Lipofibromatous Hamartoma of Digital Nerve: A Case Report

A 9-year-old girl was investigated for a long-standing soft tissue swelling in her ring digit that recently developed tenderness and rapid growth within the last 3 months before presentation. Exploration of the swelling was done meticulously with total excision of the swelling from within its attachment to the digital nerve. The swelling was then sent for histopathological examination. The pathology report stated the presence of mature adipose tissue intersected by fiprocellular collagenic stroma infiltrating perineurium, epineurium, and nerve fascicles, which established the diagnosis of lipofipromatous hamartoma (LFH) of the nerve. LFH is a rare benign neoplasm that mainly affects the median nerve, but other nerves all over the body were also reported. Women are more affected than men.
