Nodular breast lesion caused by Bancroft's filariasis

ABSTRACT

A case of subcutaneous breast nodule caused by the filarial worm Wuchereia bancrofti is described. The patient, who had lived continuously in Montreal for the previous five years, was a native of British Guiana. The nodule, a granulomatous lesion, first noted by the patient two weeks before its removal, presumably developed following the death of an adult filarial worm in a breast lympathatic channel. The infection was characterized by the presence of typical microfilariae in night blood, and by eosinophilia (AU)
