Angiotensin-I-converting enzyme (ACE) was detected in 18 germinomas, both of testicular or extratesticular localization, and studied by immunohistochemical methods using specific polyclonal antibodies and by enzyme activity measurements. ACE was also detected in normal human germ cells. On the other
High levels of angiotensin I-converting enzyme (ACE) were found by both direct radioimmunoassay and enzyme activity evaluation in a patient's plasma that had suprasellar germinoma. ACE levels returned to normal values after surgery, suggesting the tumor was the cause of the elevated plasma ACE. ACE
A case of a 32-year-old XY genotype female is described, presenting with mediastinal and abdominal lymphadenopathy and associated with an elevated serum angiotensin I converting enzyme (SACE) level. Lymph node histology showed a malignant dysgerminoma of ovarian origin. Combined chemotherapy led to
Two cases of intracranial germinoma with different clinical expression, are described. The clinical symptomatology, the diagnosis and the treatment of this tumor are discussed. The symptoms depend on the localization of the tumor: in the suprasellar germinoma endocrinologic manifestations prevail
Pathologies involving the pituitary stalk are generally revealed by the presence of diabetes insipidus (DI). The availability of MRI provides a major diagnostic contribution by enabling visualization of the site of the culprit lesion, especially when it is small. However, when only an enlarged
