Acquired facial telangiectatic hyperpigmented macular dermatosis (AFTHMD, also known as acquired facial hyperpigmented macules) is a rarely reported pigmentary condition characterized by light brown macules on the forehead and temples of infants and young children that develop without antecedent inflammation or trauma. The pigmentation is accompanied by capillary dilation and proliferation that is evident dermoscopically and histopathologically. In the reported cases, all races / ethnicities were seen; males were more frequently affected than females and the onset was typically noted at or under age 1 year.

While the pathogenesis of AFTHMD remains unclear, it has been proposed that the capillary dilation and proliferation may result from elevated VEGF levels. Other proposed mechanisms include induced pigmentation from ultraviolet (UV) and visible light exposure or increased dermal capillary shear stress from repetitive mechanical forces, such as crying, resulting in vascular endothelial damage and perivascular infiltration. 

The lesions typically self-resolve or fade within 1 year.
