Appendiceal fecalith misdiagnosed as cecal stromal tumor: don't fall into the trap

A 30-year-old man presented with a 2-day history of hematochezia and a 4-year history of intermittent abdominal pain. Computed tomography scan revealed a low-density mass with central calcification in the cecum ([Fig. 1] a). Colonoscopy showed a 15×15 mm cecal mass with a superficial ulcer ([Fig. 1] b). A cecal submucosal tumor was considered. The surgeon recommended ileocecectomy or partial cecectomy. The patient was afraid of surgery and was transferred to our department.
