Bromoderma in a patient with migrating partial seizures in infancy.

A 5-month-old boy with migrating partial seizures in infancy acquired bromoderma 4 weeks after initiating potassium bromide (KBr) therapy (60mg/kg/day). Erythematous pustules appeared on the forehead within a few days of attaching electroencephalography electrodes, and on the cheek at the site of nasogastric tube fixation. These later developed into vegetant plaques. Bromoderma aggravated at the site of skin biopsy that was performed 4 weeks after KBr termination. Bromoderma tuberosum should be recognized widely, considering the increasing use of KBr for treating intractable childhood epilepsy.
