<prompt> A tumor that follows the rule of 10 is-PheochromocytomaOncocytomaLymphomaRenal cell carcinoma  <response>: Pheochromocytomas usually subscribe to a convenient rule of 10s :-10 of pheochromocytomas arise in association with one of several familial syndromes. These include the MEN-2A MEN-2B syndromes, type I neurofibromatosis, von Hippel-Lindau syndrome Sturge-Weber syndrome.10 of pheochromocytomas are extra-adrenal, occurring in sites such as organ of Zuckerkandl carotid body, where these chromaffin-negative tumors are usually called paragangliomas to distinguish them from pheochromocytomas.10 of nonfamilial adrenal pheochromocytomas are bilateral; this figure may rise to 70 in cases that are associated with familial syndromes.10 of adrenal pheochromocytomas are biologically malignant, although the associated hypertension represents a serious potentially lethal complication of even benign tumors.10 of adrenal pheochromocytomas arise in childhood, usually the familial subtypes, and with a strong male preponderance. The nonfamilial pheochromocytomas most often occur in adults between 40 60 years of age, with a slight female preponderance.
