Follicular traction urticaria

Abstract

Inducible urticaria is a heterogeneous subgroup of chronic urticarias caused by a wide variety of environmental stimuli, such as exercise, cold, heat, pressure, sunlight, vibration, and water. A new term, follicular traction urticaria, was suggested as an unusual form of inducible urticarias. We report a patient who was diagnosed with follicular traction urticaria.

Follicular traction urticaria: Is there a delayed onset form?

“…All cases consist of young women developing hives after a short period of time as a result of a traction stimulus. [1][2][3][4][5][6][7] Diagnosis is based on this clinical presentation and the exclusion of other subtypes of chronic inducible urticaria. Differential diagnosis should be performed with follicular dermographism.…”

Follicular traction urticaria: Reporting a rare case

“…[4] Duman et al in 2016 suggested that hair traction (rather than skin traction) specifically releases a different kind of antigen that interacts with IgE sensitized mast cells around the hair follicle, which could be responsible for the above Indian Journal of Skin Allergy phenomenon. [5] So far, FTU has only been reported in young females with the absence of any history of urticaria or dermographism. Notably, among the seven other such reported cases in English literature, six cases had wheals lasting for less than 3 h. Our case is more similar to the one reported by Raison-Peyron [6] in whom the wheals lasted 15-18 h. The longer duration is probably due to the force of traction applied and more studies are required to further explore this.…”
