Microfilariae of Wuchereria bancrofti in a lymph node aspirate. A case report.

Microfilariae of Wuchereria bancrofti were detected by fine needle aspiration biopsy (FNAB) in an axillary lymph node from a 27-year-old female. The patient also had intestinal tuberculosis. A routine hemogram did not show any eosinophilia, and three consecutive night blood samples also were negative for microfilariae. This was an early case of filariasis without microfilaremia and was detected by FNAB of the lymph node. The association of filariasis and tuberculosis was purely coincidental.
