Non‐ossifying fibroma or benign lipoblastoma of bone–an electron‐microscopic and histochemical study

摘要: An ultrastructural and histochemical analysis was made of a lesion identified by light microscopy as non-ossifying fibroma bone. A histogenetic sequence traced from spindle-shaped fibroblast-like cells to multivacuolated lipoblasts with abundant glycogen. These lipid-laden showed remarkable similarity some well differentiated liposarcoma. Others have interpreted the lipid-containing representing fibroblasts which imbibed or synthesized lipid macrophages. Our studies demonstrate that this tumour consists primitive mesenchymal partial maturation early lipoblasts, suggesting its classification benign lipoblastoma
