Multiple endocrine neoplasia type 1 presenting as rosacea.

We present a case of malignant carcinoid initially diagnosed as rosacea. This patient was later found to have an additional functioning parathyroid tumour. Although a pituitary tumour was not identified, the association represents a probable case of multiple endocrine neoplasia type 1 (MEN 1). This autosomal dominant syndrome is characterized by tumours of the pancreas, parathyroid and pituitary. Inoperable carcinoid tumour is best treated with a long-acting somatostatin analogue, octreotide. A diagnosis of MEN 1 has important connotations for the proband's first-degree relatives, who should be entered into an appropriate screening programme.
