Challenges in Diagnostic of the Ulcerative Rectitis by Lymphogranuloma venereum in Chlamydia trachomatis Infection and AIDS

Lymphogranuloma venereum is a rare manifestation of Chlamydia trachomatis infection and may manifest with anorectal symptoms, rectitis, proctitis, and inguinal masses. The new outbreaks of Chlamydia infection have allowed the description of new cases with rectal symptoms (rectitis/proctitis), mainly in people living with HIV and men who have sex with men. The authors present the clinical findings in people living with HIV men who have sex with men with lymphogranuloma venereum with ulcerative rectitis identified by colonoscopy. Differentiation of proctitis was made from other causes of sexually transmitted infections, such as gonorrhea and herpes virus, inflammatory diseases (Crohn's disease), and neoplastic and opportunistic infections such as cytomegalovirus, tuberculosis, and histoplasmosis. The symptoms of the patient and the endoscopic lesions were suspected of lymphogranuloma venereum with ulcerative proctitis, which was confirmed by biopsy and performing the polymerase chain reaction. After appropriate treatment with doxycycline, the patient evolved favorably.
