Immunoblotting (IB) using recombinant laminin-421 revealed a weak IgG positivity and confirmed the absence of antibodies against BP180, BP230, and LAD antigens. Indirect immunofluorescence (IIF) on SSS showed linear IgG deposition at the dermal side of BMZ. Anti-p200 pemphigoid is a rare subset of the pemphigoid group, in which the target antigen corresponds to laminin- 1, a 200 kDa protein located within the lower lamina lucida of the basement membrane zone (BMZ).1 An 89-year-old Caucasian man presented with a 2-month history of a widespread cutaneous eruption associated with a modest itch.
