Facial lentigo

Facial lentigo refers to a benign, acquired hyperpigmented macule or thin plaque occurring on the integumentary system of the face, most frequently presenting as a solar lentigo secondary to chronic ultraviolet radiation exposure Clinically, lesions appear as well-circumscribed, light-to-dark brown, round or irregular macules that persist independently of seasonal sunlight variations

It primarily affects older adults and individuals with fair skin types, though it can occur across diverse populations with significant cumulative photoaging or as part of rare genetic syndromes

Clinically, lesions appear as well-circumscribed, light-to-dark brown, round or irregular macules that persist independently of seasonal sunlight variations

Pathophysiologically, the condition is defined by localized epidermal hyperplasia with elongation of the rete ridges, marked basal layer hyperpigmentation, and increased melanin production with or without a slight, non-atypical proliferation of basal melanocytes
