title: [Recurrent chancriform mucous membrane ulcer in plasmacytoma with secondary IgA deficiency. Pyoderma chancriforme of the tongue].
abstract: A 66 year old patient presented with a nine month history of recurrent oral ulcerations involving the tongue. We diagnosed chancriform pyoderma and a previously not identified multiple myeloma with secondary immunoglobulin deficiency. Clinically and histologically we excluded a necrotizing ulcerative stomatitis as found in individuals with cellular immunodeficiency as in late-stage HIV-infection. On culture only Neisseria catarrhalis was found. Chancriform pyoderma is often associated with local bacterial infections, especially Staphylococcus aureus. The most common sites are the genitalia and periorbital region; involvement of the oral mucosa is uncommon. To the best of our knowledge, this is the fourth reported case with tongue lesions. The multiple myeloma-associated immunoglobulin deficiency might have facilitated the oral manifestations of chancriform pyoderma.
