Iododerma Occurring After Orally Administered Iopanoic Acid

• A 45-year-old man with multiple myeloma developed iododerma after oral cholecystography with iopanoic acid. The lesions appeared two days after two exposures to iopanoic acid given within one week. To our knowledge, this is the first reported case of iododerma in association with multiple myeloma and orally ingested radiocontrast dye. ( Arch Dermatol 1987;123:387-388)
