title: [Systemic necrotizing vasculitis in autopsy].
abstract: OBJECTIVE
  To analyze the characteristics of systemic necrotizing vasculitis observed in necropsy emphasizing the non-diagnosed cases until necropsy and to identify the reasons of clinical confusion.
  
  
  METHODS
  Necropsies of adult patients performed in Hospital General La Paz, Madrid, from 1966 to 1977 were reviewed. Clinical manifestations, analytical changes and involvement of different organs were analyzed. The correspondence degree between clinical and necropsic diagnoses was studied.
  
  
  RESULTS
  A total of 18 cases of necrotizing vasculitis were observed out of 3,980 necropsies. The most common clinical manifestations were fever and general syndrome (60%). The organs most commonly involved were kidney (94%) and gastrointestinal tract (56%). Diagnosis was revealed by necropsy in 39% of cases; in these cases, the incidence of heart failure and peripheral neuropathy was significantly lower, whereas digestive hemorrhage and liver, pancreas, adrenal gland, and bladder involvement was significantly higher.
  
  
  CONCLUSIONS
  Systemic necrotizing vasculitis in underdiagnosed, which can be partly explained by the lack of specificity of the most common symptoms and the paucity of characteristic clinical and organ-specific manifestations which leads to confusion with more prevalent conditions.
