## BACKGROUND. Clear cell sarcoma, or malignant melanoma of soft parts, is a rare tumor that occurs predominantly in the extremities of young adults. The importance of surgery has been well established. However, the role of adjuvant radiotherapy has yet to be determined.

β¦ Synopsis
BACKGROUND.
To the authors' knowledge, there has been no previous report of primary maligiiant melanoma of bone.
METHODS.
A 33-year-old woman presented with a tumorous lesion in the olecranon of the right ulna. The histologic diagnosis was malignant melanoma with close similarity to clear cell sarcoma. To exclude the possibility of malignant melanoma metastatic to the bone, clinical investigations including gallium 67- citrate scintigraphy, brain, chest, and abdominal computed tomography, and upper and lower gastrointestinal endoscopic examinations were performed. Conventional histopathologic, immunohistochemical, and electron microscopic studies were also performed.
