A Case of Tuberculosis Verrucosa Cutis Diagnosed by Using Polymerase Chain Reaction

For a definitive diagnosis of cutaneous tuberculosis, the demonstration of the mycobacteria is essential, but routinely available methods such as AFB stain and culture have poor sensitivity and are time-consuming. Recently, PCR has emerged as a promising tool in the diagnosis of cutaneous tuberculosis due to its high sensitivity and speed. We herein report a case of tuberculosis verrucosa cutis without demonstarable acid-fast bacilli, but diagnosed by using PCR.
