Benign mixed tumor of the vagina.

Mixed tumor of the vagina is a rare benign tumor containing both epithelial and mesenchymal components. The authors report the case of a 35-year-old woman who presented with a painless mass that had descended from the vagina in the last six months. Physical examination showed the presence of a solitary, non-tender nodule that was 3x3x2 cm in size and seemed to originate from the posterior wall of the lower vagina. The tumor was removed and pathologically examined. The findings were indicative of a mixed tumor of the vagina, and were in agreement with previous cases. No recurrence or progression occurred during the ten-month follow-up. As this tumor shares common features with some other tumors, its differential diagnosis is very important. Moreover, due to the rarity of this disease, gynecologists and pathologists need to familiarize themselves with the features in order to avoid a misdiagnosis.
