This case report describes a rare presentation of primary giant cell malignant fibrous histiocytoma associated with a renal calculus, highlighting the need to consider malignancy in patients with renal stones and rapid weight loss.
Alerts clinicians to rare renal sarcomas in stone-associated masses; leaves open any etiologic link for further study.
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.
