Cryptorchid testis have a greater risk of malignant change than do normally descended testis. The undescended testis would also be susceptible to torsion by the mechanism of increase in testicular size. A 36-year-old man of torsion of malignant undescended testis is presented. He was diagnosed as having incarcerated inguinal hernia on his first visit to general surgeon due to acute left lower abdominal pain. At laparotomy, a 7.5 x 5.5 x 3.0 cm3, greyish tan color mass was found. The pathological diagnosis is choricarcinoma and teratoma, mixed germ cell tumor. We would emphasise that in any patient presenting with acute abdominal symptoms and an absent scrotal testis, the possibility of a complication of torsion of undescended testis should be considered.
隐睾发生恶变的风险比正常下降的睾丸更高。未降入阴囊的睾丸也容易因睾丸体积增大而发生扭转。本文报道了一名36岁患有恶性隐睾扭转的男性患者。他因急性左下腹疼痛首次就诊于普通外科医生时被诊断为嵌顿性腹股沟疝。剖腹手术时，发现一个7.5×5.5×3.0立方厘米、灰棕色的肿块。病理诊断为绒毛膜癌和畸胎瘤，混合型生殖细胞肿瘤。我们要强调的是，对于任何出现急性腹部症状且阴囊内睾丸缺如的患者，都应考虑到未降入阴囊睾丸扭转并发症的可能性。
