This case report studied colorectal endometriosis with lymph node involvement in a 40-year-old woman presenting with cyclic abdominal pain and progressive constipation, whose retosigmoidoscopy showed a stenotic rectosigmoid lesion 14 cm from the anal verge. She underwent retosigmoidectomy, and histopathology showed endometrial glands and fibrosis in the bowel wall with endometrial cells identified in mesocolic lymph nodes; the patient recovered without complications and was discharged on postoperative day 6. The authors emphasize that lymphatic dissemination in colorectal endometriosis is extremely rare and, based on their literature review, represented the fifth reported case, with an explicit limitation that it is derived from a small number of published reports rather than systematic evidence. This paper is centrally about endometriosis — specifically lymphatic dissemination evidenced by mesocolic lymph node involvement in colorectal endometriosis.

Abstract

A 40-year-old female patient presented abdominal pain during her periods and progressing constipation during the last 6 years. Retosigmoidoscopy showed a stenotic lesion 14cm above the anal verge. The patient underwent a retosigmoidectomy and the specimen was sent to histopathologic exam. The diagnose was endometriosis with the involvement of the colon and rectum, associated with dissemination of the endometrial cells by the lymph nodes. The patient recovered well and was discharged on the 6th postoperative day. It is commented on the rarity of the lymphatic dissemination in these cases and according to the reviewed literature, this is the 5th case reported. Thus, dissemination of the disease to extra-abdominal sites could possibly occur by this route. Therefore, pathologists should carefully exam the lymph nodes of the mesocolon in these specimens because findings of endometrial "metastasis" may be present.
