[Unusual presentation form of testicular neoplasms. Report of 5 cases]

Testicular tumors have a typical form of presentation, but there are also unusual forms that must always be considered. We report on 5 cases of testicular tumors that had an uncommon form of presentation: 3 seminomas (1 anaplastic), 1 teratocarcinoma and 1 carcinoma in situ. All testicular changes, particularly in the young male, must be suspected as being a testicular neoplasm and a complete work up must be performed until the exact diagnosis can be made. Currently, evaluation of the testes by ultrasound is a necessary procedure in the diagnosis of this pathological condition. Because it is non-invasive, simple and low-cost, it is the ideal method of evaluation.
