Table 3.1 Examples of Tumor Nomenclature
Other connective tissues is mesencyhmal. What are 3 major cell types of the other type of connective tissues?
1...Fibroblasts: capsules, fascia, tendons, ligaments... 2...Mesothelium: signle cuboidal epithelium of body cavities and spaces (peritoneal cavity, snyovial cavity of knee joint)... 3...Adipocytes: storage for lipids
Lymphocyte tumors are always malignant; there are NO benign lymphocytic tumors. What are lymphocytes?
B cells, T cells, Natural Killer Cells.
Circulatory and lymphatic tissue are mesencyhmal. What is the major cell type of the Circulatory and lymphatic system?
Endothelium - inner surface vessels (arteries, veins, capillaries, lymphatics)
Epithelial tumors can be benign or malignant. What is epithelial tissue?
Epithelial tissue lines cavities and surfaces of blood vessels and organs
What are 2 malignant tumors that arise in lymphocytes?
Leukemia Lymphoma
Leukemia and Lymphomas are malignant tumors that arise in lymphocytes. What is the difference between the two?
Leukemia: cancer cell is in bone marrow and blood... Lymphoma: cancer is in lymph node, lymphatic tissue, or other tissues
Musculoskeletal tissue is mesencyhmal. What are the major cell types of the musculoskeletal system?
Muscle (myoblasts) Bone (osteoblast) Cartilage (chondroblast)
What are 2 examples of malignant tumors arising from epithelial tissue?
adenocarcinoma papillary carcinoma
What are examples of 2 benign tumors arising from epithelial tissue?
adenoma papilloma
Papillomas are benign tumors of epithelial origin. What are papillomas?
benign tumors growing exophytically or outwardly projecting in nipple-like and finger like fronds (leaf-like)... Examples (skim): skin, oral cavity, pharynx, vagina, cervix, urothelium, and lactiferous duct
Adenomas are benign tumors of epithelial origin. What are adenomas?
benign tumors of glandular epithelium... parenchyma organs with endocrine and exocrine secretion and mucosa of hollow organs
Papillary carcinomas are malignant tumors of epithelial origin. What are papillary carcinomas?
growing exophytically or outwardly projecting in nipple-like and finger like fronds (leaf-like)... classic example is papillary thyroid cancer (follicular thyorid cancer)
What is an example of benign tumor arising from mesenchymal tissue?
lipoma benign tumor of fat cells below skin
What is an example of a malignant tumor arising from mesenchymal tissue?
liposarcoma malignancy of fat cells in deep soft tissue (i.e. inside of thigh or retroperitoneum)
Adenocarcinomas are malignant tumors of epithelial origin. What are adenocarcinomas?
malignant tumor formed from glandular structures in epithelial tissue...
Melanocytic tumors are benign and malignant. What are melanocytes?
melanin-producing skill located in stratum basale of epidermis, middle layer of eye (uvea), inner ear, meninges, bones and heart... melanin is pigment responsible for forming skin color
What is an example of a malignant tumor arising from melanocytes?
melanoma... malignant (cancer) cells form in melanocytes
What is an example of a benign tumor arising from melanocytes?
nevus (moles)... moles are small, dark bown spots or growths on skin caused by clusters of pigmented cells or melanocytes
Mesenchymal tumors can be benign or malignant. What is mesenchymal tissue? What 4 tissue constitute mesenchymal tissue?
soft tissue or connective tissue derived from mesoderm Tissues of 1) musculoskeletal system 2) circulatory system 3) lymphatic system 4) other connective tissues
