Breast Filariasis—Diagnosed by Fine Needle Aspiration Cytology: A Rare Case Report

Filariasis and its consequences are a major health problem in tropical countries, including the Indian subcontinent. Lymphatic filariasis affects 90 million people worldwide. Despite the huge number of people affected all around the world, it is quite infrequent to find microfilaria in routine cytological smears and body fluids. The breast is an uncommon site for the occurrence of a filarial nodule, and only a few cases have been documented. We report a case of a young female who presented with a painful right breast lump. Clinically suspected of neoplasm, and ultrasound was suspicious for filariasis. FNAC (fine needle aspiration cytology) was used to make the final diagnosis of filariasis.
