Small cell carcinoma of the colon is a rare entity, comprising only 1.5% of all colon cancers. It is an aggressive neoplasm with rapid local progression and early metastasis. We present a case report of F-18 FDG PET/CT features of small cell carcinoma arising in the ascending colon of an 86-year-old woman who presented with anemia and melena. FDG PET/CT demonstrated a small, intense focus of FDG hypermetabolism in the cecum. Extrapulmonary small cell carcinoma, described in the salivary glands, pharynx, esophagus, stomach, small bowel, colon, rectum, gallbladder, uterus, kidney, and skin, has a poor prognosis when involving the gastrointestinal tract.
