Abstract:
We present two cases of cutaneous erythroderma induced by carbamazepine therapy, both cases with just cutaneous affection and only one suspicious drug. A cutaneous patch study, with standard battery from the Spanish Contact Dermatitis Research Group, vaseline with carbamazepine at 10% and lectures at 48 and 96 hours, was conducted. The result was positive for carbamazepine and negative for all other patches in both cases. All controls were negative. This is a very simple test, easy to perform, specific and with low side effects, allowing the diagnosis of this pathology.
