Abstract
A 44-year-old man was admitted to our hospital with severe back pain continuing for 12 years. Computed tomography of the chest revealed a 14 mm diameter tumor with calcification located in the right seventh rib. We performed right seventh rib and sixth to seventh intercostal muscle partial resection. Microscopically, the tumor showed typical features of a schwannoma composed of Antoni A and Antoni B tissues. The tumor had positive immunohistochemical staining for S-100 protein. The pathological diagnosis was intraosseous schwannoma. The patient's severe back pain disappeared and there was no recurrence or metastasis of the tumor during a 1-year follow up.
