Intraneural perineurioma of the oral mucosa

A 16-year-old boy presented with an intraneural perineurioma arising from a small nerve in the buccal mucosa. Histologically, the tumour comprised a tortuous proliferation of spindle cells arranged like an onion bulb. To our knowledge this is the third example of an intraneural perineurioma that did not present in a major nerve.
