Ewing's sarcoma (ES) and primitive neuroectodermal tumor (PNET) are closely related malignant neoplasms, usually affecting the skeletal system. Extraosseous ES/PNETs are uncommon, with occasional reports of tumors affecting the genitourinary tract. Only few cases of primary vulvar Ewing's sarcoma/PNET have previously been reported.
We present a patient with primary vulvar Ewing's sarcoma with pulmonary metastasis who presented at the Department of Gynecology and Obstetrics, University of Schleswig-Holstein, Campus Luebeck.
The present report is the third case of a primary vulvar Ewing's sarcoma and the first constellation with pulmonary metastasis at diagnosis in the current literature. We present the diagnostic and therapeutic management including surgery, chemotherapy and radiation.
The treatment of the Ewing's sarcomas and PNETs requires a multidisciplinary systemic approach. Despite its rarity, the differential diagnosis of vulvar sarcoma must be considered in young women.
