[Segmental chlamydia proctitis].

A case report is given of a 28 year old homosexual suffering from segmental proctitis caused by Chlamydia. The patient had watery diarrhea and fever since 3 weeks. Stool specimen testing was negative in regard to Salmonella, Shigella and worm eggs. Infection with N. gonorrhoea, Herpes simplex virus, Toxoplasma gondi, Yersinia and M. tuberculosis could be excluded. Serological testing yielded results suggestive of an old lues infection successfully treated. On histological examination typical reticulocytary suppurating granuloma were found. Therapy of choice of Chlamydia-proctitis is tetracyclines.
