We report long-term results of carpal tunnel release in two cases of Fibrolipomatous hamartoma (FLH) of the median nerve. Case 1 is an 8-year-old boy with a two-month history of a mass in his left palm, and case 2 is a 27-year-old man with a mass in his right palm and a three-month history of mild paresthesia affecting the thumb and index finger of his right hand. Though both cases were treated only by carpal tunnel release without biopsy or tumor excision, symptoms did not become worse and tumor enlargement was not seen during 5 and 15 year follow-up. Therefore, in cases of FLH with carpal tunnel syndrome symptoms, we recommend release of the carpal tunnel alone as a primary operation.
