Dermoscopy to distinguish idiopathic guttate hypomelanosis from guttate lichen sclerosus flare
Guttate lichen sclerosus (LS), a rare variant of extragenital LS, is an inflammatory disorder classically presenting with whitish patches and nodules coalescing into plaques. Idiopathic guttate hypomelanosis (IGH) is a benign, typically asymptomatic idiopathic leukoderma that presents with multiple...

| Summary: | Guttate lichen sclerosus (LS), a rare variant of extragenital LS, is an inflammatory disorder classically presenting with whitish patches and nodules coalescing into plaques. Idiopathic guttate hypomelanosis (IGH) is a benign, typically asymptomatic idiopathic leukoderma that presents with multiple round or oval porcelain-white macules on sun-exposed areas, especially the forearm extensor surface and shins. In this study, we report a case of IGH mimicking guttate LS in a patient, highlighting the importance of dermoscopic evaluation in the diagnosis of hypopigmented skin lesions in patients with skin of color. |
