Mucous Membrane Pemphigoid (MMP) is a rare and chronic autoimmune blistering disorder that primarily affects the mucous membranes, including those of the mouth, eyes, nose, throat, and genital areas. This condition arises when the immune system mistakenly targets proteins found within the basement membrane of these tissues, leading to the formation of painful blisters, erosions, inflammation, and potential scarring. If MMP is left untreated, it can lead to serious complications, particularly in ocular cases, where progressive scarring may impair vision or result in blindness. Therefore, early diagnosis and appropriate therapeutic intervention are crucial.
