Abstract

Introduction: Endometriosis is a chronic disease with the presence of endometrium-like tissue containing endometrial glands and stroma outside the uterus. The incidence of episiotomy scar endometriosis after vaginal delivery is 0.06-0.7%. Case presentation: A 28-year-old parous woman with two previous vaginal deliveries with episiotomy presented to the outpatient department with severe pain and swelling in the perineal region over the past year, leading to difficulty in sitting, coitus and routine essential activities like defecation. She had undergone local perineal nodule excision surgery twice, which confirmed her perineal scar endometriosis diagnosis one year earlier at another hospital with no improvement in symptoms. Physical examination revealed a firm, tender, deeply embedded palpable nodule measuring approximately 3 - 4 cm in the left posterolateral aspect of the distal vagina. Wide local excision of the nodule with a clear margin of 1 cm was performed. The nodule extended up to the left ischial tuberosity and apex up to the pudendal vessels complex. Discussion: The classic diagnostic triad of perineal endometriosis were present in this patient. Surgical intervention with wide local excision with a clear margin of approximately 1 cm of healthy tissue reduces the chance of recurrence. Conclusion: Awareness of this condition among medical practitioners will lead to early diagnosis and excision. Timely intervention in the form of excision with free margins is the definitive treatment and provides complete pain relief and good quality of life for endometriosis patients.
