Cytomegalovirus Associated Enterocolitis and Skin Eruption: A Pediatric Case Misdiagnosed as Acute Appendicitis

We present a case of an immunocompetent 2-year-old boy, with cytomegalovirus-associated enterocolitis and petechial skin eruption, initially misdiagnosed as acute appendicitis. Despite abdominal pain, diarrhea and a rash for 15 days, diagnostic laparoscopy revealed no surgical pathology. Dermatological examination identified perifollicular petechiae, leading to a diagnosis of cytomegalovirus infection, which was confirmed by serology. This case emphasizes the importance of considering viral infections in pediatric patients with gastrointestinal and dermatological symptoms. It also highlights the diagnostic value of cutaneous findings in cytomegalovirus infection.
