Application of rubber band and clip traction for removal of a submucosal fecalith mimicking a submucosal tumor of the appendix under colonoscopy.

The term “submucosal tumors” generally refers to colorectal uplifted lesions with a complete upper mucosal cortex, including lipomas, stromal tumors, lymphomas, and neuroendocrine tumors [1]. Approximately 13 % of gastrointestinal submucosal tumors are malignant. Endoscopic ultrasonography (EUS) is the first choice of modality for the diagnosis of submucosal tumors [2]. Here we report an unusual case of a submucosal fecalith mimicking a submucosal tumor of the appendix.
