These female patients developed hyper pigmentation of the skin, largely on the exposed parts of the body. The pigmentary changes varied from brownish/ grayish/ bluish-black in color, patchy or diffuse, intense or mild. The shortest time lag between onset of chloroquine therapy and development of pigmentary changes was 3 months. The patients should be informed about this cosmetically important toxic effect of chloroquine and advised to avoid direct exposure to sunlight.
