title: Chloroquine-induced hypopigmentation of hair and freckles. Association with congenital renal failure.
abstract: Hypopigmentation of hair and freckles occurred in a patient receiving chloroquine sulfate therapy. This patient had a severe congenital renal failure that presumably increased plasma and tissue levels of the drug substantially, accounting for the hypopigmentation.
