, mainly affecting young women. Due to the rarity of this tumour entity, prospective randomised trials are unlikely to be conducted, and the only retrospective analysis based on a large case series is from 1994. Since diagnostic and treatment modalities may have changed, we initiated this analysis.
