title: Epithelial mesothelioma with deciduoid features.
abstract: A rare case of malignant mesothelioma in a 15-year-old girl is described. The patient presented with secondary amenorrhoea and clinical symptoms resembling those of an ovarian cyst. One large and multiple small peritoneal nodules were found at laparoscopy. Histologically the tumour was characterised by an unusual pattern with a superficial resemblance to decidual reaction, but because of significant mitotic activity the diagnosis of a malignant tumour, epithelial mesothelioma with deciduoid features, was made. The patient died 11 months after diagnosis. Post-mortem examination revealed extensive extraperitoneal spread.
