Abstract
We report a case of intraneural perineurioma, developed In the left cubital nerve, in a five-year old girl. This intraneural tumor is rare and shows a typical histologic appearance : concentric whorls of perineurial cells EMA +, PS100-, around nerve fibers. This tumor must be distinguished from extra neural or soft tissue perineurioma, also composed of perineurial cells, wit h distinct clinical presentation and histological appearance.
