1. This slide shows the microscopic appearance of a tumor found in the adrenal gland.
a. this tumor is sometimes accompanied by other endocrine neoplasms.
b. this tumor is one of the causes of hypertension.
c. this tumor is more often benign than malignant.
d. a tumor of this kind may arise outside the adrenal gland.
e. all of the above statements are correct.
1.E. is CORRECT!
This is a pheochromocytoma, a tumor arising most commonly in adrenals, but about 15% of pheochromocytomas originate in the extraadrenal paraganglia. A majority of tumors are benign, but 20 - 40% of extraadrenal tumors are malignant. About 10% of tumors are associated with other neoplasms. Pheochromocytoma is a rare cause of hypertension, which is cured by the removal of the tumor.
