Lipofibromatous hamartoma of the median nerve. Three case reports.

Nervous lipofibromatous hamartoma is a rare tumour-like condition involving the peripheral nerves, whereby the epineurium and perineurium are enlarged and distorted by excess fatty and fibrous tissues that infiltrate between and around nerve boundaries. The median nerve is much more likely than other nerves to develop a hamartoma with a predilection for the carpal tunnel. In this article, we describe three cases of lipofibromatous hamartoma of the median nerve and discuss its management.
