Neoplasia Flashcards
Spread to adjacent structures
Invasion
Study of tumors or neoplasm
Oncology
Resemblance to tissue of origin
Well differentiated
Means new growth
Neoplasm
Uncontrolled, disorderly proliferation of cells, resulting in a benign or malignant
Neoplasia
Implantation into noncontiguous sites
Metastasis
Swelling but not necessarily neoplastic, but now equated with neoplasm
Tumor
Little or no resemblance
Poorly differentiated
Most defining characteristic of malignancy; less differentiated
Metastasis
Epithelial origin
Carcinoma
Poorly differentiated , pleomorphism, hyperchromatism, increase nuclear-cytoplasmic ratio, abnormal mitosis, cellular dyspolarity, often prominent nucleoli.
Anaplasia
Transitional cell epithelium of Urinary Tract
Transitional cell CA
Reversible change, often precedes malignancy
Dysplasia
Marked variability in nuclear size and shape
Pleomorphism
Aggressive but often respond well to chemo and radiotherapies.
Anaplasia
Tumor-induced proliferation of non-neoplastic Fibrous Connective tissue
Desmoplasia
