How is wound healing different from the development of a neoplasm?
|
Wound healing involves tightly controlled growth. Neoplasm is uncontrolled proliferation that outlasts the initial stimulus.
|
|
Literal definition of tumor.
|
Swelling.
|
|
What are the two types of neoplasm?
|
Benign - localized tumor. Malignant - invasive tumor that can metastasize.
|
|
What are the hallmark features of a malignant neoplasm?
|
Cells that can invade and metastasize.
|
|
The “-oma” ending USUALLY indicates a __ tumor.
|
Benign.
|
|
Name two tumors that end in “-oma” but are malignant.
|
Sarcoma. Carcinoma.
|
|
There is no such thing as __ cancer.
|
Benign.
|
|
What biochemical changes can make a tumor firm and immovable upon palpation?
|
Increases cytokines, which support the tumor.
|
|
Sarcoma = ?
|
Mesenchymal-derived tumor.
|
|
Carcinoma = ?
|
Epithelium-derived tumor.
|
|
Neoplasm = ?
|
New growth that shows uncontrolled proliferation.
|
|
Name three “-omas” that are NOT neoplastic.
|
Harmatoma - disorganized mature tissue. Choristoma - well-organized, displaced tissue. Granuloma - chronically inflamed tissue. Hematoma - capillary collection.
|
|
These tumors sound benign but are malignant.
|
Lymphoma, myeloma, seminoma, melanoma, hepatoma, glioma.
|
|
Fibroma = ?
|
CT derived tumor.
|
|
Endothelial derived tumor.
|
Hemangioma, angiosarcoma.
|
|
Muscle derived tumor.
|
Leiomyoma and rhabdomyoma.
|
|
Adenocarcinomas resemble __ tissue.
|
Glandular tissue.
|
|
Where are transitional cell carcinomas found?
|
Found in urinary bladder, ureter, and renal pelvis.
|
|
A keratin pearl indicates a __ __ carcinoma.
|
Squamous cell carcinoma.
|
|
Mixed neoplastic tumors consist of __ and __ tissues.
|
Epithelium and mesenchymal.
|
|
Compound tumors consist of ?
|
More than one neoplastic cell type and derived from more than one germ layer.
|
|
__ is a compound tumor that can be malignant or benign.
|
Teratoma.
|
|
__ teratoma is benign but __ and __ teratomas are usually malignant.
|
Mature teratoma of the ovary - benign. Embryonal teratoma and teratoma of the testis is usually malignant.
|
|
Benign neoplasm = ?
|
Tumor that does not metastasize and is differentiated.
|
|
How do benign tumors cause problems?
|
Secreting a substance, compression of other structures, and some may become malignant.
|
|
What are the hallmarks of malignancy?
|
Invasion and metastases.
|
|
Which tumor has cells that more closely resemble the cell of origin?
|
Benign.
|
|
What two organs typically receive the most metastases?
|
Liver and lungs.
|
|
What is the nuclear:cytoplasmic ratio for benign and malignant tumors?
|
Benign - low N:C. Malignant - high N:C.
