Retroperitoneal extra-adrenal paraganglioma: a rare but important diagnosis

Irish Journal of Medical Science, 2008
Extra-adrenal paragangliomas of the retroperitonium are infrequently diagnosed. Their malignant behaviour cannot be predicted on initial clinical and histological assessment. These tumours have higher propensity for subsequent metastasis compared with pargangliomas at other sites.We aim to describe a case report of an incidental finding of left ...

Asymptomatic extra-adrenal paraganglioma masquerading as retroperitoneal sarcoma

A low-density nodule was detected in the left adrenal gland, 10 mm in diameter.

Molecular and cellular biology of pheochromocytomas and extra-adrenal paragangliomas

Endocrine Pathology, 2006
Efforts to understand the pathobiology of pheochromocytomas and extra-adrenal paragangliomas have been spurred by genetic and gene expression profiling studies showing genotype-phenotype correlations in familial pheochromocytoma/paraganglioma syndromes and in some sporadic tumors.
