Cushing disease presenting as arthritis.

Cushing's syndrome is an endocrine disorder caused by hypercortisolism. Despite its varied clinical spectrum of presentation, Cushing's disease has not been reported to present as arthritis. Moreover, keratilysis exfolitiva has not been described in Cushing disease. We report a 12 year old male child with pituitary micro adenoma initially presenting as arthritis and developing keratilysis exfolitiva.
