Pemphigus Vulgaris as Oral Mucosal Ulcer Progressive to Skin Lesion:

MUCOSAL DISEASES SERIES Number II Pemphigus vulgaris

Pemphigus is a group of potentially life-threatening autoimmune diseases characterized by cutaneous and/or mucosal blistering. Pemphigus vulgaris (PV), the most common variant, is characterized by circulating IgG antibodies directed against desmoglein 3 (Dsg3), with about half the patients also having Dsg1 autoantibodies.There is a fairly strong genetic background to pemphigus with linkage to H...

Mucosal pemphigus vulgaris anti-Dsg3 IgG are pathogenic to the oral mucosa of humanized Dsg3 mice

Mucosal pemphigus vulgaris anti-Dsg3 IgG is pathogenic to the oral mucosa of humanized Dsg3 mice.

There are two major clinical subsets of pemphigus vulgaris (PV)-mucosal PV (mPV) and mucocutaneous PV (mcPV). The mPV subset exhibits anti-human desmoglein (Dsg) 3 autoantibodies that fail to recognize murine Dsg3 (mDsg3); thus, passive transfer experiments of mPV IgG into wild-type (WT) mice have been unsuccessful at inducing disease. We therefore generated a fully humanized Dsg3 (hDSG3) murin...

A rare presentation of oral pemphigus vulgaris as multiple pustules.

Pemphigus vulgaris is an autoimmune blistering disease affecting the mucous membrane and skin. Ulcers, vesicles, bulla, erosions are the common manifestations of the disease. It is uncommon to find multiple pustular lesions in the oral cavity. Here, we report the first case of multiple pustules involving the lateral borders of tongue, buccal mucosa, hard palate, soft palate, vestibule and the g...

Lesions of pemphigus vulgaris on irradiated skin.

Summary Pemphigus vulgaris (PV) is an autoimmune blistering disease produced by IgG autoantibodies against desmoglein (Dsg)3. Lesions on the skin and mucosa can, in rare cases, be induced by radiotherapy. We report a patient with a history of microprolactinoma and PV, who had only oral lesions from the beginning of her illness but 2 months after treatment with radiotherapy for a breast neoplasi...
