Abstract:
The impact of indoor allergens is greater than that of outdoor or occupational environments. Cockroaches have been demonstrated to be an etiologic factor in allergic diseases, especially in patients with lower socioeconomic classes in large urban areas. Infestations of cockroaches are largely dependent on housing conditions, and hypersensitivity is dependent on exposure. We herein report a 38-year-old man with factitious urticaria revealed strong positive reactions to crude extracts of American cockroach and German cockroach at a skin pinprick test and Western blot analysis.
