Périneuriome réticulaire du nerf tibial

Reticular (retiform) perineurioma is a rare variant of soft tissue perineurioma developed from the perineurium. This benign tumor is characterized by strands of spindle cells in a fibro-myxoid matrix surrounding pseudocystic mucoid spaces. We report a tibial nerve reticular perineurioma in a 35-year-old patient.
