## Abstract

Systemic viral infections have been implicated as possible triggers for Lichen planus. An association of Lichen planus with dengue infection is exceptionally rare. We report a case of 38‐year‐old male who developed Lichen planus after the onset of dengue fever without any prior history or family history of Lichen planus. This case underscores the potential for dengue virus to act as a precipitating factor for Lichen planus, emphasizing the importance of identifying and managing the condition in clinical settings.
