Lipofibromatous hamartoma of the median nerve with long-term follow-up.
Lipofibromatous hamartoma is a rare, benign tumor that most often involves the median nerve. A 16-year-old male with lipofibromatous hamartoma of the median nerve at the wrist level is described. This patient was a child when the mass was first noted. Although there were no symptoms or signs of carpal tunnel compression, the growth of the tumor was progressing. In addition to the release of the carpal tunnel, microsurgical intraneural dissection was done to preserve the thenar motor branch. Then segmental excision of the residual sensory component with sural nerve grafting was performed. Subjectively the patient did not notice the minor motor deficit, however, the patient did experience numbness of fingertips after surgery. There were no scars or trophic ulcers on fingertips at 3 years of follow-up regardless of the inadequate sensory return. Treatment of this benign tumor is still controversial. The relevant reports in the literature are reviewed.
