Périneuriome extraneural des tissus mous localisé au nez

Extraneural soft tissue perineurioma is usually a benign nerve sheath tumour composed mainly of perineurial cells. Our case occurred in a 24-year-old Caucasian adult. The tumour generally presents as a unique cutaneous nodule corresponding histologically to a well-delineated dermal fusocellular proliferation organized in a storiform pattern that stains positive for EMA and negative for S100. The tumour is usually localized to the trunk and extremities. Location on the nose as in our patient has been rarely reported. Surgical removal of the tumour is the treatment of choice.
