Synovial Chondromatosis in Patient Presenting with Chronic Venous Stasis Ulcers.

Synovial chondromatosis (SC) is a rare, benign synovial growth most frequently involving the knee or hip joint. Common presenting symptoms include pain throughout the affected joint, reduced range of motion, and a palpable mass. We present an unusual case of SC presenting with symptoms of chronic venous stasis ulcer. A 49-year-old patient presented with swelling, hyperpigmentation, and ulcerations of his right lower extremity. Work-up including duplex and computed tomography scan revealed a calcified mass in the hip joint, highly suspicious for SC. A joint surgical approach from a vascular and orthopedic surgeon successfully removed the growths and decompressed the surrounding vessels. The mass effect of the SC on overlying veins resulted in obstruction of venous return due and subsequent venous stasis ulcerations and symptoms of venous hypertension. We present this case due to the unique vascular sequelae related to the SC to explore this as a new diagnosis to consider in patients who present with venous stasis ulceration and radiographic findings consistent with SC.
