title: Ramipril-associated lichen planus pemphigoides.
abstract: We report the first case of lichen planus pemphigoides (LPP) secondary to ingestion of ramipril, an angiotensin-converting enzyme inhibitor. Clinical, histological and immunofluorescent findings were all consistent with a diagnosis of LPP. Linear basement membrane zone (BMZ) staining with IgG and C3 was only seen at the roof of split-skin preparations and circulating autoantibody to the BMZ was present at a titre of 1/100. Controlled immunoblotting of epidermal extracts detected the bullous pemphigoid antigens of 230 and 180 kDa.
