DIF usually shows immunoglobulin G (IgG) deposited on the surface of the keratinocytes in and around lesions. IgG1 and IgG4 are the most common subclasses. Complement components such as C3 and immunoglobulin M are present less frequently than IgG.
How do you biopsy a bullous pemphigoid?
Bullous Diseases: Mucosal Biopsy Sites Top If erosive lichen planus (LP) is suspected, take mucosal biopsy with ~2/3 normal mucosa and ~1/3 edge of a lesion, for best results. If in doubt, take two DIF biopsies, one with edge of a lesion, as for LP, and one normal, as for pemphigoid for best results.
What is the difference between pemphigus and pemphigoid?
How to get rid of bullous pemphigoid?
