Coexistence of microfilaria with metastatic adenocarcinomatous deposit from breast in axillary lymph node cytology: A rare association

Abstract

Filariasis is a global social health problem of tropical and sub tropical countries like India. W.bancrofti accounts for 95% of cases of lymphatic filariasis. Microfilaria in cytosmears are a rare finding. We report a case of 55 year old female presented with right axillary swelling with ipsilateral breast lump. Cytosmears from the lymph node aspirate showed metastatic adenocarcinomatous deposits and a bunch of microfilariae surrounding the tumor cells and the aspirate from the breast shows ductal carcinoma. We report an additional case of a rare association of microfilaria co-existing with carcinomatous deposit in the lymph node.
