Multiple glomus tumors in chest wall and buttocks

We report a case of a 50-year-old man with multiple glomus tumors of the chest wall and buttocks. He was admitted to our hospital because of right chest pain for 10 years. The chest pain was lancinating and gradually increasing. A computed tomography (CT) showed a mass in the right 3rd intercostal space and a mass in the right buttocks. The chest tumor was enhanced with contrast medium on chest CT. Two tumors were resected completely including the 4th rib. Histological examination showed numerous vascular space lined with sheets of epithelial cells (glomus cells), so they were diagnosed as glomus tumor. The postoperative course was well, and the pain disappeared after resection. The glomus tumor of chest wall could be diagnosed as malignant tumor, based on the criteria of the size more than 2 cm and deep location. The glomus tumors which occurred in the chest wall and buttocks were very rare. We presented the case with reference to the literature.
