Vasculitis por reacción de hipersensibilidad tipo III

[摘要] The immune processes are used by the body to defend against the aggression of infectious agents; however, in certain cases, the body reacts inappropriately or excessively causing various types of tissue damage. These situations, which we know as hypersensitivity, can have positive or negative aspects by being able to cause the disease themselves. We present the case of a 14-year-old girl who attended the "William Soler" Pediatric Teaching Hospital after several admissions to other health centers, where the diagnosis of a mature foot was raised. After several investigations and with the history of allergy to different drugs, the recurrent tonsillitis symptoms, the laboratory data and the clinic presented by the patient, the diagnosis of a vasculitis due to type III hypersensitivity reaction was established. Because of the atypical characteristics of this patient's clinical picture and the difficulty in reaching a diagnosis, the presentation of this case is important.
