ABSTRACT
Local allergic rhinitis (LAR) is a specific phenotype of allergic rhinitis. One characteristic feature of LAR is a medical history indicative of an allergic disease, negative skin-prick test results, undetectable levels of specific IgE, and a positive allergen-specific nasal provocation test. This paper presents a case of a patient with LAR and underlying house dust mite allergy, who was ultimately diagnosed >10 years after the onset of his first symptoms. Currently, there are only pharmacological treatments available for LAR. However, some studies show encouraging results with the use of allergen-specific immunotherapy in LAR, which offer hope for a future use of this causative treatment in LAR patients.
