Primary cutaneous mucoepidermoid carcinoma of thigh

Mucoepidermoid carcinoma (mec) of the skin is an exceedingly rare but distinct neoplasm with respect to its histopathological features. it is similar,if not identical to mec of the salivary gland,a neoplasm whose prognosis is correlated with the pathologic grade. we present two cases of primary cutaneous mucoepidermoid carcinomas,presenting as a cystic lesion of the thigh. no other tumors were found in the thoroughly examined patients. histologically both these cases had the characteristics of primary cutaneous mec. this is a very rare presentation of a non salivary gland mec.
