Perineal Endometriosis

ABSTRACT

Endometriosis is an enigmatic disease of menstruating females affecting the reproductive life. We report herein a case of perineal endometriosis in a 33-year-old woman. The patient presented two rounded, thickened plaques bilaterally on the perineum for about four year. The plaque on the right side was located mainly at the episiotomy scar. Histologic examination showed confirmative feature of glandular structures embedded in the cellular stroma and predecidual changes of late secretory phase of endometrium. Radical operation of total hysterectomy with bilateral oophorectomy and partial excision of perineal lesions were performed. There was complete resolution with no relapse by the 6-month follow-up. This is of a very rare occurrence and three cases have been reported in the Korean literatures up to date.
