Povidone-Iodine Induced Allergic Contact Dermatitis in a 10-Year-Old Girl: A Case Report.

We present a case of iodine-induced allergic contact dermatitis in a 10-year-old child. The child had a superficial wound on the left knee from an injury and was treated with daily applications of povidone-iodine (PVP-I) ointment for three to four days. The child subsequently developed a worsening skin lesion that increased from an initial 2 cm to 10 cm, spreading over the upper part of the leg, accompanied by pain and scanty discharge. Referred to the dermatology department, the dermatologist diagnosed iodine-induced allergic contact dermatitis based on the clinical presentation and the absence of other oral or topical medications, as well as no history of allergy to any substances or medications. Discontinuation of the suspected PVP-I ointment led to complete healing within 10 days with the use of only an emollient. This case underscores the importance of recognizing iodine allergy as a potential complication when used in wound care, particularly in pediatric patients.
