Melanin containing clear cell sarcoma in a fingertip. Case report and review of the literature.
A case is described of a clear cell sarcoma with ultrastructural evidence of melanin production. The tumour appeared on the distal portion of the index finger of a thirteen-year-old girl and showed little change in size over seven years of observation by the patient. At age twenty she required hospital admission at which time clinical evidence of metastases to axillary nodes, lungs and bone was found and the patient died within two months. The previous cases reported in the literature are discussed.
