Atypical migratory stomatitis and Munchausen syndrome presenting as periorbital ecchymosis and mandibular subluxation

Stomatitis areata migrans, unlike its analogue on the tongue, migratory glossitis, is not easily recognized and is so uncommon and varied in appearance that it may escape definitive diagnosis. It may be so puzzling to the clinician that the patient's credibility may be questioned. A detailed report of a case is presented in which an atypical migratory stomatitis went undiagnosed. Bizarre patient behavior followed in the form of self-inflicted injury (Munchausen syndrome) as the patient attempted to convince the care providers of the true existence of lesions in order to maintain their interest and to obtain relief from discomfort.
