An acneiform eruption secondary to iododerma

Iododerma is a rare eruption caused by the inadvertent accumulation of iodine. Published sources of iodine excess producing iododerma include oral and intravenous iodinated contrast dyes, potassium iodide, amiodarone, and topical wound care products such as povidone iodine and iodoform gauze or in expectorants.1-7 Iododerma is more common in patients with renal dysfunction because of the impaired renal clearance and accumulation of iodine.8 One study of patients with end-stage renal disease who received iodinated contrast documented that the plasma half-life of the contrast was increased to 23 hours compared with 2 hours in those with normal kidney function.
