Case Discussion

Paragangliomas are rare neuroendocrine tumors arising from paraganglia, and abdominal extra-adrenal paragangliomas usually originate from the organ of Zuckerkandl.

It should notice that malignancy is defined as evidence of metastases, and histopathologically there are no reliable markers of malignant potential.
