A 58-year-old man visited the urological clinic in Prefectural Tohkamachi Hospital with complaint of swelling of bilateral scrotal contents. He had no history of fever, pain or difficulty of urination. Physical examination revealed a giant mass of adult-head size in right scrotum and left inguinal hernia of fist growth. Surgical extirpation of the right scrotal mass and left inguinal herniorrhaphy was performed and the mass was diagnosed as obsolete hydrocele testis and weighed 1,600 g. The excised hydrocele sac showed marked thickening and dark brown pus amounted to about 1,400 ml, which was negative in bacterial culture. Histological examination revealed partial deposits of cholesterol and calcification in tunica vaginalis with extremely atrophic testis and destructive spermatogenesis. The findings suggested the existence of long-term infection in hydrocele testis. The etiology and pathogenesis of this disease is discussed.
