Vulvar "proximal-type" epithelioid sarcoma: report of a case and review of the literature.

BACKGROUND: The "proximal-type" epithelioid sarcoma is a very rare kind of mesenchimal tumor characterized by the difficulty in histological diagnosis and the very aggressive biological behavior. CASE: We report of a case of a 63 years old woman with a vulvar "proximal-type" epithelioid sarcoma that underwent a radical surgical staging followed by an adjuvant radiotherapy. She is on follow-up care for 14 months and there is no clinical evidence of disease. CONCLUSION: Even if quite rare the proximal type epithelioid sarcoma should be regarded as a separate entity of particularly aggressive biologic behaviour. Its diagnosis attracts controversies and criticism related to the surgical approach and the choice of an adjuvant therapy.
