Tumor - properties, structural features, Morphogenesis and histogenesis
Topic Titles: “Tumor, properties, structural features of tumor tissue ” (SIWT) “ Morphogenesis and histogenesis of tumor - Histogenetic classification” (PL) About Tumor Benign tumors Malignant tumors Type of growth depending on the degree of differentiation Expansive Infiltrative Types of atypism, briefly explain their essence Tissue:- tissue atypism is characterized by impaired organotypic and histotypic differentiation and the ratio of parenchyma and stroma of tumor tissue, morphological properties of cells maintain and its histogenesis may be determined. Tissue and cellular: - cellular atypism are impaired cytotypic differentiation and the appearance of atypical cells with their polymorphism. Sometimes the differentiation of tumor tissue is significantly disturbed, making it difficult to determine their histogenesis. Relapses, briefly explain their nature No (usually) because in the starting phase or benign tumor don`t spread or very slow growth. Yes (usually) because in thi...
