Correct answer: B — Allergic contact dermatitis to epoxy resin

Positive patch testing to epoxy resin with exposure-linked flares confirms allergic contact dermatitis. Vesicular itchy eczema on exposed skin is typical. Irritant dermatitis remains common but would not explain the positive relevant allergen test. Once sensitised, very low exposure may provoke recurrence.
