Cytodiagnosis of Microfilaria at Unusual Sites.

ABSTRACT

Filariasis is a major public health problem especially in tropical countries like India. It is routinely examined in night peripheral blood smears. Fine-needle aspiration cytology (FNAC) is not routinely used for its identification. It has always been detected incidentally, while doing FNACs for evaluation of other lesions. It has been found in lymph nodes, breast, thyroid, cystic lesions, etc. In few reported cases, it has been found even with primary/metastatic malignancy. We also found two cases of microfilaria incidentally. One on USG-guided FNAC of liver SOL (space-occupying lesion) reported as metastatic adenocarcinoma with microfilaria and other in a case of asymptomatic epitrochlear swelling reported as reactive hyperplasia of lymph node with microfilaria.
