letter to editor: toxocara canis and chronic urticaria

Editor, the recent article on “toxocara canis igg seropositivity in patients with chronic urticaria (cu)” is very interesting. burak-selek et al. reported that “t. canis may trigger cu since we found 17.8% seropositivity in 73 patients with cu and none in 109 healthy individuals.” in fact, t. canis is an uncommon parasitic infestation. in tropical countries, the patients can present with dermatological problems due to this parasite. in a recent case series report, skin problem can be seen in 43 % of the patients. in animal model, the induction of eosinophilia due to this parasite can be observed.
