Aneurysmal bone cyst
Microscopic description
The sections show cartilage, bone and osteoid with variable mineralization surrounded by fibroblasts, hemosiderin-laden macrophages, and multi-nucleated giant-cells with randomly arranged, round nuclei. Hemosiderin-laden macrophages are seen focally. There is no nuclear atypia or mitotic activity. There is no malignant appearing osteoid.
Final diagnosis
Humerous, right proximal, excision - Aneurysmal bone cyst.
