Incidental Detection of Microfilaria on Fine-Needle Aspiration Cytology (FNAC) of a Breast Lump-A Case Report

Abstract

Introduction: Filariasis is a major public health problem in tropical countries like India. It is caused by Wuchereria bancrofti and Brugia species. The diagnosis is conventionally made by demonstrating microfilariae (MF) in the peripheral blood smear. Microfilariae (MF) have been incidentally detected in fine needle aspiration cytology (FNAC) smears of various lesions in clinically unsuspected cases of filariasis with absence of microfilariae in the peripheral blood. Case presentation: We report a case of MF in the breast diagnosed on fine needle aspiration cytology (FNAC) smears of a 32 years old woman. It was clinically diagnosed as fibroadenoma breast. Conclusion: The identification of MF in FNAC smears plays a significant role in diagnosis of disease and institution of specific treatment.
