Colitis Cyatica Profunda: Case report / 대한소화기내시경학회지

Colitis Cystica Profunda(CCP) is an uncommon disease in Korea, and little knowledge exists about CCP, including knowledge about its incidence and prevalence. However, it may be speculated that the disease will be diagnosed more often due to advancement in diagnostic tool and growing interest. CCP is essentially the same disorder as Solitary Rectal Ulcer Syndrome(SRUS), but it has been reported separately because of its external appearances such as broad shaped polyps or nodules. Both CCP and SRUS are called MPS. Of importance is that a submucosal-cyst-containing lesion needs to be differentiated from mucus- producing adenocarcinoma. This differentiation is obvious from the CCP histologic features, such as fibromuscular obliteration of lamina propria and submucosal cysts. In light of these facts, it is important to obtain a sufficient biopsy specimen to examine accurately. It is not uncommon for CCP to be accampanied by rectal prolapse or incomplete intussusception, so diagnostic approaches of these associated disorders should be done at the same time. The authors have recently experienced one case of CCP associated with rectal prolapse. The case was treated effectively and is reported in this paper along with a review of the literature on this subject.

Lymphoid Polyp in the Rectum / 대한소화기내시경학회지

Lymphoid polyp is a rare disease in the colorectal area. It occurs commonly in the rectum. It is a nonepithelial benign tumor. Because of the benignancy of its nature, it has other names as well, such as benign lymphoma or rectal tonsil. A lymphoid polyp can be differentiated from a malignant lymphoma by the proliferation of normal lymphoid tissue which has a prominent follicular pattern and a clearly defined germinal center. A lymphoid polyp can regress spontaneousely without any treatment. There is no recurrence or malignant transformation. Recently, the authors experienced a case of lymphoid polyp in the rectum. We report a case of lymphoid polyp in the rectum diagnosed by piecemeal polypectomy.
