Carcinoma of the thyroid gland, adenoma of the adrenal cortex and peptic ulcer: an unreported association.

A 39-year-old man, operated on for duodenal ulcer, was found to have a papillary carcinoma of the thyroid, an aldosterone-producing adenoma of the adrenal cortex, and a recurrence of a peptic ulcer. The probable coincidental occurrence of these diseases in this patient is suggested. Nevertheless, careful investigation of the other endocrine glands in patients with endocrine tumors is recommended.
