Myelolipomas are rare benign lesions composed of mature adipose tissue and immature hematopoetic cells.

The predominant location for extra-adrenal myelolipomas is the retroperitoneum, and very few reported cases describe these lesions in the peritoneal cavity. Typically ...

Pheochromocytomas are rare neoplasias of neural crest origin arising from chromaffin cells of the adrenal medulla and sympathetic ganglia (extra-adrenal pheochromocytoma). Pheochromocytoma that develop in rats homozygous for a loss-of-function mutation in p27Kip1 (MENX syndrome) show a clear progression from hyperplasia to tumor, offering the possibility to gain insight into tumor pathobiology....
In another paper of this series (1) it was demonstrated that most patients undergoing surgery developed increased plasma levels of 17-hydroxycorticosteroids.
