Effects of mesalazine enemas on lymphoid follicular proctitis


Zhipeng Liu, Silin Huang, Zhengyu Chen, Xinying Wang,

Lymphoid follicular proctitis (LFP) is an uncommon inflammatory disease that is characterized by rectal bleeding, congested and granular mucosa without ulceration and abnormal and coalescing hyperplastic lymphoid follicles without acute inflammatory changes. The lesions are usually confined to the rectal mucosa. LFP therapy is not well defined. Herein, we present a case of LFP that was resolved with a rapid administration of mesalazine enemas. A 35-year-old male was admitted to our hospital due to intermittent rectal bleeding associated with stools. Total colonoscopy revealed nodular mucosa with top pinpoint-like ulcers from the rectum to the border between the sigmoid flexure and the rectum. The nodules congested together on the lower rectal segment and occupied 2/3 of the rectal lumina. Endoscopic submucosal dissection was performed in order to obtain more specimens for histologic examination, which revealed marked lymphoid follicular hyperplasia with prominent germinal centers and a conserved mantle zone. Treatment was started with mesalazine enemas of 4 g q.d. and the patient was asymptomatic after three days. All the lesions disappeared two months later. Mesalazine enemas could be a promising and effective therapeutic option for LFP therapy.
