BACKGROUND Iodine contrast allergy can cause acute and delayed allergic reactions. Just like any other sensitivity reaction, the severity can vary from mild to moderate skin manifestations such as erythematous rash to an even more severe presentation or life-threatening event, such as angioedema and anaphylaxis. CASE REPORT This case report discusses a patient who presented to our institution with a diffuse complex rash 2 days after undergoing CT scan imaging with intravenous iodine contrast injection. The rash started by being maculopapular in nature. Later on, the patient developed a purpuric and petechial pattern, and eventually, an acute exanthematous pustulosis rash was noticed. Several attempts to treat the patient with intravenous corticosteroids failed. Three days after admission (5 days after the rash started), topical steroids were used in place of parenteral steroids. The rash showed remarkable improvement in a very short time. The patient was diagnosed with delayed hypersensitivity IV iodine reaction, resistant to parenteral corticosteroids. The workup of such an extensive rash and odd presentation include several laboratory tests and skin testing to be able to rule out more serious differential diagnoses. CONCLUSIONS This case is unique as it enables us to show the importance of substituting topical management, more specifically, topical steroids that might even replace parenteral steroids, to our management in order to treat allergic reactions, especially in the presence of a rash. |
