Irritant contact dermatitis with tincture of iodine.

Abstract

A 5-year-old girl was first visited due to an eczematous dermatitis of both side surfaces of the right knee (Fig. 2, 3), arisen after several medications with tincture of iodine following intervention of positioning metal cramps on the right distal femoral metaphysis. The operation was performed 2 weeks earlier to resolve a dysmetria of the lower limbs, present from the early months of life and diagnosed as Beckwith-Wiedemann syndrome. Physical examination showed (Fig. 3) a round erythematous, vesicular and erosive patch around the surgical scars of the right knee. The lesions, which were absent in site of plaster, regressed quickly suspending the use of iodine tincture and applying a corticosteroid lotion. The skin patch tests performed with tincture of iodine supplied by the parents were negative leading to the final diagnosis of irritant contact dermatitis with iodine.
