Iraha, Kanemoto, and Hokama: All that elongates is not a polyp

Quiz

An 83-year-old woman with Sjögren syndrome presented to the emergency unit with acute painless hematochezia. Her physical examination revealed unremarkable findings. Laboratory investigations showed a white blood cell count of 7,600/μL, hemoglobin of 13.8 g/dL, and C-reactive protein of <0.1 mg/dL (reference range, <0.26 mg/dL). An enhanced abdominal computed tomography (CT) revealed an air bubble (arrow) and an extravasation (arrowhead) in the sigmoid colon (Fig. 1). The subsequent colonoscopy (Fig. 2) and narrow-band imaging (NBI) (Fig. 3) revealed a hemorrhagic lesion. What is the most likely diagnosis?
