Clear cell sarcoma (malignant melanoma of soft parts): Fine-needle aspiration cytology of a highly pigmented tumor.

摘要

Diagnosis of clear cell sarcoma by fine-needle aspiration is difficult, as melanin is usually absent. Here we describe a case of a primary clear cell carcinoma with abundant melanin, making diagnosis definitive. Diagn. Cytopathol. 2003;28:313-315.
