Abstract
This report presents the first case of low-grade fibromyxoid sarcoma (LGFMS) arising from the vaginal wall (a rare soft-tissue sarcoma of subfascial planes) and draws attention to differential diagnosis of masses arising from the vaginal wall. A patient presenting with abdominal pain to emergency department was diagnosed to have an ovarian mass filling the Douglas space. At laparoscopy, the origin of the mass was identified as the posterior vaginal wall. After vaginal excision of the gelatinous mass, pathologic diagnosis revealed a rare tumor, LGFMS. We discussed the differential diagnosis of vaginal LGFMS.
