Comedogenesis

  • C. Piérard-Franchimont

Abstract

Comedogenesis refers to the abnormal differentiation with excessive cornification of the follicular infundibulum that results in the formation of a horny plug called microcomedo [1]. Clinical comedones evolve from precomedones and microcomedones, the initial stage being visible only at the microscopic level. Among the distinct types of pilosebaceous units, both the sebaceous follicle and the vellus follicle are prone to comedogenesis. Such abnormality may affect a limited number of follicles, but it may also involve the vast majority of them in certain areas of the body.
