ABSTRACT
Endometriosis is defined as the presence and growth of endometrial tissue implants, outside the uterine cavity. It is in a episiotomy scar endometriosis that is extremely rare but can lead to significant morbidity in patients due to local infiltration. This condition usually presents with a clinical triad of history of episiotomy, tender nodule at the scar site, and cyclical pain. Here, we report one such rare case of episiotomy scar endometriosis in the perineum of a 30-year-old young female (P1L1) who presented with swelling and pain in the perineal region. The clinical examination and ultrasonography corroborate with the diagnosis of episiotomy scar endometriosis. Excision was done and histopathological examination confirmed the diagnosis. Episiotomy scar endometriosis should always be kept in the differential diagnosis when a lady presents with painful perineal swelling which increases during menstruation. Wide local excision is the treatment of choice and confirmation of the lesion can be done with histopathological examination. If the lesion is not diagnosed within a stipulated period of time, can progress with the involvement of the anal sphincters, and may also turn into a malignant lesion.
