IDIOPATHIC CARPOTARSAL OSTEOLYSIS WITH BARTTERS-SYNDROME - A CASE-REPORT AND REVIEW OF THE LITERATURE

Idiopathic carpotarsal osteolysis is 1 of the rare types of disappeari ng bone diseases characterized by painful limitation of movement and d eformity of the wrist and tarsal joints, and associated with frequent episodes of joint inflammation and a radiographic appearance of osteol ysis. Reported here is an 8-year-old girl with idiopathic carpotarsal osteolysis and Bartter's syndrome with significantly decreased reabsor ption of chloride at distal renal tubules, low level of serum potassiu m, a metabolic alkalosis, and high levels of aldosterone and renin. Ba rtter's syndrome associated with idiopathic carpotarsal osteolysis has not been published previously. The typical plantar nodule in this pat ient confirmed the presence of fibromatosis with aggressive histologic signs in light and electron microscopic examination.
