What is the pathogenesis of acne?

The major pathogenic factors involved are hyperkeratinization, obstruction of sebaceous follicles resulting from abnormal keratinization of the infundibular epithelium, stimulation of sebaceous gland secretion by androgens, and microbial colonization of pilosebaceous units by Propionibacterium acnes, which promotes …

What is the diagnosis of acne vulgaris?

Acne vulgaris may be defined as any disorder of the skin whose initial pathology is the microscopic microcomedo. 3 The microcomedo may evolve into visible open comedones (“blackheads”) or closed comedones (“whiteheads”). Subsequently, inflammatory papules, pustules, and nodules may develop.

What are causes of acne vulgaris?

Acne, also known as acne vulgaris, is thought to be caused by multiple factors. Overproduction of a normal oil on the skin, called sebum, increases under the influence of hormones. This, coupled with insufficient shedding of exfoliating dead skin cells, plugs hair follicles.
