Keratosis pilaris, commonly known as "chicken skin," is a common follicular keratotic disorder characterized by keratotic follicular papules with varying degrees of perifollicular erythema.

In severe cases, it can also appear on the face, scapulae, forearms, and lower legs, with occasional generalized distribution.

View detailsPrickly heat
Prickly heat, also known as miliaria, is also referred to as heat rash or sweat rash. It is a common transient skin condition in summer, caused by hot and humid weather, excessive sweating, and impaired sweat excretion. The sweat ducts become blocked by keratin, leading to sweat extravasation that infiltrates and irritates the surrounding tissues, resulting in papules, papulovesicles, and vesicles at the sweat pores. Prickly heat generally resolves spontaneously after environmental ventilation and cooling.
