Idiopathic Guttate Hypomelanosis (IGH) is a benign and asymptomatic skin manifestation characterized as diffuse hypopigmented macules, or white spots. The size of the lesions varies from 1-10mm, but are most commonly 1-3 mm in diameter. It is most commonly seen in fair-skinned individuals and appears to be related to cumulative sun exposure rather than just age. Interestingly, this condition manifests in women earlier than men, probably because their legs are more exposed. However, as age increases the incidence of IGH in women and in men is the same. IGH can also be seen in older dark-skinned individuals, but usually at more advanced age. The distribution of IGH can be seen along most exposed areas of the body. These include areas of the arms, legs, upper back, and face. Lesions are usually seen first along the anterior portion of the legs and then seen on the arms, back and face.
