Villous adenoma of the cecum

Villous adenoma of the cecum developed in a 49-year-old man; the diagnosis was confirmed at operation. The pathologic and radiologic features of villous tumour in this location differ from those of tumours situated in the sigmoid colon and rectum. Signs and symptoms are vague; bleeding per rectum may not occur. Right hemicolectomy is recommended because of the high malignant potential of this tumour.
