Primary Pigmented Nodular Adrenocortical Disease: Reevaluation of a Patient with Carney Complex 27 Years after Unilateral Adrenalectomy

Abstract

A 45-yr-old man with primary pigmented nodular adrenocortical disease (PPNAD) is described. This patient underwent unilateral adrenalectomy for ACTH-independent Cushing's syndrome (CS) in 1969. Although his daily urinary free cortisol (UFC) excretion rate normalized, and the major clinical manifestations of CS subsided, loss of a circadian cortisol rhythm persisted after surgery. Twenty-seven years later, the patient presented again with short stature, severe osteopenia, skeletal deformities, thinning of the skin, and myopathy.
