- Discussion:
- mixture of benign stromal tissue
- large
vascular lacunae separated by septa in which numerous giant cells are found & & filled with clotted blood (blood-filled spaces with bland fibrous connective tissue septa) that resembles cranberry sauce;
- cavernous spaces vessel lack walls & normal features of blood vessels;
- stroma has histiocytes, fibroblasts, scattered giant cells, hemosiderin, and occasional inflammatory cells;
-
giant cells
- ABC may be difficult to distinguish from that of
GCT of bone;
- large amounts of hemosiderin;
- Secondary Aneuysmal Bone Cysts;
- occur in conjunction w/ other lesions (eg,
chondroblastoma,
osteoblastoma,
osteosarcoma,
EOG,
nonossifying fibroma);
Giant-cell reparative granuloma of the hand and foot bones.
