Study Notes

Acne Variants

Acne fulminans: Severe variant primarily affecting adolescent males (ages 13-22). Characterized by painful, ulcerative nodules, systemic symptoms may include fever and weight loss. Treatment involves oral steroids, antibiotics, and isotretinoin.
Acne conglobata: A severe form of nodulocystic acne without systemic manifestations. Associated with conditions like dissecting cellulitis of the scalp and hidradenitis suppurativa.
Neonatal acne: Affects about 20% of newborns, appearing around 2 weeks and typically resolving by 3 months. Small papulopustules located on face and eyelids.
Infantile acne: Occurs between 3-12 months with notable comedo formation. Linked to androgen production and usually resolves by 1-2 years.
Acne excoriée: Common in young women, characterized by self-excoriated lesions leading to crusted erosions, often related to anxiety or body dysmorphic disorder. Treatment includes antidepressants and psychotherapy.
Drug-induced acne: Presents as inflammatory papules and pustules due to medication exposure.
Occupational acne: Results from exposure to follicle-occluding substances, with comedones as the dominant feature in affected individuals.

Treatment Overview

Topical treatments include retinoids (tretinoin, adapalene, tazarotene) which normalize follicular keratinization and demonstrate anti-inflammatory properties.

Key Characteristics of Acne

Chronic inflammatory condition of the pilosebaceous unit, presents with comedones, papules, pustules, cysts, and potential scarring.
Multifactorial disorder with significant psychological and economic consequences.

Epidemiology

Peak incidence occurs during adolescence, impacting around 85% of individuals between 12 and 24 years.
Acne can persist into adulthood, affecting 26% of women and 12% of men in their 40s.

Pathogenesis

Multifactorial origins include:
- Follicular hyperkeratinization
- Hormonal influences
- Inflammation mediated by Propionibacterium acnes
Genetic predisposition linked to sebaceous gland characteristics, with a high prevalence in identical twins.

Microcomedo Formation

The microcomedo is the precursor to all acne lesions, forming within the follicle.
Characterized by excess keratinocyte proliferation and corneocyte cohesiveness leading to hyperkeratotic plugs, with interleukin-1α potentially playing a role in its development.
