Universal Maculopapular Rash, an Unusual Presentation of Influenza in Children: A Case Report

Abstract

Introduction: Influenza is a viral infection that most commonly affects the upper respiratory tract; however, it may also involve other organ systems, including the heart, parotid glands, and skin. The dermatologic manifestations of influenza have not been well characterized, and physicians are often unfamiliar with them. Case Presentation: This case report describes a nine-year-old girl with influenza type B who presented with prolonged fever and a generalized measles-like maculopapular rash involving the face, trunk, and extremities, including the palms and soles. The patient developed bicytopenia but recovered with oral antihistamines alone, without antibiotic or antiviral therapy. This case highlights the pattern of dermatologic involvement in pediatric patients with influenza. Conclusions: Influenza virus infection may present with a maculopapular rash that can be mistaken for other conditions, such as measles or rubella. These lesions are self-limited, and only symptomatic treatment is recommended.
