Lichen planus is not usually associated with malignancy and an association with carcinoid tumour has not been previously described. We now describe a patient in whom lichen planus and a carcinoid tumour presented simultaneously. In this case report, gastrointestinal symptoms of a small intestinal carcinoid tumour coincided with the appearance of a rash which progressed from a generalized exfoliative dermatitis to extensive lichen planus.
