Extraneural perineurioma of the face: an unusual cutaneous presentationof an uncommon tumour

Perineurioma is an uncommon, benign tumour of the peripheral nerve sheath that has two major clinicopathological forms - intraneural and extraneural. We present a case of extraneural perineurioma that occurred at an unusual site - the facial skin of a 70-year-old woman - which illustrates the wide, and potentially misleading, clinicopathological spectrum of this poorly recognized tumour.
