Rare localized variant of bullous pemphigoid, especially in older people. It comprises a phase of itching followed by varying degrees of blistering. The pretiabile variant affects about 1% of the total BP population (Chang YT et al. 1996). It was described after application of a PD-1 inhibitor in the therapy of metastatic malignant melanoma (Kyle T el al. 2018).

Subepidermal suprabasal bladder.
Direct ImmunofluorescenceThis section has been translated automatically.
C3, IgM and fibrin at the dermo-epidermal border.
Indirect immunofluorescenceThis section has been translated automatically.
Circulating pemphigoid antibodies are not always detectable. In these cases it can be tried to detect antibodies directly from the bladder contents.

TherapyThis section has been translated automatically.
Systemic therapy is usually not necessary. Short-term external therapy with potent glucocorticoids such as 0.05% Clobetasol ointment (e.g. Dermoxin ointment) or 0.1% Diflucortolone ointment (e.g. Nerisona ointment). Cover with ointment grids and sterile gauze dressings. To avoid superinfection, use moist compresses with antiseptic additives such as quinolinol (e.g. quinosol 1:1000 or R042 ) or potassium permanganate (light pink) if necessary.
