Giant intraosseous Schwannoma of the calcaneus
نویسندگان
چکیده
Schwannoma is a benign nerve sheath neoplasm which mainly locates in the soft tissue but rarely originates in the bone. Intraosseous Schwannoma is prone to occur in the mandible and sacrum, while its occurrence is seldom seen in the calcaneus. Herein we report an 18-year-old man with a chief complaint of pain in the right heel. Radiographs revealed a huge, osteolytic, and expansile lesion with well-defined margins in the right calcaneus. Then, an open biopsy was performed and the frozen-section test revealed benign spindle cell tumor. Consequently, the curettage and allograft bone implantation were performed. And the postoperative pathologic results confirmed the diagnosis of intraosseous Schwannoma. The aim of this report is to bring attention to the possibility of Schwannoma in the differential diagnosis of benign-appearing osseous neoplasm in the calcaneus.
