Presently described is the case of an 11-month-old-girl diagnosed with acute urticaria due to parainfluenza virus type 3 (PIV-3). This rare etiological agent of urticaria was isolated from a nasopharyngeal swab after the development of bronchiolitis. The patient had received treatment at another clinic for a maculopapular skin eruption, rhinorrhea, fever, and a cough; however, after a lack of response and a progression of symptoms, she was brought to our pediatric allergy and immunology polyclinic. A physical examination revealed diffuse and resistant urticarial plaques on the body and she was admitted for further evaluation and therapy. Bronchiolitis developed and auscultation on the second day of admission revealed bilateral subcrepitant rales and wheezing. Treatment with salbutamol 6x0.15 mg/kg/dose was initiated, and pheniramine 1.4 mg/kg/day (in 2 doses) and ranitidine 2 mg/kg/day (in 2 doses) were added for the urticaria. PIV-3 was isolated from a nasopharyngeal swab. It is important to remember that viral infections can have a significant role in the etiology of acute urticaria in childhood. A detailed medical history and laboratory evaluations for infection may be needed for a thorough differential diagnosis and evaluation of etiological factors in urticarial disease.
