A patient with rhabdomyosarcoma and clear cell sarcoma of the skin.
We describe a patient with rhabdomyosarcoma of the posterior cervical region and clear cell sarcoma on the occipital scalp. These two tumors later metastasized to distant skin. We differentiated these tumors by histopathologic, histochemical, immunohistochemical, and ultrastructural findings. Cells of the posterior cervical tumor showed differentiation toward striated muscle, whereas those of the occipital tumor showed findings compatible with melanocytic differentiation.
