Figure 1 Adenoma of the Sigmoid Colon.

A screening barium enema in a 78-year-old man with a positive test for fecal occult blood showed a flat round mass with a surrounding hump (Panel A, arrows). Panel B is an endoscopic view of the lesion. Sigmoidectomy was performed without complication. The resected fresh specimen, which measured 3.8 by 2.4 cm, is shown in Panel C. Panel D shows the longitudinal cut surface of the lesion (hematoxylin-eosin stain). No carcinomatous focus was found. The patient is well two years after surgery.
