title: An unusual variant of multiple endocrine neoplasia syndrome: a case report.
abstract: A case of multiple endocrine neoplasia syndrome (MEN) in a 57-year-old woman with multiple endocrine tumours involving the pancreas, parathyroid and thyroid glands is reported. An unusual feature was the presence of collision tumours in the pituitary and adrenal. In the pituitary there were adenomas and a meningioma whereas in the adrenal there was a carcinoma along with a myelolipoma. Such collision tumours in the pituitary and adrenal as components of MEN syndrome have not been previously described.
