This increase may be related to the epidemiologic expansion of the infective agent and the increase in tourism in tropical areas. The difficulty in clinical diagnosis, mainly in areas in which CL is not the first consideration of local physicians, has intensified efforts to describe diagnostic tests, which should be specific, sensitive, and practical. Amongst the new tests described are those including nucleic acid amplification (polymerase chain reaction, PCR) and immunohistochemistry (IHC).<\/jats:p><jats:p><jats:bold>Methods\u2002<\/jats:bold> In this study, we evaluated the sensitivity of a PCR based on small subunit (SSU) ribosomal DNA, in comparison with IHC using <jats:italic>Leishmania <\/jats:italic>spp. antibodies, in biopsies embedded in paraffin.<\/jats:p><jats:p><jats:bold>Result\u2002<\/jats:bold> The results indicated a total sensitivity of 96% (90.9% with PCR and 68.8% with IHC), showing the possibility of using paraffin\u2010embedded biopsies to diagnose CL.<\/jats:p><jats:p><jats:bold>Conclusion\u2002<\/jats:bold> We propose the use of the two tests together as a routine protocol for diagnosis.
