[Chloroquine-induced isolated palatal hyperpigmentation].

We report about an isolated slate-greyish discoloration of the palatinum during chloroquine therapy of cutaneous lupus erythematosus of a 28-year-old woman. The hyperpigmentation is harmless. It is due to increased melanin synthesis and not due to deposition of the drug or its metabolites. The oculist should be consulted however, to exclude possible retinopathia.
