Clinical and dermoscopic analysis of 32 cases of acquired facial hyperpigmented macules

1

Acquired facial hyperpigmented macules (AFHM) are light brown, asymptomatic macules primarily found on the foreheads and temples of young children.
2

Dermoscopic features of AFHM include light brown pseudoreticular pigmentation and linear/branching vessels, aiding in diagnosis.
3

The study involved 32 pediatric cases, with a follow-up showing 96.4% of patients experienced complete lesion disappearance.
4

AFHM typically presents in infancy, with most cases occurring between 1 to 15 months of age and improving with sun protection.
5

The etiology of AFHM remains unclear, but ultraviolet radiation is hypothesized to play a significant role in its pathogenesis.
