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.
Burnt-out chronic osteomyelitis
GREAT TOE, LEFT, AMPUTATION: - SKIN WITH ULCERATION AND IMPETIGINIZATION. - ATHEROSCLEROSIS, MODERATE-TO-SEVERE. - SOFT TISSUE WITH FIBROSIS AND CHRONIC INFLAMMATION. - BONE AND MILDLY FIBROTIC MARROW SPACE WITH SCATTERED LYMPHOCYTES AND SIDEROPHAGES; NO SIGNIFICANT NUMBERS OF PLASMA CELLS OR NEUTROPHILS APPARENT. - NEGATIVE FOR DYSPLASIA AND NEGATIVE FOR MALIGNANCY.
