[Tuberculosis in the autopsy. Clinical and pathological study: an analysis of 92 cases of active tuberculosis found in 2,180 autopsies].
OBJECTIVE
Tuberculosis is an infectious disease currently having great importance in the daily clinical practice in Spain. Some cases of active tuberculosis are not identified until after the patient had died and an autopsy has been performed. This study has analyzed the clinical and pathological characteristics of patients diagnosed with active tuberculosis in the autopsy.


METHODS
We reviewed all the autopsies performed in the University Hospital 12 de Octubre of Madrid between 1974 and 2002. The autopsy reports and clinical records were examined in those cases in which active tuberculosis was found.


RESULTS
We found 92 cases of active tuberculosis, 57% corresponding to men. Mean age of this group was 64 years. A total of 20% of the patients died within 48 hours after admission. Predisposing factors were identified in 90% of the cases. Dyspnea (24% of cases) and wasting syndrome (23%) were the main symptoms that motivated patients to request medical attention. Up to 30% of cases had normal chest X-ray. Tuberculosis was suspected in only 46% of patients before death. Principal cause of death was tuberculosis in 61% of patients, 52% of patients had pulmonary tuberculosis, 28% suffered from miliary tuberculosis and 20% from extra-pulmonary tuberculosis. The lungs were the most frequently affected organ. Epithelioid granulomas were found in all patients.


CONCLUSIONS
Tuberculosis is an uncommon finding in the autopsy as the cause of death. The presence of unspecific symptomatology, insufficient cost-effectiveness of the diagnostic tests and precocious death, are identified as the most frequent causes of undiagnosed tuberculosis.
