--- The aim of this research was to investigate the relationship between the clinical diagnosis of tuberculosis, the results of tuberculosis polymerase chain reaction (TB-PCR) and fluorochrome auramine “O” staining in histological embedded tissues of pleural biopsy. Were used 48 formalin-fixed paraffinembedded tissue obtained from the archives of the Department of Pathology from Hospital San José del Callao and Instituto Nacional de Enfermedades Neoplásicas. 30 cases were clinically diagnosed with tuberculosis and 18 having another diagnosis different from tuberculosis. 29 of 30 cases having tuberculosis were TB-PCR positive. All of 18 negative cases were TB-PCR negative. The sensibility and the negative predictive value of TB-PCR were 96,7% and 94,7% respectively. On the other hand the sensibility and the negative predictive value of AFB-Auramine were 58,6% and 56,7%. The positive predictive value was 100% in both cases. TB-PCR is a very sensitive method for TB diagnosis in formalin-fixed, paraffin embedded pleural biopsies.
