Question 1: A 45-year-old woman presents with multiple, well-demarcated, erythematous plaques with silvery scales on the elbows and knees. What is the most likely diagnosis? A) Psoriasis vulgaris B) Eczema C) Tinea corporis D) Lichen planus Answer: A) Psoriasis vulgaris Explanation: The presentation described is characteristic of psoriasis vulgaris, which typically manifests as erythematous plaques covered with silvery scales, commonly affecting extensor surfaces like elbows and knees. Eczema tends to be more itchy with less well-defined plaques, tinea corporis usually presents with ring-shaped lesions with central clearing, and lichen planus has purple, polygonal, flat-topped papules. --- Question 2: Which of the following is the most common causative agent of atopic dermatitis? A) Staphylococcus aureus B) Herpes simplex virus C) Malassezia furfur D) Allergic contactant Answer: A) Staphylococcus aureus Explanation: While Staphylococcus aureus is a common colonizer and can exacerbate atopic dermatitis, the primary cause of atopic dermatitis is an allergic hypersensitivity reaction 3 involving environmental allergens and skin barrier dysfunction. However, bacterial superinfection with S. aureus is common in atopic dermatitis lesions, often complicating the condition. --- Strategies for Approaching MCQ Dermatology Questions Effective answering of MCQs involves a strategic approach.

She reports burning pain. What is the most likely diagnosis? A) Herpes simplex virus infection B) Impetigo C) Aphthous ulcer D) Contact dermatitis Answer: A) Herpes simplex virus infection Explanation: The presentation of grouped vesicles on erythema, especially involving the lips and oral mucosa, is characteristic of herpes labialis caused by HSV. The burning sensation further supports this. Impetigo typically presents as honey-colored crusted lesions, aphthous ulcers are painful but ulcerative, and contact dermatitis is usually eczematous rather than vesicular. --- Question 2: Which of the following is the most common cause of psoriasis? A) Bacterial infection B) Genetic predisposition C) Fungal overgrowth D) Autoimmune response Answer: D) Autoimmune response Explanation: Psoriasis is primarily an autoimmune disorder characterized by hyperproliferation of keratinocytes driven by immune dysregulation.
