Anorectal manifestations of monkeypox are increasingly being recognized as a potentially serious complication. We present the case of an HIV-positive, tecovirimat-treated male presenting with monkeypox virus-associated severe proctitis with associated perianal pathology. Despite the use of antiviral agents and intravenous vaccinia immune globulin, the monkeypox-associated perianal lesions evolved into abscesses, requiring incision and drainage. This report highlights a multidisciplinary approach involving surgery for anorectal complications of monkeypox virus-associated proctitis and perianal lesions. Surgery may offer immediate relief and reduce the potential long-term morbidity associated with severe monkeypox virus-associated rectal and perianal manifestations refractory to available medical countermeasures.
