Oral lichenoid drug eruption: a report of a pediatric case and review of the literature.

Lichenoid drug eruptions are seen most frequently on the skin and seldomly affect the mucosal surfaces. Oral involvement-known as oral lichenoid drug eruption-is more common in the adult population and has been associated with numerous medications. Pediatric-onset oral lichenoid drug eruption is an exceptionally rare finding with only isolated cases published in the literature.
