A Rare Case of Isolated Testicular Filariasis Mimicking Intra-Testicular Neoplasm

Isolated testicular filariasis is extremely rare, with only a handful of cases reported in medical literature. The exact mechanism of testicular involvement remains unclear, although hypotheses suggest hematogenous spread or direct extension from nearby lymphatic structures. Clinical presentation often mimics testicular tumors, manifesting as painless testicular enlargement or palpable masses. Imaging modalities such as ultrasound may initially suggest malignancy, necessitating histopathological examination for definitive diagnosis. Management typically involves surgical excision of affected testicular tissue, aiming to relieve symptoms and prevent complications. In endemic regions, a high index of suspicion for filariasis should be maintained, especially when encountering unusual presentations of testicular pathology. Awareness among clinicians and pathologists is crucial for timely diagnosis and appropriate management of this rare manifestation of filariasis.
