{Reference Type}: Case Reports {Title}: A Case of Herpes Simplex Virus Colitis in an Immunosuppressed Patient. {Author}: Tidwell J;Nguyen MTT;Forouhar F;Stewart CL;Bath R; {Journal}: Cureus {Volume}: 15 {Issue}: 12 {Year}: 2023 Dec 暂无{DOI}: 10.7759/cureus.51409 {Abstract}: Herpes simplex virus (HSV) can cause severe disseminated infections in immunocompromised patients. Gastrointestinal tract involvement seldom includes the colon. We present a rare case of disseminated cutaneous HSV infection with concomitant colonic involvement in an immunosuppressed patient. The patient's clinical presentation and computerized tomography (CT) findings were concerning for colitis. She failed to improve on antibiotic therapy and subsequently underwent flexible sigmoidoscopy. Gross findings and histopathology were consistent with herpes simplex virus colitis. It is essential to recognize this pathology in immunocompromised patients to evaluate the need to hold immunosuppressive therapy and ensure successful treatment to prevent fatal outcomes.
