title: [Systemic reaction after performing a food prick-to-prick test. A case report].
abstract: Skin prick test is the most widely used test for the diagnosis of IgE-mediated conditions. Commercial extracts are used for its performance, but in the case of fruits and vegetables it is preferable using fresh food. Although both tests possess a good safety profile, hypersensitivity reactions have been recorded.
  
  
  
  Forty-seven-year old woman with a history of persistent allergic rhinitis, sensitized to the pollen of grasses, olive and salsola; she was referred to an allergology department due to anaphylaxis triggered by the consumption of avocado, cantaloupe, carrots and watermelon. Minutes after skin prick test with standardized extract and skin prick with fresh foods, she developed dyspnea, pruritus, erythema, dizziness and sibilance; she was administered 0.5 mg of intramuscular adrenalin and 4 salbutamol inhalations and placed in the Trendelemburg position. Dyspnea persisted, and vital signs monitoring showed heart and respiratory rates increase and, hence, salbutamol was applied again, together with 2 L/min of oxygen delivered by nasal cannula, intravenous fluids and 100 mg intravenous hydrocortisone; improvement was observed at 40 minutes. The patient was hospitalized for 48 hours.
  
  
  
  Although skin tests are safe, the risk of hypersensitivity and anaphylactic reactions should not be ruled out, especially in susceptible patients.
