Leishmaniasis in a patient with HIV co-infection: Diagnosis on fine needle aspiration cytology.

Leishmaniasis is a vector borne parasitic disease caused by obligate intracellular protozoa Leishmania and is transmitted by the bite of sand fly. The disease typically presents in visceral, cutaneous and mucocutaneous forms and is endemic in some states of India. Cases with atypical presentation are seen when patient has co- infection with HIV. We report a case of Leishmaniasis occurring in a HIV seropositive expectant mother diagnosed initially on fine needle aspiration cytology. The patient was resident of non endemic area and had presented with isolated cervical lymphadenopathy and fever without spleenomegaly. Characteristic morphological features of Leishmania seen in the fine needle aspiration smears from the neck nodes were identified and definitive diagnosis of Leishmaniasis could be given. Cytological features were not suggestive of any other disease. Timely diagnosis of the disease facilitated proper management in our patient.
