A female patient with painful oral lichen planus that required daily topical corticosteroids completely eliminated cow’s milk/milk products (CMP) from her diet. Her oral discomfort improved about two months later and had mostly resolved by eight months. Blood tests showed an elevation of total immunoglobulin E (IgE) and CMP-specific IgE antibody titers. Over the next seven years, she
was largely asymptomatic when continuing to avoid CMP, with the occasional inadvertent ingestion that resulted in flares.
