Synopsis
MMP is almost twice as common in females as it is in males, and it is seen most frequently in older individuals.
MMP affects the mucous membranes and, less commonly, the skin. The mouth is involved most often (ie, painful erosions and ulcers), followed by the conjunctiva (corneal inflammation and scarring, conjunctiva inflammation, trichiasis, ectropion, symblepharon, ankyloblepharon, and blindness). Skin, nasal, laryngeal, pharyngeal, and esophageal mucosal surfaces can also be affected, leading to epistaxis, hoarseness, or dysphagia, respectively.
Uncircumcised men may experience phimosis secondary to scarring. Perianal disease may present as perianal erythema and scarring.
Cutaneous disease, when present, most frequently accompanies mucous membrane disease. Occasionally, cutaneous blistering and scarring dominate the clinical picture (so-called Brunsting-Perry variant).
In a 2022 study, malignancies, especially solid organ tumors, were reported in up to 13.8% of patients. These include lung carcinoma, prostate cancer, penile cancer, breast cancer, and non-Hodgkin lymphoma. The malignancy rate was higher when autoantibodies against laminin-332 were found.
