Realizou-se estudo comparando o uso da reação em cadeia da polimerase à evolução clínica e painel de exames tradicionais para diagnóstico em pacientes com suspeita clínica de tuberculose cutânea e micobacteriose atípica. Observou-se sensibilidade da reação em cadeia da polimerase de 88%, especificidade de 83%, valor preditivo positivo de 82%, valor preditivo negativo de 88% e acurácia de 85% com concordância pelo teste de McNemar (p= 0,655). Os exames do painel de maior acurácia, após a reação em cadeia da polimerase, foram o teste tuberculínico com acurácia de 79% e a presença de dermatite crônica granulomatosa com reação em cadeia da polimerase positiva com acurácia também de 79%, ambos com concordância pelo teste de McNemar (p= 0,179 e p= 0,655, respectivamente) / A study was performed comparing the polymerase chain reaction and the traditional panel of exams for the diagnosis in patients with a clinical suspicion of cutaneous tuberculosis and atypical mycobacteria infection to the clinical evaluation. It was observed that the sensitivity of the PCR was 88%, the specificity was 83%, the positive predictive value was 82%, the negative predictive value was 88% and the accuracy was 85% in agreement with the McNemar test (p=0.655). The panel exams of second highest accuracy, were the tuberculin test with an accuracy of 79% and the chronic granulomatous dermatitis with positive PCR, also with an accuracy of 79%, both in agreement with the McNemar test (p=0.179 and p=0.655, respectively)
