[Lichen nitidus in a young man on antiepileptic therapy].

We report the case of a 22-year-old man who developed multiple flesh-colored papules during antiepileptic treatment with lamotrigine. Histopathological examination confirmed the diagnosis of lichen nitidus, showing a sharply demarcated lymphohistiocytic infiltrate in a typical "ball-and-claw" configuration. Despite discontinuation of lamotrigine, the lesions persisted, while topical corticosteroid therapy resulted in moderate improvement. This case highlights a rare possible association between lamotrigine and lichen nitidus and contributes to the discussion of drug-induced lichenoid dermatoses.
