Perineal endometriosis with anal sphincter involvement

ABSTRACT

Perineal endometriosis is a rare complication of episiotomy. This is a case of a 44-year old woman with cyclic perineal pain and a history of episiotomy. A wedge biopsy of the perineal mass confirmed the diagnosis of endometriosis. Awareness of the occurrence of this rare type of extrapelvic pain during menses secondary to perineal cudometriosis is important.
