Abstract

Introduction: Perineal endometriosis is a rare entity which can be explained by direct implantation of endometriotic cells over the fresh episiotomy wound and subsequent development of scar endometriosis. 

Case Report: Present patient presented with pain at episiotomy site which is associated with menstruation. Examination during menstruation revealed reddish brown spots with blood oozing from the spots. Clinical diagnosis was confirmed by FNAC. Mass excised and sent for histopathological examination.

Conclusion: Although diagnosis essentially remains clinical, preoperative evaluation with FNAC and endo-anal ultrasound can be performed. Wide local excision remains treatment of choice and follow up for recurrence is recommended. Histopathological examination is obligatory to exclude rare possibility of malignant changes.
