A case of sarcoidosis of the rectum that developed in the lower part of the rectum is reported. The patient was a 64-year-old female who presented with malaise in the anal region. Digital examination of the anus and rectum, transanal ultrasonography and computed tomography of the pelvic cavity revealed a tumor with a size of approximately 3.0×4.0cm at the lower rectum. To make a definite diagnosis, an ultrasonography-guided needle biopsy was performed and the results strongly suggested sarcoidosis, which is a systemic disorder of unknown cause that rarely develops at the rectum.
Subsequent general examinations including Ga scintigraphy and computed tomography of the chest revealed abnormal density at the anterior superior mediastinum. The patient is currently under observation while undergoing detailed examinations.
