Abstract
A 62-year-old woman had had coccygodynia since May 1998, and noticed a swelling around coccygeal bone on May, 1999. She was referred to our hospital on August 25, 1999. Pelvic computed tomography and magnetic resonance imaging showed a tumor, 6cm×6cm wide and 4.5cm high, over the coccygeal bone. The tumor was excised together with the periosteum of coccygeal bone. The histological diagnosis of this tumor was chordoma. Subsequently local recurrence and metastases to liver, lung, and lymph node developed in February, 2000. The patient died on July 17, 2000. Chordoma is a low-grade malignant tumor originating from remnants of the notochord. We, dermatologists, should consider chordoma as a differential diagnosis when we encounter a tumor or subcutaneous nodule on the sacrococcygeal region. [Skin Cancer (Japan) 2000; 15 : 271-275]
