Endometrioma of the perineum associated with episiotomy scars.
Two cases of endometrioma occurring in the perineum, associated with episiotomy scars and involving the external anal sphincter are described. Previous similar cases in the literature are reviewed and discussed. Misdiagnosis of this uncommon lesion is the rule when it is seen outside gynaecological practice. If, however, its existence is appreciated then correct diagnosis is simple and treatment is straight forward.
