title: A case of erythema elevatum diutinum associated with B-cell lymphoma: a rare distribution involving palms, soles and nails.
abstract: We report a case of erythema elevatum diutinum (EED) in association with malignant B-cell lymphoma. A 62-year-old man developed EED with an unusual distribution involving the palms, soles and nails. Treatment with dapsone was effective for his skin and nails until he developed generalized lymphadenopathy which turned out to be malignant lymphoma. Many haematological diseases, e.g. IgA paraproteinaemia and myeloma, have been reported in association with EED, but not malignant lymphoma. Even though it may just be a coincidence, we would like to add malignant lymphoma as one of the diseases associated with EED because the activity of EED and malignant lymphoma fluctuated in parallel.
