Solar lentigines

Solar lentigines are common, benign cutaneous hyperpigmentations that arise from chronic exposure to ultraviolet radiation, representing a hallmark of photoaging

Solar lentigines are common, benign cutaneous hyperpigmentations that arise from chronic exposure to ultraviolet radiation, representing a hallmark of photoaging Typically affecting fair-skinned adults and older populations, these lesions most frequently develop on chronically sun-exposed areas such as the face, dorsum of the hands, forearms, and upper trunk

Typically affecting fair-skinned adults and older populations, these lesions most frequently develop on chronically sun-exposed areas such as the face, dorsum of the hands, forearms, and upper trunk Clinically, they present as well-circumscribed, asymptomatic, light-brown to dark-brown macules or small patches that persist independently of seasonal sun variations

Clinically, they present as well-circumscribed, asymptomatic, light-brown to dark-brown macules or small patches that persist independently of seasonal sun variations

Pathophysiologically, they are characterized by epidermal hyperplasia, elongation of rete ridges, localized proliferation of non-atypical melanocytes, and increased melanin deposition within basal keratinocytes
