Recurrent aphthous stomatitis.
Aphthous ulcers are of unknown etiology; both genetic and immunologic origins have been proposed. Lesions are painful, tend to recur and may last up to six weeks. Recurrent aphthous stomatitis must be differentiated from herpesvirus infections and herpangina. No treatment has been uniformly successful, but levamisole shows promise.
