Pigmentation related to drugs consist 10-20% of cases with acquired hyperpigmentation. Melasma is a common acquired disorder characterized by symmetric, hyperpigmented patches with an irregular outline, occurring most commonly on the face. Melasma is rarely seen in males. High ultraviolet exposure and family history are the most common in ethiology and some drugs may result melasma to be seen in males which is very rare. Phototoxic drug reaction should also be considered in differential diagnosis in male patients with hyperpigmentation on the sun exposed areas.
