Abstract
Endometriosis is defined as the presence of ectopic endometrial tissue outside the
uterine cavity. It is a benign condition commonly observed in women of the reproductive
age group. It can occur in both pelvic and extra-pelvic sites. Moreover, pelvic endometriosis
is relatively common, as compared to extra-pelvic endometriosis. The most frequent
site for pelvic endometriosis is ovary. It can also affect rectum, uterosacral ligaments,
rectovaginal septum, urinary bladder. Extra-pelvic endometriosis is rare and when
it occurs, does so more frequently in surgical scar sites, especially in caesarean
section scar. Endometriosis in an episiotomy scar is extremely rare but can lead to
significant morbidity in patients due to local infiltration. This condition can be
diagnosed by the presence of the classical clinical triad of history of episiotomy,
tender nodule at the scar site and cyclical pain. Magnetic resonance imaging (MRI)
is a very useful imaging modality to diagnose and assess the deeper extension of the
lesion. Herein, we report one such case of episiotomy scar endometriosis in the perineum.
