Histopathological Evaluation of Epididymal Filariasis: A Rare Case Report from Southern India

Abstract

Epididymal filariasis is an uncommon manifestation of lymphatic filariasis that presents diagnostic challenges due to its rarity and similarity to other scrotal conditions. We present a detailed case report of epididymal filariasis from Southern India, emphasizing the histopathological findings that were crucial for diagnosis. A 53-year-old male presented with a painful scrotal mass, and subsequent investigations revealed an epididymal mass caused by Wuchereria bancrofti. Histopathological sections from epididymis showed dilated  lymphatic vessel impacted with adult filarial worms having double uterus with surrounding tissue showing fibrosis and dilated congested blood vessels consistent with filarial infection. This case highlights the significance of histopathological workup in diagnosing unusual presentations of filariasis and the need for awareness in endemic regions.
