Study Notes
Tumor Characteristics
- The presence of well-defined nidi of small uniform cells characterizes a follicular pattern.
- Carcinoma in-situ is defined as a neoplasm that remains confined to the epithelium of origin without penetrating the basement membrane.
- Dysplasia is distinguished from hyperplasia and carcinoma in-situ by the presence of cytologic atypia and loss of normal tissue architecture.
Tumor Spread
- Tumors that develop through lymphatic spread are known as lymph node metastases.
- Paraneoplastic syndromes are systemic effects that accompany malignant disease, but are not directly related to the primary tumor.
Tumor Types
- Tumors favored through hematogenous spread are those that metastasize through the bloodstream.
- Benign tumors that produce a microscopic or macroscopic finger-like pattern are known as papillary tumors.
- Malignant tumors that arise from mesenchymal tissue are known as sarcomas.
Tumor Histology
- Hyperplasia is distinguished from dysplasia by the presence of normal tissue architecture.
- The characteristic feature of microfollicular pattern is the presence of small, uniform follicles.
- Pleomorphism refers to the variation in cell size and shape.
- Anaplasia refers to the loss of differentiation in tumor cells.
Neoplasia
- Neoplasia is defined as the uncoordinated growth of cells that is not in harmony with normal tissues.
- The study of tumors is called oncology.
Tumor Components
- The two basic components of a tumor are the parenchyma and stroma.
- The biological behavior of a tumor is primarily determined by the parenchyma.
Tumor Nomenclature
- The suffix '-oma' in the nomenclature of tumors indicates a benign tumor.
- 'Fibro + oma' in nomenclature indicates a tumor originating from fibrous tissue.
- 'Chondro + oma' in nomenclature indicates a tumor originating from cartilaginous tissue.
- 'Leiomyo + oma' in nomenclature indicates a tumor originating from smooth muscle tissue.
