Eczéma de contact au tabac par sensibilisation à l'acide sorbique

The positive test for sorbic acid was relevant not only regarding the lesions on the patient's legs (application of a topical cream containing sorbic acid) but also for the lesion on the patient's thigh and for palmar dyshidrosis (through contact with strands of loose rolling tobacco). To our knowledge, this is the first recorded case of contact dermatitis caused by sorbic acid in tobacco.
