The mean age was 52.2 (SD 20.2) years with near-equal sex distribution. Oral mucosa was the commonest initial site (44.7%, 73\/163); flexural areas such as the\u00a0groin and axilla were frequently involved. Reported triggers included drugs, infections and vaccination. In 89 patients where clinical subtypes were reported, the Hallopeau variant was found in 47 (53%). When treatment outcomes were reported by subtype, patients with the Hallopeau variant demonstrated higher sustained remission rates (68%, 28\/41) and lower mortality (2%, 1\/41) compared with those with the Neumann variant [52% (16\/31) sustained remission; 16% (5\/31) mortality]. Key histological findings included suprabasal acantholysis (84.9%, 158\/186) and eosinophilic microabscesses (65.1%, 121\/186). Direct immunofluorescence showed intercellular IgG (92.4%, 121\/131) and C3 (53.4%, 70\/131). Oral corticosteroids (89.5%, 145\/162) were the most used therapy.
