Idiopathic guttate hypomelanosis (IGH) is a benign, typically asymptomatic, acquired leukoderma characteristically affecting mature individuals. Although the etiopathogenesis is unclear, chronic sun exposure and senile degeneration are important triggers. Researchers have been engaged in a continuous effort to unveil the gray areas encompassing different aspects of IGH pathogenesis. Read More

Dermoscopy has traditionally been used for the diagnosis of neoplasms and more recently in the evaluation of inflammatory conditions. Recent observational studies have suggested a role for dermoscopy in identifying and differentiating acquired pigmentary disorders. This comprehensive review will summarize the growing literature on the use of dermoscopy for pigmentary disorders. Read More

Background: Oxidative stress parameters have been reported to be significantly higher than controls in diverse disorders of pigmentation but no such data seem to be extant for IGH.

Objectives: To verify whether heightened oxidative stress levels are seen in patients with IGH (compared with matched controls) and quantify the same in blood using appropriate biochemical markers. Further, an attempt to determine if there might be any correlation between the amount of oxidative stress and the severity of the disease. Read More

One of the most frequent complaints in dermatology clinics is the eruption of hypopigmented patchy skin lesions. The aim of the study was to investigate the utility of dermoscopy in common hypopigmented macular diseases. Patients with the followings diseases were examined by dermoscopy: vitiligo, pityriasis alba, nevus depigmentosus, achromic pityriasis versicolor, idiopathic guttate hypomelanosis, and extragenital guttate lichen sclerosus.

Frontal fibrosing alopecia (FFA) is characterized by progressive band-like scarring alopecia involving the frontotemporal hairline and limbs and irreversible alopecia of the eyebrows. Two opposite types of pigmentary alterations have been reported in FFA: hyper- and hypopigmentation. Here, we report a 57-year-old Hispanic female with FFA who presented with peripilar hypopigmentation and idiopathic guttate hypomelanosis on the upper extremities. Read More

Acquired hypopigmented skin changes are commonly encountered by dermatologists. Although hypopigmentation is often asymptomatic and benign, occasional serious and disabling conditions present with cutaneous hypopigmentation. A thorough history and physical examination, centered on disease distribution and morphologic findings, can aid in delineating the causes of acquired hypopigmented disorders. Read More
