title: Colonic sarcoidosis presenting multiple submucosal tumor-like lesions.
abstract: Here, we describe a case of colonic sarcoidosis that developed over a 7-year period of observation of intrathoracic sarcoidosis. The patient was asymptomatic, but colonoscopy showed multiple elevated lesions mimicking submucosal tumors in several areas of the colon. The specimens obtained by biopsy showed noncaseating granuloma, suggesting sarcoidosis. The observations in the present case indicate that colonic involvement should be considered in patients with sarcoidosis. Furthermore, the macroscopic appearance of multiple submucosal tumor-like lesions in colonic sarcoidosis is extremely rare.
