Isolated Trochlear Lymphadenopathy: A Rare Presentation of Filarial Worm Infestation

INTRODUCTION: Isolated epitrochlear lymphadenopathy is a rare presentation of filariasis. Filariasis is endemic in tropical and sub-tropical countries. It usually affects the lower limb presenting as elephantiasis, epididymitis, orchitis. CASE REPORT: A 9yr old mle child presented with an isolated epitrochlear lymphadenopathy, with no other specific signs and symptoms. We report a case with fine needle aspiration cytology findings of filarial worm infestation at an unusual site in clinically unsuspected case. CONCLUSION: A high degree of suspicion is recommended for such infections at uncommon sites in endemic countries, like India, for early detection and prompt treatment.
