Primary giant cell malignant fibrous histiocytoma-associated with renal calculus

Abstract

Malignant fibrous histiocytomas (MFH) are the most commonly seen soft tissue sarcomas in adults. It is rarely seen in some visceral organs. Kidneys are the parenchymal organs in which MFHs are most frequently seen. More than 50 cases of primary renal MFH have been reported. Among these cases, only 1 was reported as primary giant cell subtype in association with urolithiasis. This case report is the second such case with the these characteristics.
