The boy, who had been receiving carbamazepine [Tegretol] and risperidone [Risperdal] for 2 years for insomnia and mood swings, was referred with bilateral buccal mucosal and tongue lesion, which had lasted for > 1 year.

The ulcers corresponded with the occlusal planes, suggesting a Koebner phenomenon. There was also a predominantly reticular lesion on his lower labia mucosa. Differential diagnoses included oral lichen planus or an oral mucosal lichenoid reaction.

Lichenoid drug eruptions: case reportA 15-year-old boy developed oral lichenoid drug

eruption [OLDE] during treatment with carbamazepine andrisperidone [dosages not stated].
