Leishmania lymphadenitis diagnosed by fine-needle aspiration biopsy

A case of Leishmania lymphadenitis which presented clinically as an isolated left laterocervical lymph node is described. Diagnosis was made by fine-needle aspiration biopsy (FNAB), as in other cases previously reported. The material obtained yielded abundant histiocytes, multinucleated giant cells, and epithelioid microgranulomas with Leishman-Donovan pathognomic bodies in the cytoplasm of cells, together with free forms of the parasite. This paper comments on the main differential diagnoses to be considered in our region when faced with granulomatous adenitis and the role of FNAB in the identification of this parasite in endemic areas.
