Background: Paratesticular tumors are uncommon lesions arising from structures adjacent to the testis, including the epididymis, spermatic cord, and tunica vaginalis. Although most extratesticular masses are benign, they may clinically mimic testicular malignancy, leading to diagnostic uncertainty. Case Presentation: A 53-year-old man, an active smoker with a 30 pack-year history, presented with a progressively enlarging right scrotal mass evolving for more than 6 months. Scrotal ultrasonography showed a well-defined solid mass adjacent to the right testis measuring approximately 8 cm in diameter. Tumor markers were alpha-fetoprotein 12.56 IU/mL, beta-human chorionic gonadotropin <1.2 IU/mL, and lactate dehydrogenase 180 IU/L. Surgical exploration through an inguinal approach identified a large paratesticular mass originating from the tunica vaginalis. The lesion measured 9.5 x 8.5 x 6 cm, was completely excised while preserving the testis, and histopathology confirmed an inflammatory fibrous pseudotumor with negative surgical margins. No recurrence was observed after 6 months of follow-up. Conclusion: Paratesticular fibrous pseudotumor is a rare benign lesion that may mimic testicular malignancy. Complete excision with histopathological examination is essential for definitive diagnosis and may help avoid unnecessary orchiectomy.
