[Malignant vulvar soft tissue myoepithelioma].
The authors describe a case of malignant vulvar soft tissue myoepithelioma in a 41-year-old woman. Microscopically, epithelioid and spindle cells were located in the myxoid stroma. Tumor cells co-expressed pan-cytokeratin, EMA, and cytokeratin 18, vimentin, protein S100, and smooth muscle actin. The tumor was found to have a very high proliferative activity (Ki-67 was as high as 80%). The disease was fulminant with a fatal outcome 4 months after the occurrence of the first symptoms of the tumor.
