Dermatology - Acneiform, Cornification, and Lichenoid Disorders
1. What is acne vulgaris?: - inflammation of pilosebaceous units
2. What are characteristic lesions of acne vulgaris?: - comedones
- papules
- pustules
- cysts
- nodules
3. What are the 4 stages of acne vulgaris?: From less severe to severe:
- blackheads
- whiteheads
- papules and pustules
- cysts and nodules
4. Who is acne vulgaris MC in?: MC in adolescents and young adults
5. What is the organism that causes acne vulgaris?: - Propionibacterium acnes
6. What are the 4 key elements that lead to acne vulgaris?: 1. sebum production
2. follicular epidermal hyperproliferation, which leads to plugging of the hair follicle
,3. Propionibacterium acnes
4. inflammation and immune response leads to acne vulgaris
7. What are RFs for acne vulgaris?: - parent with severe acne (genetics)
- endocrine disorders like PCOS (higher testosterone)
- medications (lithium, steroids, OCPs, anticonvulsants)
- emotional stress may exacerbate
- occlusion pressure on skin (leaning face on hands, helmet and sports gear, oil-based cosmetics)
8. What is the primary site for acne vulgaris and where does it spread to?: - Primary
site is FACE, then moves to the back, chest, and shoulders
9. What are the 2 categories of lesions with acne vulgaris?: Non-inflammatory
- comedones (open and closed)
Inflammatory
- papules
- pustules
- nodules
, 10. What is the difference between closed and open comedones?: Closed comedone
"whitehead"
- slightly raised tiny papule (1-3 mm)
- minimal erythema
- cream to white
- no clear opening
Open comedone "blackhead"
- flat or slightly raised (1-3 mm)
- dark oxidized center of keratin-lipid
- keratin may be expressed from site
11. What is mild acne vulgaris characterized by?: - LESS than half of the face involved
- T zone of the face involved
- NO nodules
- does NOT occur on a daily basis
- consists of non-inflamed open and closed comedones
12. What is moderate acne vulgaris characterized by?: - MORE than half of the face involved
- INCREASED number of MIXED lesions
- occasional nodule
- might involve chest/back
