Abstract
Malignant degeneration of endometriosis is a very rare event, especially when it develops in an episiotomy scar. A 53-year-old woman with an enlarged perineal mass presented to the hospital. She had undergone vaginal delivery with episiotomy twice. Imaging analyses showed a mass involving the levator ani muscle apart from the rectum, with lymph node metastases to the right inguinal and internal iliac regions. A biopsy specimen of the right inguinal lymph node revealed poorly differentiated adenocarcinoma. She underwent neoadjuvant chemotherapy according to the treatment strategy of anal fistula cancer. Laparoscopic posterior pelvic exenteration and pelvic lymph node dissection with anterior inguinal node dissection was performed, along with perineal reconstruction. Pathological examination revealed clear cell adenocarcinoma with lymph node metastases, derived from extrapelvic endometriosis in the episiotomy scar. She was treated with adjuvant chemotherapy according to the treatment strategy of vulvar cancer, and showed no evidence of recurrence after 15 months of surgery.
