Genital tuberculosis occurring in the spermatic cord is a rare disease. A 70-year-old man presented with a mass on the left side of the scrotum which had been painless and had gradually enlarged over the previous 4 months. Surgical excision was performed. The tumorous mass was located in the spermatic cord but did not connect with the testis or epididymis. The removed specimen was 15 x 20 x 15 mm in size and weighed 6 g. Histopathological diagnosis was tuberculosis. At present, 27 months after surgery, recurrence has not been found.
