Abstract

A 42-year old female reported atraumatic painful swelling in her left ankle and heel since one month. X-ray showed an expansile lytic lesion with thinning of cortex at the anterior end of the left calcaneum. Curettage of the lesion was done and cavity packed with composite bone graft. Postoperative period was uneventful, and patient was ambulatory without aid. Histopathology report showed intraosseous schwannoma. Intraosseous schwannoma is a very rare tumor accounting for only 0.2% of all primary bone tumors. This is the second case of intraosseous schwannoma of calcaneum reported as per literature.
