WHEN VIRUSES MEET DERMATITIS: A CASE REPORT OF MOLLUSCUM CONTAGIOSUM TRIGGERING ATOPIC DERMATITIS.

Molluscum contagiosum (MC) is a common viral skin infection in children, caused by a poxvirus. Atopic dermatitis (AD) is a chronic inammatory skin condition characterized by impaired skin barrier function and immune dysregulation, which predisposes individuals to infections like MC. However, cases where MC acts as a trigger for AD ares are less frequently reported and present unique clinical challenges. We describe a 9-year-old boy with a past history of mild AD who presented with multiple umbilicated papules consistent with MC, surrounded by inamed, eczematous plaques. The temporal association of AD exacerbation with the spread of MC lesions suggested a reactive process consistent with Meyerson's phenomenon. Additionally, hypersensitivity responses such as id reactions can mimic or exacerbate eczematous eruptions, complicating diagnosis and management. This case highlights the bidirectional relationship between MC and AD. While AD increases susceptibility to MC, the viral infection itself may provoke immune-mediated ares of dermatitis. Understanding this interplay is crucial, as aggressive treatment of one condition may worsen the other. A conservative, well-balanced therapeutic approach is essential to minimize symptom escalation. This case underscores the importance of clinical awareness and further investigation into the immunologic mechanisms linking viral infections and chronic dermatoses to improve patient outcomes.
