A rare cecal subepithelial tumor.

QUESTION A 55-year-old male was referred to the coloproctology department by another hospital for resection of a cecal mass, which was found incidentally during screening colonoscopy. He had no clinical symptoms. He had undergone open repair of a right inguinal hernia 2 years prior to admission. Physical examination revealed no abnormal findings. Routine laboratory data and tumor markers on admission did not show any abnormal findings. Colonoscopy revealed a protruding mass with normal mucosa in the cecum (Figure 1a). It had raised borders and no stalk. Thus, a subepithelial tumor (SET) with external compression of the cecal wall was suspected. When we examined the SET with forceps, it was found to be non-movable and had a hard consistency (Figure 1b). Biopsies revealed the presence of normal colonic mucosa.
