Lymphogranuloma Venereum-Associated Proctitis Mimicking a Malignant Rectal Neoplasia: Searching for Diagnosis

Case series of perianal and pelvic MRI imaging findings in monkeypox

Monkeypox is a viral infection historically rarely seen in humans, but currently the focus of international attention due to a multi-country outbreak outside endemic countries of Central and West Africa, where cases are typically confined. Perianal pain and lesions have recently been recognised as a feature of monkeypox. We present a case series of the imaging findings of patients with monkeypox, including active proctitis, anal canal inflammation, and perianal inflammation. The aim is to increase awareness of perianal and rectal monkeypox MRI imaging features during this current outbreak.

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.
