  1. A patient presents with a tense subepidermal blister and linear IgG along the basement membrane on direct immunofluorescence. What is the diagnosis?

    Answer: Bullous pemphigoid

    Bullous pemphigoid shows tense subepidermal bullae with linear IgG and C3 at the dermoepidermal junction.

  2. Which antigens are targeted in bullous pemphigoid?

    Answer: BP180 and BP230

    Autoantibodies in bullous pemphigoid target hemidesmosomal proteins BP180 and BP230.

  3. Pemphigus vulgaris demonstrates which immunofluorescence pattern?

    Answer: Intercellular 'fishnet' IgG

    Pemphigus vulgaris shows intercellular 'chicken wire' or fishnet IgG deposition between keratinocytes.

  4. Dermatitis herpetiformis is associated with which systemic condition?

    Answer: Celiac disease

    Dermatitis herpetiformis is strongly linked to gluten-sensitive enteropathy (celiac disease).

  5. Which drug is first-line for dermatitis herpetiformis symptom control?

    Answer: Dapsone

    Dapsone rapidly relieves the intense pruritus of dermatitis herpetiformis.

  6. A positive Nikolsky sign indicates:

    Answer: Epidermal detachment with lateral pressure

    The Nikolsky sign is separation of the epidermis with tangential pressure, seen in pemphigus and TEN.

  7. Before starting dapsone, which laboratory test is essential to prevent hemolysis?

    Answer: G6PD level

    G6PD deficiency predisposes to dapsone-induced hemolytic anemia, so it must be checked first.
