Terbinafine-Induced Acute Generalized Exanthematous Pustulosis.

Severe cutaneous adverse drug reactions are uncommon but potentially critical clinical situations demanding prompt diagnosis and treatment. We report a rare and severe case of terbinafine-induced acute generalized pustulosis. The patient was directly referred to a Burn Unit where she underwent diagnostic confirmation, systemic supportive care, and wound care treatments. Clinical and histopathological differential diagnosis of severe cutaneous adverse drug reactions is fundamental due to their significantly different management and prognosis.
