Lipofibromatous Hamartoma in a Hispanic Patient with macrodactyly: a rare peripheral nerve tumor causing recurrent carpal tunnel syndrome.

This is a rare case of a 42-year-old Hispanic male with macrodactyly who presented with recurrent carpal tunnel syndrome (CTS) due to Lipofibromatous Hamartoma (LFH). A slowly growing mass in his right palm with pain and numbness, along with motor and sensory deficits in the median nerve distribution, was reported since the past year prior to visit. Previous open carpal tunnel release was performed at 16 years of age due to CTS without complications. The diagnosis of LFH was made based on ultrasound, electromyography test and physical examination. An extended open carpal tunnel release with transection of transverse ligament was performed. The 24-month postoperative evaluation showed complete resolution of symptoms. This report illustrates the management of a recurrent CTS due to LFH in a Hispanic adult patient with macrodactyly that was successfully treated with a carpal tunnel decompression.
