Abstract: A 53-year-old man presented in 2009 with a tumor over the dorsum of his hand and wrist. Magnetic resonance imaging was performed before surgery and histopathological and immunohistochemical studies were performed after surgery. This demonstrated an ill-defined lesion measuring 46 mm × 31 mm confined to the subcutaneous tissues, extensor tendons, and articular capsule on the dorsum of the hand and wrist with heterogeneous intermediate and high T1 and T2 signal suggesting a complex mixture of fat and fibrous elements. A histopathological differential diagnosis of hemosiderotic fibrohistiocytic lipomatous lesion/tumor (HFLL/T) and giant-cell tumor of tendon sheath and fibroma of tendon sheath was made. We describe this rare lesion and call attention to important points in diagnosis.
