Unusual Forms of Adrenal and Extra-Adrenal Myelolipomas.
Myelolipomas are rare benign tumors of poorly understood tumorigenesis composed of mature hematopoietic tissue and fat. They mostly occur in the adrenal glands, but extra-adrenal myelolipomas have been reported in other locations such as the presacral region or retroperitoneum. It is not unusual that they are incidental findings revealed in the study of different diseases. We report 3 unusual examples of myelolipomas. The first is a multiple, unusually large, extra-adrenal myelolipoma, presented as an autopsy finding in an individual who had died suddenly from a central nervous system hemorrhage. The remaining 2 were incidental findings in patients studied for different reasons. Both were located within another neoplasm, namely an adrenal adenoma and a liver focal nodular hyperplasia. Moreover, the first showed infiltration by a non-Hodgkin lymphoma.
