Two patients with Cushing's disease in a kindred with multiple endocrine neoplasia type I.

Abstract

Cushing's disease (pituitary ACTH-dependent Cushing's syndrome) has been described in association with the syndrome of multiple endocrine neoplasia type I (MEN-I). Cushing's disease is uncommon in MEN-I and has not been reported in more than one member of a kindred. Here we describe a mother and her daughter with Cushing's disease and major depressive disorder. The mother, her other daughter, and two other relatives also had primary hyperparathyroidism. We believe this to be the first reported instance of hereditary Cushing's disease as a manifestation of MEN-I.
