A 71-year-old female with a history of endometrial cancer presented to our hospital with bilateral lower quadrant abdominal pain, which had been worsening over the past two months. he pain was associated with constipation, pencil-thin stools, and a 60 lb weight loss. On physical examination, the patient had suprapubic and let lower quadrant abdominal tenderness. Contrast-enhanced CT scan revealed a 6 cm pelvic mass in the let lower quadrant. It was unclear if this mass was arising from the sigmoid colon or abutting it. A colonoscopy to further investigate the mass was pursued and this revealed a moderate 5 cm long stenosis in the sigmoid colon starting at 15 cm from the anal verge. he stenosis was not ulcerated but had a bluish/purplish hue to it circumferentially. Multiple biopsies were obtained from that area and these revealed architectural changes with mild ibrosis but no malignancy. he mass was further explored with CT-guided ine needle aspiration. he results obtained were positive for cytokeratin-7, CA-125, estrogen receptor protein, and PAX-8 conirming that the mass was endometrial in origin. 1. Introduction Endometrial cancer is the leading cause of genitourinary cancers among women in the United States [1]. In general, if diagnosed early, it has a favorable prognosis. he ive- year survival for stage I disease is approximately 80 to 90 percent, for stage II it is 70 to 80 percent, and for stages III and IV it is 20 to 60 percent [2]. Recurrence rates are relatively low, with the majority of cases recurring within three years ater treatment. Around 77% of recurrences are associated with symptoms related to the site of recurrence [3]. Recurrence sites are evenly distributed between vaginal vault and distant metastasis (lung or abdominal) [3]. Signs or symptoms suggestive of recurrence include vaginal bleeding, abdominal or pelvic pain, persistent cough, or unexplained weight loss. Hence, in females with a history of gynecological cancers, including endometrial cancer, it is important to maintain an index of suspicion for recurrence when they present with such symptoms [3, 4]. 2. Case Report A 71-year-old Caucasian woman, with a remote history of stage 1 endometrial cancer treated more than 10 years ago with total abdominal hysterectomy and bilateral oophorec- tomy (TAHBSO) with no radiation, presented to our institu- tion with intermittent cramping and bilateral lower quadrant abdominal pain, progressively worsening over a 2-month period. his was associated with constipation and thin stools. She also reported a 60 lb weight loss over the past year. She denied any nausea, vomiting, hematochezia, or melena. She also denied fevers, chills, or night sweats. Physical examination revealed a tender abdomen mainly over the suprapubic area and the let lower quadrant. No guarding or rebound tenderness was appreciated. Bowel sounds were normoactive. A CT scan was performed and showed a 6 cm pelvic mass in the let lower quadrant(Figure 1(a)). It was unclear if this mass was arising from the sigmoid colon or abutting it. A colonoscopy was pursued to further evaluate the patient’s symptoms and investigate the radiographic indings. here was a moderate stenotic area measuring 5 cm in length in the sigmoid colon starting at 15 cm from the anal verge. his area was easily traversed with an adult colonoscope. he stenosis was not ulcerated but had a bluish/purplish hue to it circumferentially (Figures 1(b) and 1(c)) suspicious for malignant iniltration or extrinsic compression. Multiple biopsies were obtained from that area and these revealed Hindawi Publishing Corporation Case Reports in Gastrointestinal Medicine Volume 2015, Article ID 593786, 3 pages http://dx.doi.org/10.1155/2015/593786
