Incidental Discovery of Testicular Microlithiasis: What Is the Importance of Ultrasound Surveillance? Two Case Reports
Many studies have demonstrated an association between diffuse bilateral testicular microlithiasis (TM) and gonadal and extragonadal germ cell tumors. Nevertheless, it is still uncertain whether ultrasound surveillance is really necessary in patients with TM in the absence of other risk factors such as previous testicular cancer, a history of cryptorchidism or testicular atrophy. We report the c...
متن کاملRadiology of primary intracranial yolk-sac (endodermal sinus) tumors.
Most primary intracranial germ-cell tumors are germinomas and teratomas. Less frequent are embryonal carcinomas, choriocarcinomas, and yolk-sac (endodermal sinus) tumors in various admixtures and degrees of purity. Teilum [1] first used the term endodermal sinus tumor in 1959 to describe those tumors (whether ovarian, testicular, or extragonadal) that originate in primitive germ cells of extrae...
متن کاملExtragonadal germ cell tumour with the "burned out" phenomenon mimicking a retroperitioneal tumour of neurogenic origin.
OBJECTIVE To describe a case of retroperitoneal metastasis of a gonadal germ cell tumour with the "burned-out" phenomenon in a 35 year old patient with a suspected diagnosis of retroperitoneal tumour of neurogenic origin. METHODS With the clinical and radiological suspicion of retroperitoneal tumour of neurogenic origin the tumour was removed, via the retroperitoneal space. RESULTS Patholo...
متن کاملExtragonadal retroperitoneal germ cell tumor: primary versus metastases?
OBJECTIVE Primary extragonadal germ cell tumors are rare and their histogenetic origin is not clear. We describe two cases presenting as primary retroperitoneal germ cell tumors without clinical evidence of testicular tumor. METHODS A 21 and 18 years-old patients presented retroperitoneal choriocarcinoma and yolk sac tumor, respectively. In both cases, testicular palpation was not suspicious ...
متن کاملTesticular seminoma after the complete remission of extragonadal yolk sac tumor : Case Report
Background: Between 2% and 5% of malignant germ-cell tumors in men arise at extragonadal sites. Of extragonadal germ cell tumors, testicular carcinoma in situ (CIS) are present in 31-42% of cases, and CIS are reported to have low sensitivity to chemotherapy in spite of the various morphology and to have a high likelihood of developing into testicular tumors. A testicular biopsy may thus be high...
