[Synchronic bilateral testicular seminomas. Ultrasound diagnosis].

Objectives: To report a new case of bilateral synchronic testicular tumors, and to perform a bibliographic review on the topic, emphasizing the ultrasound characteristics and oddity of these presentation, which accounts for less than 1% of germ cell testicular tumors.

Methods/results: 29-year-old patient consulting because of an increase of the testicular size over one year. Physical examination and ultrasound revealed a synchronic neoplastic involvement of the testicles, suggesting the radiological diagnosis of bilateral "seminomatous tumor", with "non seminomatous" foci in one of them.

[Primary ureteral leiomyosarcoma: a rare cause of obstructive uropathy].

Objectives: Transitional cell carcinoma is the most frequent primary malignant neoplasia obstructive ureteral pathology. Nevertheless, obstructive primary ureteral leiomyosarcoma (stromal tumour) is an unusual disease, diagnosed by histopathological examination of nephroureterectomy surgical specimens.

Methods/results: We report a case of ureteral obstructive uropathy in a 38-year-old woman, with non functional left kidney.
