Breast filariasis masquerading as carcinoma

Abstract

Filariasis is a common public health problem in the Indian subcontinent. Microfilariae are usually detected in the peripheral circulation; however, the clinical manifestations are related to the lymphatic system primarily. The breast is an uncommon site for filariasis, and the lesion clinically mimics malignancy. We should consider filariasis in the differential diagnoses of breast lumps, especially in endemic areas. Fine-needle aspiration cytology from the breast lump allows easy detection of filarial infection, and this can be managed by medical treatment, thereby avoiding surgical procedures.
