Diagnosis of visceral leishmaniasis by fine needle aspiration cytology of an isolated cervical lymph node: case report.

A 61-year-old woman presented with an isolated, painless, slightly enlarged right laterocervical lymph node without any other signs and symptoms of disease. Laboratory test including hematological and biochemical parameters were normal. A cervical ultrasonography demonstrated one lymph node (10 mm) on the right laterocervical side and one small reactive lymph node on the left laterocervical side. The fine needle aspiration (FNA) smears revealed a polymorphic population of cells composed of lymphocytes, histiocytes, epitheloid cells, plasma cell, tingible body macrophages and macrophages infiltrated with Leishmania amastigotes. Treatment was initiated with Stiboglukonat Na (Pentostam) and led to a full recovery.
