Idiopathic guttate hypomelanosis is a commonly acquired, benign leukoderma characterized by multiple, discrete round or oval, porcelain-white macules on sun-exposed areas, especially the extensor aspect of forearms and shins, sparing the face, neck, and trunk. It usually affects the geriatric population (>50 years); chronic exposure to ultraviolet rays and senile degeneration being the important pathogenic factors. The diagnosis remains essentially clinical, whereas newer confirmatory investigations are emerging. Despite the benign course of progression, many patients seek medical attention owing to cosmetic concerns. Several treatment modalities have been tried over time including topical, physical, and surgical measures, although there is lack of a standard treatment regime. In this article, we have reviewed the different aspects of this condition including treatment, along with the recent updates to create awareness about this dermatological entity.
