We report two cases of μ—heavy-chain disease. Both patients were affected with a lymphoproliferative disease that shared several suggestive features with the previously reported cases of μ-chain disease: the presence of vacuolated plasma cells in bone marrow, a small amount of α2 moving abnormal μ-chain protein, and urinary K Bence Jones protein in one case.
