Malignant giant cell tumor of soft parts. An ultrastructural study of four cases. 1977

A Alguacil-Garcia, and K K Unni, and J R Goellner

Four cases of malignant giant cell tumor of soft parts (MGCT) were studied ultrastructurally. Most of the cells in three cases were identified as undifferentiated mesenchymal cells and mononuclear monohistiocytic cells. The osteoclastlike cells seemed to arise from fusion of monohistiocytic cells. Immature fibroblastic cells, occasionally containing filaments with densities, were also present. They were scarce in three cases and predominant in the fourth. It was concluded that MGCT is a mesenchymal sarcoma with a bimorphic--monohistiocytic and fibroblastic--differentiation. MGCT is therefore considered a special variant of malignant fibrous histiocytoma.

UI	MeSH Term	Description	Entries
D008938	Mitosis	A type of CELL NUCLEUS division by means of which the two daughter nuclei normally receive identical complements of the number of CHROMOSOMES of the somatic cells of the species.

D010586	Phagocytes	Cells that can carry out the process of PHAGOCYTOSIS.	Phagocyte,Phagocytic Cell,Phagocytic Cells,Cell, Phagocytic,Cells, Phagocytic
D002479	Inclusion Bodies	A generic term for any circumscribed mass of foreign (e.g., lead or viruses) or metabolically inactive materials (e.g., ceroid or MALLORY BODIES), within the cytoplasm or nucleus of a cell. Inclusion bodies are in cells infected with certain filtrable viruses, observed especially in nerve, epithelial, or endothelial cells.

D004721	Endoplasmic Reticulum	A system of cisternae in the CYTOPLASM of many cells. In places the endoplasmic reticulum is continuous with the plasma membrane (CELL MEMBRANE) or outer membrane of the nuclear envelope. If the outer surfaces of the endoplasmic reticulum membranes are coated with ribosomes, the endoplasmic reticulum is said to be rough-surfaced (ENDOPLASMIC RETICULUM, ROUGH); otherwise it is said to be smooth-surfaced (ENDOPLASMIC RETICULUM, SMOOTH).

D005347	Fibroblasts	Connective tissue cells which secrete an extracellular matrix rich in collagen and other macromolecules.	Fibroblast
D005870	Giant Cell Tumors	Tumors of bone tissue or synovial or other soft tissue characterized by the presence of giant cells. The most common are giant cell tumor of tendon sheath and GIANT CELL TUMOR OF BONE.	Cell Tumor, Giant,Cell Tumors, Giant,Giant Cell Tumor,Tumor, Giant Cell,Tumors, Giant Cell
D006644	Histiocytes	Macrophages found in the TISSUES, as opposed to those found in the blood (MONOCYTES) or serous cavities (SEROUS MEMBRANE).	Histiocyte

D012983	Soft Tissue Neoplasms	Neoplasms of whatever cell type or origin, occurring in the extraskeletal connective tissue framework of the body including the organs of locomotion and their various component structures, such as nerves, blood vessels, lymphatics, etc.	Neoplasm, Soft Tissue,Neoplasms, Soft Tissue,Soft Tissue Neoplasm
D018219	Histiocytoma, Benign Fibrous	A benign tumor composed, wholly or in part, of cells with the morphologic characteristics of HISTIOCYTES and with various fibroblastic components. Fibrous histiocytomas can occur anywhere in the body. When they occur in the skin, they are called dermatofibromas or sclerosing hemangiomas.
