Pemphigus vulgaris causes intraepidermal acantholysis with fragile bullae and painful mucosal erosions, risking fluid loss and infection.

Option by option

  • A. It only affects hair follicles

    Hair follicle disease does not define pemphigus.

  • B. Flaccid bullae and mucosal erosions can cause major skin loss (correct)

    Correct: fragile widespread erosions create systemic risk.
