Uso da reação em cadeia da polimerase em biópsias de pele para confirmar o diagnóstico histopatológico consistente com leishmaniose tegumentar americana: um estudo de 90 casos

FUNDAMENTOS: Cutaneous leishmaniasis is a chronic, infectious disease caused by protozoa of the genus leishmania. The incidence of this disease is high in Brazil, with 19,746 new cases having been detected in 2008. The presence of amastigotes in the cytoplasm of histiocytes constitutes diagnosis of the disease; however, their presence is rarely found in late lesions, making histological diagnosis difficult. Polymerase chain reaction has been shown to represent a highly sensitive and specific technique for the diagnosis of cutaneous leishmaniasis. OBJECTIVES: To use polymerase chain reaction to...
