Atypical Pleomorphic Lipomatous Tumor of the Right Hand Mimicing Venous Malformation
We present the case of a 31-year-old woman who was referred with a 12-month history of a tumor on the ulnar side of her dominant right hand. The eventual histopathologic diagnosis was an atypical pleomorphous lipomatous tumor, an entity that has only been recently classified in the World Health Organization Classification of Soft Tissue and Bone Tumors.Extensive Tumoral Calcinosis of the Hand
Tumoral calcinosis is a rare and benign subtype of calcinosis cutis, a group of disorders involving soft tissue calcium deposition. Only 250 cases have been described since 1898; hand involvement is exceedingly rare. We report a case of extensive calcinosis within the flexor sheath of the little finger. Presentation included a painful mass over the volar aspect of the little finger, restricted digit motion, and skin compromise at the site of the mass. Surgical debulking was performed resulting in restoration of finger function.Mucormycosis Osteomyelitis of the Hand
Mucormycosis is a relatively uncommon but highly aggressive fungal infection caused by the Mucormycotina subgroup of fungi. Mucormycosis usually affects the skin, sinuses, or lungs of an immunocompromised host. Other risk factors for development of mucormycosis include hematologic malignancy, intravenous drug abuse, chronic steroid use, and contaminated traumatic wounds. Cutaneous mucormycosis of the hand involving the skin and soft tissues is rare but has been reported previously. In this case report, we review the clinical course of a patient with mucormycosis of the hand who was found to have extensive soft tissue and bony destruction and ultimately required amputation.Reversed Palmaris Longus Muscle Causing Volar Forearm Pain and Ulnar Nerve Paresthesia
A case of volar forearm pain associated with ulnar nerve paresthesia caused by a reversed palmaris longus muscle is described. The patient, an otherwise healthy 46-year-old male laborer, presented after a previous unsuccessful forearm fasciotomy for complaints of exercise exacerbated pain affecting the volar forearm associated with paresthesia in the ulnar nerve distribution. A second decompressive fasciotomy was performed revealing an anomalous “reversed” palmaris longus, with the muscle belly located distally.
