Answer

Keratosis pilaris (KP) is overall a very common condition and is present worldwide. Keratosis pilaris affects 50-80% of adolescents and approximately 40% of adults worldwide.

In India and other countries, a specific condition called erythromelanosis follicularis faciei et colli is described. This is an unusual condition with a possible genetic or other relationship to keratosis pilaris. Erythromelanosis follicularis faciei et colli is characterized by the triad of hyperpigmentation, follicular plugging, and erythema of the face and neck. [8, 9]
