There is a possibility that it could be peripapillary keratosis.
Keratosis pilaris is a chronic keratotic skin disease of the hair follicles, often on the arms and front of the thighs, with a symmetrical distribution. The affected area has a peculiar roughness to the skin, with pinpoint to corn-sized papules at the pores that are the same colour as the skin and are tipped with light brown keratinous plugs containing curly hairs. Small funnel-shaped depressions are left after the plugs are peeled away, but new plugs soon appear again.
The disease is often asymptomatic, sometimes slightly itchy, heavy in winter and mild in summer.
Prompt medical attention is recommended if a definitive diagnosis is desired.
