 A 35-year-old woman was referred because of a 3-month history of diarrhea and hematochezia. On admission, physical examination revealed tenderness in the lower abdomen. Laboratory results were significant for a C-reactive protein level of 0.34 mg/dl and an erythrocyte sedimentation rate of 39 mm/hr. IgG antibodies were positive for Chlamydia trachomatis. Colonoscopy and barium enema examination demonstrated numerous nodular lesions spreading over the rectum. The mucosa above the sigmoid colon appeared normal. Rectal-biopsy specimens showed hyperplasia of the lymphoid follicles and diffuse infiltration of inflammatory cells. The DNA of Chlamydia trachomatis was determined from rectal specimens by polymerase chain reaction. The patient was treated with minocycline hydrochloride, after which she became asymptomatic. We reviewed seven cases of Chlamydia trachomatis proctitis in the Japanese literature. We conclude that gastroenterologists should be aware of Chlamydia trachomatis proctitis and include it in the differential diagnosis of inflamed rectal mucosa showing numerous nodular lesions.
