Leishmaniasis as a Neglected Cause of Isolated Lymphadenopathy: A Case Report

Leishmaniasis is an endemic parasitic disease in Iran. This paper reports the case of a 5-yr-old boy who presented with multiple isolated cervical lymphadenopathy for several months with no history of fever and no signs or symptoms. In an excisional lymph node biopsy, Leishmania parasites were histologically detected. Thus, leishmaniasis should be included in the differential diagnosis of isolated lymphadenitis in immunocompetent patients, even if the K39 and IFA for kala-azar are reported as negative.
