- Abstract
Schwannomas (also called neurilemmomas) are slow-growing nerve sheath tumors derived from Schwann cells. However, intraosseous schwannoma is a rare entity with an incidence of only 0.2% in overall primary bone tumors. The purpose of this case report is to present a case of an intraosseous schwannoma of the calcaneus. A 35-year-old woman was admitted to our outpatients’ clinics with a complaint of long-time right heel pain (for approximately eight months). After a suspicious cystic lesion was observed on the patient’s plain radiograph examination, a magnetic resonance imaging (MRI) was performed. The MRI showed a 22 × 20 mm intraosseous cystic lesion at the posterior part of the calcaneus. Extended curettage and iliac bone grafting were performed. In the presence of postoperative histopathologic and immunohistochemical examination, histopathologic diagnosis of the patient was reported as intraosseous schwannoma. After 4 weeks of nonweight-bearing, she completely recovered with no pain. In conclusion, intraosseous schwannoma of the calcaneus must be kept in mind for patients who have chronic heel pain.
