VI - Neoplasia Flashcards
Neoplasm(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.174
An abnormal mass of tissue the growth of which exceeds and is uncoordinated with that of the normal tissues and persists in the same excessive manner after the cessation of stimuli which evoked the change.
Benign(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.174
Benign or malignant?
Localized
Malignant(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.174
Benign or malignant?
Invades and destroys adjacent tissues.
Parenchyma and Stroma(TOPNOTCH)
What are the two basic components of tumors?
Parenchyma(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.174
This component of tumors largely determines its biologic behavior.
Parenchyma(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.174
This component of tumors determines the name of the growth.
Stroma(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.174
This component of tumors is crucial to the growth of neoplasms since it carries the blood supply and provides support to the growth of cells.

Benign or malignant?
Papilloma
Sarcomas(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.175
Malignant neoplasms arising in mesenchymal tissue or its derivatives.
Fibroma(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.175
Benign tumor arising in fibrous tissue is called?
Chondroma(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.175
A benign cartilagenous tumor is called?
Adenoma(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.175
This is a benign epithelial neoplasm which produces glandular patterns or neoplasms derived from glands but not necessarily exhibit glandular patterns
Papillomas(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.174
These are benign epithelial neoplasms, growing on any surface that produce microscopic or macroscopic finger-like fronds.
Polyps(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.175
A mass that projects above a mucosal surface to form a macroscopically visible structure.
Fibrosarcoma(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.175
A cancer of fibrous tissue origin.
Carcinoma(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.175
Malignant neoplasms of epithelial cell origin.
Squamous cell carcinoma(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.176
Carcinoma of squamous cell origin.
Malignant(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.176
Benign or malignant?
Lymphoma
Malignant(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.176
Benign or malignant?
Seminoma
Differentiation(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.176
The extent to which neoplastic cells resemble their normal forebears morphologically and functionally.
Anaplasia(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.177
This is considered a hallmark of malignancy, which literally means “to form backward”.
Anaplastic cells(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.177
These cells display marked pleomorphism, nuclei are variable and bizzare in size and shape. Chromatin is course and clumped. Mitoses are often numerous and distinctly atypical.
Dysplasia(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.178
This term is defined by disorderly but non-neoplastic proliferation of cells, described as a loss in uniformity of individual cells and in their architectural orientation.
Carcinoma -in- situ(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.178
Defined as dysplastic changes which involve the entire thickness of the epithelium.
False(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.178
True or false?
Dysplasia always progress to cancer.
FalseSome benign tumors are not encapsulated.(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.179
True or false?
Lack of capsule in a neoplastic growth indicates malignancy.
Metastasis(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.179
This term describes the development of secondary implants discontinuous with the primary tumor, in remote tissues.
Local invasiveness(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.179
Next to metastasis, this is the most reliable feature that distinguishes malignant from benign tumors.
SeedingLymphatic spreadHematogenous spread(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.180
Methods of dissemination of malignant neoplasms? (3)
Spread by seeding(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.180
This is the mode of dissemination of cancers of the ovary and CNS.
Lymphatic spread(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.180
This is the mode of dissemination more typical of carcinomas.
Hematogenous spread(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.180
This is the mode of dissemination more typical of sarcomas.
Sentinel lymph node(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.180
It is defined as the first lymph node in a regional lymphatic basin that receives lymph flow from a primary tumor.
Liver and lungs(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.181
What are the most common sites of metastasis involved in hematogenous dissemination of cancer?
Arsenic and its compounds(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.183
This substance is a byproduct of metal smelting, a component of alloys, electrical and semiconductor devices which could cause cancer of the lungs and skin and hemangiosarcomas.
Asbestos(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.183
This substance was formerly used for fire-resistant textiles and construction materials which could cause lung cancer and more prominently malignant mesothelioma
