Modification to the approach of the diagnosis of mucous membrane pemphigoid: A case report and literature review.

Mucous membrane pemphigoid (MMP) is a subepithelial blistering disease predominantly involving the mucosal surfaces. Distinct subgroups of MMP have recently been identified by using advanced immunopathologic and immunochemical techniques and are described in the literature on the basis of their clinical features and antigenic specificities. Antiepiligrin MMP has been described as an immunochemically distinct entity. Evidence of an existing relationship between malignancy and antiepiligrin MMP has been well documented in the medical literature. This case report illustrates a case of antiepiligrin MMP in a patient with an advanced cancer of the bladder.
