Chronic mucocutaneous candidiasis-thymoma syndrome. A case report.

A 69-year-old woman sought treatment with a history of persistent debilitating intraoral ulcerations and recurrent oral and vaginal candidiasis. The medical history included thymoma, breast cancer, and lip cancer. The oral lesions were consistent with bullous lichen planus. Laboratory studies showed severe hypogammaglobulinemia. The chronic mucocutaneous candidiasis-thymoma syndrome is now recognized as a distinct form of primary immunodeficiency.
