绝大多数睾丸肿瘤均起源于生殖细胞。非生殖细胞起源的肿瘤仅占全部睾丸肿瘤的1—3％。而非生殖细胞起源的肿瘤中,起源于支持细胞(Sertoli Cell)的则更为少见。现报告一例如下: 戴某,男性,65岁。五年前发现左侧睾丸有一小硬块,无任何不适。近半年来因包块迅速增大而就诊。检查:左侧阴囊明显增大,其下部可触及一7cm×5cm×5cm大小的囊性包块,透光试验阳性。其上部可触 The vast majority of testicular tumors originate in germ cells. Tumors of non-germline origin account for only 1-3% of all testicular tumors. Of the tumors that are not germ cell origins, those that originate in the Sertoli Cell are less common. The following is an example: Dai Mou, male, 65 years old. Five years ago found a small lump on the left testis, without any discomfort. In the past six months due to mass rapid increase in treatment.
