[Halogen-induced panniculitis caused by potassium bromide].

Necrotizing panniculitis due to potassium-bromide is a drug induced allergic reaction following stimulation of lymphocytes as demonstrated for the first time by a lymphocyte transformation test (LTT). We named the disease "halogen panniculitis" because of similar generally known reactions to iodides and describe the typical symptoms in three own cases. Bromoderma tuberosum tends to be a similar kind of allergy. For the first time pancreatitis to potassium bromide in men has been observed, which has already been described in epileptic dogs treated with potassium bromide.
