Abstract:
Fibrolipomatous hamartoma is a rare benign tumor characterized by infiltration of fibrous and adipose tissue found within the epineurium and perineurium of the distal peripheral nerves. Most commonly seen in the upper extremities and median nerve, it is rarely involved in the foot and ankle. We report a rare case of fibrolipomatous hamartoma found in the great toe of a 25-year-old patient. Magnetic resonance imaging demonstrated a heterogeneous mass, confirming the mass was solid rather than a fluid collection. Surgical excision revealed a fatty, fibrous, well-demarcated, encapsulated, solid soft-tissue mass. A surgical excision was performed and a pathologic diagnosis of fibrolipomatous hamartoma was made.

Nerves
The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports the...
