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