Abstract: Objective: To compare the sensitivity of Real-time fluorescence quantitative PCR (qPCR) in detecting Mycobacterium tuberculosis (MTB) in cutaneous tuberculosis (CTB) both in paraffin-embedded tissues and fresh tissues,to discuss the feasibility of qPCR detection in paraffin tissues of CTB. Methods: MTB in 6 fresh tissues and 20 paraffin-embedded tissues of CTB were detected by qPCR. Results: The sensitivity rate of fresh tissues and paraffin-embedded tissues were 50% and 35% respectively. Conclusion: QPCR can be applied both in the fresh CTB tissues and paraffin-embedded tissues. The sensitivity of the former is higher than the latter.
