Follicular Traction Urticaria: A New Form of Chronic Inducible Urticaria?
Résumé
In the new classification of chronic urticaria, two distinct subtypes have been proposed including spontaneous urticaria and inducible (or physical) urticaria. By definition, chronic inducible urticaria (CIndU) is elicited by a specific trigger, such as sunlight, water, sustained local pressure, vibration, hot or cold environments. Follicular traction urticaria (FTU) is characterized by the development of follicular urticarial papules exclusively after being triggered by hair traction or removal. We suggest that FTU could be a new form of CindU but further studies are needed.
