Potassium bromide is still in use for the treatment of multidrug-resistant seizures. It is a known cause of severe drug-induced skin disorders. The clinical presentation of bromoderma may be similar to that of pyoderma gangrenosum when occurring with a single lesion. The case of a young girl with a single vegetating plaque of bromoderma on the leg is reported. The presence of pustules at the periphery of the plaque provides the clinical clue to the diagnosis.
