ABSTRACT
PATIENTS AND METHODS: We underwent a retrospective study of five cases of testicular cancer in undescended testis. The parameters of study were: age at diagnosis, circumstances of diagnosis, values of tumour markers, and pathological aspects of tumours after removal. The data were studied using the medical records of patients. RESULTS: Mean age was 30, 6 years (27; 34). Only 1 patient had a child at the time of diagnosis. All patients came to our clinic for a general state impairment associated to an abdominal palpable mass. The increase of the value of tumour markers was not constant. A capsular effraction was found in 3 cases with a rupture into the peritoneum. The pathology exam found 3 embryonic carcinoma and 2 seminomas, a lymph node involvement was found in 3 cases. CONCLUSION: The scarcity of these tumours should not make us ignore them. The early diagnosis of the tumour can be facilitated by testicular descent, because even if the descent of the testis does not prevent the tumour it can ease the follow-up.
