Mucous Membrane Pemphigoid
Diagnosis of Mucous Membrane Pemphigoid
Skin biopsy and direct immunofluorescence Prevalent mucosal involvement and scarring lesions help distinguish MMP from bullous pemphigoid. Diagnosis of mucous membrane pemphigoid is supported by lesion biopsy and direct immunofluorescence. Linear basement membrane deposits may include IgG, IgA, and C3. Serum autoantibodies tend to be absent or at low titre.
