title: [Desmoplastic small round cell tumour of the pancreas with breast metastasis].
abstract: Desmoplastic small round cell tumour (DSRCT) is a very rare, highly aggressive neoplasm. Most cases have been reported in adolescent and young male patients. These tumours occur mainly in the peritoneal cavity, with peritoneal and lymphatic dissemination. Their histologic features are unspecific and immunohistochemistry and cytogenetic or biomolecular techniques are required for their diagnosis. Involvement of the pancreas is exceptional and is difficult to differentiate from other pancreatic primary tumours. We report here the case of a 49-year-old woman who had a DSRCT of the pancreas with metastasis to the breast. She died within one year after the diagnosis despite an aggressive surgical strategy.
