✍️ Sample Dermatologist Certificate Questions & Answers
1. Which autoantibody is most specifically associated with pemphigus vulgaris?
Pemphigus vulgaris is caused by IgG antibodies against desmoglein 3, leading to acantholysis and suprabasal blisters.
2. A teenager presents with grouped erythematous papules and nodules along the jawline and perioral area. Which hormonal influence is most implicated?
Teenage acne along the jawline and lower face is driven by androgen-stimulated sebaceous gland hypertrophy and increased sebum production, particularly during puberty.
3. A patient taking methotrexate for psoriasis develops oral ulcers and cytopenias. Which supplement should be co-administered to reduce toxicity?
Folic acid supplementation reduces methotrexate-related side effects including mucositis and bone marrow suppression without significantly reducing efficacy.
4. What is the Breslow thickness threshold above which sentinel lymph node biopsy is routinely recommended for melanoma?
SLNB is routinely recommended for melanomas >1.0 mm Breslow thickness; it may be considered for 0.8–1.0 mm lesions with high-risk features.
5. What wood lamp finding is characteristic of erythrasma?
Erythrasma, caused by Corynebacterium minutissimum, produces coral-red fluorescence under Wood lamp due to porphyrins produced by the bacteria.
6. The Auspitz sign, elicited by removing a psoriatic scale and seeing pinpoint bleeding, reflects what underlying histological feature?
Auspitz sign results from the very thin suprapapillary plate in psoriasis; removing scale exposes the engorged capillary tips, causing punctate bleeding.
