An Unusual Fat-Containing Presacral Tumor in an Elderly Patient
Figure 5
84-year-old male with presacral myelolipoma. Microscopic examination: the tumor was composed of varying amounts of mature adipose tissue admixed with hematopoietic elements ((a) and (b): H&E, x40); there were also dispersed hemorrhagic areas ((c): H&E, ×40). In higher magnification view the presence of the three cell lineages (myeloid, erythroid, and megakaryocytic) was evident, similarly to the normal bone marrow ((d): H&E, ×400).
