title: [Diagnosis of the testicular tumor (57 case reports)].
abstract: OBJECTIVE
  To improve the diagnosis of the testicular tumor.
  
  
  METHODS
  Fifty-seven cases, including their signs and symptoms, imaging studies, tumor markers and histologic diagnoses, were reviewed.
  
  
  RESULTS
  31.3% of the patients failed to go to hospital in time. B mode ultrasound and CDFI had sensitivity of 93.5% and 96.4% respectively. Compared with final diagnoses, 23 from 26 cases (88.5%) were correspondingly diagnosed by intraoperative frozen section examination (FSE), which, however, had no definitive influence on the surgical management. Histologic examination showed 22 patients with seminoma, 9 with embryonal carcinoma, 7 with teratoma, 3 with yolk sac tumor, 9 with combined patterns, 4 with lymphoma, and 3 with other histologic types of tumor.
  
  
  CONCLUSIONS
  For earlier diagnosis, patients testicular self-examination counts for much, and ultrasound and CT should be used before possible histologic examination, while all patients with testicular tumors should have intraoperative FSE, which is very practical in identifying malignant and benign masses, and in choosing between enucleation of the tumor and radical orchiectomy.
