Question: A 67-year-old man presented for routine health checkup. He did not have any specific gastrointestinal (GI) symptoms. On examination, his vital signs were normal and abdominal examination was unremarkable. Complete blood count showed a white blood cell count of 6300/ L, and a platelet count of 295,000/ L. Hemoglobin concentration was 15.1 g/dL. Hepatic enzymes, lipid profile, blood urea nitrogen, and creatinine levels were normal. Serum glucose was 119 mg/dL, but HbA1c level was normal. The chest radiograph and plain abdomen showed no abnormal findings. Colonoscopy was performed and several small polyps were found in the ascending and transverse colon. And a short pedunculated polypoid mass (15 mm long, 8 mm in diameter) was found in the sigmoid colon (Figure A). This lesion was covered with normal-appearing mucosa and the top was flat and slightly depressed. After polypectomy of polyps, the mass in sigmoid colon was also resected using snare (Figures B, C). What is the endoscopic and pathologic diagnosis?
