Presentation Transcript
Mucous membrane pemphigoid (MMP) is chronic blistering or vesiculobullous disease that affects predominately oral and ocular mucous membranes. an autoimmune disease (autoimmune reaction to basement membrane protein ) with an unknown stimulus. Deposition of Ig and complement component along the basement membrane zone ( on DIF testing ) are characteristic.
Histopathology: MMP is a subepithelialcleftingdisorder and there is no acantholysis. In early stages few lymphocytes are seen, but with time the infiltrate becomes more dense and mixed.
Direct immunofluorescence studies a continuous linear band of immunoreactantsat the basement membrane zone in nearly 90% of affected patients IgG and C3, although IgA and IgM Indirect immunofluorescence is positive in only 5% of these patients
