title: Enlarging perineal endometrioma developing after colpoperineorrhaphy.
abstract: Although endometriosis is not infrequent, the occurrence of perineal endometriomata is relatively rare and is generally attributed to seeding of endometrial cells to the perineal body during obstetrical trauma. A 45-year-old female with a history of a colpoperineorrhaphy during menses and a remote history of obstetric perineal trauma presented with an enlarging perineal mass. Excision of the mass led to a clinical and histopathologic diagnosis of perineal endometriosis. Elective surgery disrupting the vaginoperineal epithelium performed during menses may facilitate the seeding of endometrial cells to the perineal body and formation of perineal endometriomata.
