title: Allergic vulvovaginitis in infancy: study of a case.
abstract: BACKGROUND
  the role of dust mites (Dermatophagoides pt.) in the pathogenesis of allergic vulvovaginitis is still controversial. Association between this mite and atopic dermatitis, conjunctivitis, rhinitis or asthma is already known. Some authors study the possible relationship between some vulvovaginitis and local hypersensitivity. The aim of this study was to corroborate the allergic aetiology due to the mite Dermatophagoides pt. in a girl with vulvovaginitis and perennial rhinitis.
  
  
  RESULTS
  we studied a nine year-old patient with symptoms of perennial rhinitis and unspecific vulvovaginitis of torpid evolution. In vivo and in vitro allergologic tests were performed as well as complete analytic tests including immunoglobulins, urine tests, nasal culture, exudative vaginal culture, and parasitic test. Skin test was positive for Dermatophagoides pt. as well as specific IgE (99.5 kU/L). Total IgE was elevated for her age (492 kU/L). In the rest of the complementary tests, no values out of normality or pathological findings were obtained.
  
  
  CONCLUSIONS
  considering these results, it was suspected that the nasal symptoms and the vulvovaginitis presented by the patient are of allergic aetiology by hypersensitivity to the mite Dermatophagoides pt. The study did not prove relation with bacteria, parasites, Candida albicans or any inhalant allergens other than mites. After three months of treatment with oral antihistamines and topical chromones, as well as environmental avoiding measures, the symptoms totally yielded.
