Figure 5. (A) Histologic evaluation of the left humerus (20×) shows a pauci-cellular mass consisting of extensive eosinophilic fibrin-like deposits and cholesterol clefts. (B) Left tibia (20×) showing the bland histologic features of the cyst wall. (C) Intermediate power of the right tibia (100×) displays both the bland cyst wall, fibrin-like deposits, and the cholesterol clefts. (D) Identical morphology is also seen in the right third metacarpal (100×) with the serpiginous architecture of eosinophilic fibrin-like deposits.
