[Cystosarcoma phyllodes and sarcoma of the breast]. 1984

G A Frank, and T A Belous, and N G Bakhmutskiĭ

Altogether 217 phyllode tumours, 28 sarcomas and 5 carcinosarcomas of the mammary gland have been studied in the Institute from 1946 to 1980. Three structural variants of phyllode tumour are distinguished: 1) early stages of formation, 2) classical phyllode tumour, 3) phyllode tumour with sarcomatous stroma. 20 out of 28 sarcomas are linked with phyllode tumours while the morphogenesis of primary sarcomas, which are characterized by a more malignant clinical course, remains unclear. When studied electron-microscopically, classical phyllode tumour reveals marked and peculiar vascular proliferation which not infrequently coincides with cellular stroma. Various directions of functional and structural differentiation of stromal cells are observed. The alternation in the tumour of areas with different morphology found in light microscope is reflected by the dependence of the structure of intercellular substance upon the type of stromal cells observed electron-microscopically.

UI	MeSH Term	Description	Entries
D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy

D002296	Carcinosarcoma	A malignant neoplasm that contains elements of carcinoma and sarcoma so extensively intermixed as to indicate neoplasia of epithelial and mesenchymal tissue. (Stedman, 25th ed)	Carcinosarcomas
D003557	Phyllodes Tumor	A type of connective tissue neoplasm typically arising from intralobular stroma of the breast. It is characterized by the rapid enlargement of an asymmetric firm mobile mass. Histologically, its leaf-like stromal clefts are lined by EPITHELIAL CELLS. Rare phyllodes tumor of the prostate is also known.
