Abstract

Endometriosis is a common gynecological disease among reproductive-age women that can result in chronic pain, severely decreased quality of life, and infertility. We present a case of a 44-year-old female with a known history of endometriosis who presented with constipation, decreased appetite, iron deficiency anemia, and unintentional weight loss for 6 months. Investigation with colonoscopy discovered a partially-obstructing mass in her proximal rectum and no evidence of malignancy on biopsy. The mass was subsequently removed during a combined robotic-assisted total hysterectomy with bilateral salpingo-ophorectomy and low anterior resection with reanastomosis. Surgical pathology determined that the mass was consistent with endometriosis and no malignancy was identified. This case calls attention to a unique manifestation of endometriosis and highlights the importance of maintaining a broad differential diagnosis while utilizing a multidisciplinary team in the management of a rectal mass in reproductive-age women.
