Descripción
Sumario:Epithelioid malignant peripheral nerve sheath tumor (EMPNST, malignant epithelioid schwannoma) is a rare variant of malignant peripheral nerve sheath tumor that has morphologic and immunophenotypic overlap with a variety of epithelioid neoplasms. Because of its rarity it may be potentially underrecognized. We describe a case arising in the subcutis of the thigh in a 25 year-old female, and discuss the pathologic features and differential diagnosis.
