症例:45歳男.右陰嚢内の腫瘤に気付き受診.悪性腫瘍の可能性は低いと考え経過観察とした.経過中腫瘤増大傾向を認めたため,良・悪性の鑑別も兼ねて手術目的で入院した.精巣の組織を一部つけて腫瘤摘出術を行い,精巣は温存した.術後経過は良好で,6ヵ月を経過した現在再発などは認めない.病理組織所見では精巣白膜に発生したAdenomatoid tumorと診断し,良性腫瘍であるので追加治療は行っていないA case of male adenomatoid tumor of tunica albuginea of the testis is reported. A 45-year-old man referred to our hospital because of intrascrotal mass on the right side. The mass increased in size for eight months. Then we excised the tumor, and spared the right testis. The tumor was arising from the tunica albuginea of the testis with a pedicle. The histological diagnosis was adenomatoid tumor. Adenomatoid tumor is a rare benign tumor. A total of 97 cases of adenomatoid tumor of epididymis have been reported in males, but only 23 cases of adenomatoid tumor of the testis have been reported in Japan. Herein, 24 cases of adenomatoid tumor of testis including our case are discussed and reviewed.
