Clear cell sarcoma: a case report with radiological and pathological features of an atypical case.

Clear cell sarcoma of soft tissue is a rare, aggressive soft tissue tumor, which is morphologically similar to malignant melanoma but has no precursor skin lesion and, instead, has a characteristic chromosomal translocation. It is critical, yet challenging, to recognize clear cell sarcoma of soft tissue because the outcome is very different to that of metastatic melanoma. We report a case of clear cell sarcoma of soft tissue arising in the left foot of a 35-year-old African-American woman.
