Pathology (Ch7-Neoplasia)

Front 1

1. neoplasia
2. oncology
3. cancer/crab
4.neoplasm

Back 1

1. new growth
2. study of tumors
3. malignant tumor
4. 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 cessation of the stimuli which evoke the change...autonomous mass, but depend on the host for their nutrition and blood supply

Front 2

1 tumours can't invade or spread to remote sites, but they can cause problems by compressing local structures

Back 2

1. benign

Front 3

1 tumors are usually round like balls

Back 3

1. benign

Front 4

A neoplasm which will compress but not invade the surrounding tissue with a non-cancer, non-precancer diagnosis

Back 4

benign tumor

Front 5

what are the characteristics of a benign tumor?

Back 5

-cells resemble normal cells and tumor
-architecture resembles that of the parent organ (well-differentiated)
-grow slowly and have few mitotic figures
-usually spherical and compress the surrounding tissue (giving rise to the appearance of a "capsule")
-never metastize

Front 6

the gross appearances of cancers usually fits one of three patterns:

Back 6

-exophytic "fungating"
-endophytic
-infiltrating

Front 7

describe exophytic cancer growth

Back 7

-"fungating"
-tumor grows as a lump, often with a cauliflower-like surface

Front 8

describe endophytic cancer growth

Back 8

tumor grows as an ulcer (the part that was probably protruding from the surface sloughed.)

Front 9

describe infiltratinng cancer growth

Back 9

tumor cells invade an organ diffusely w/o changging its shape

Front 10

any cancer is likely to exhibit [1] and/or [2], grossly and microscopically

Back 10

1. hemorrhage
2. necrosis

Front 11

in malignant tumors, cells differ [1] and [2] from normal cells, and tumor architecture is [3] organized than that of the parent tissue

Back 11

1. morphologically
2. functionally
3. less

Front 12

cancers that arise from epithelium are called?

Back 12

carcinomas

Front 13

cancers that arise from mesenchyme are called?

Back 13

sarcomas

Front 14

tumors are like [1], they all have [2] and [3]. cells usually look similar to the cells in the [4] where the tumor arose. cells will continue to perform some of the functions of the [5] organ

Back 14

1. organs
2. perenchyma
3. stroma
4. organ
5. parent

Front 15

tumours are different from organs in what ways?

Back 15

-they don't contribute to the homeostasis of the body
-they usually grow more rapidly than surrounding tissues
-some benign and all malignant tumours never cease to grow

Front 16

parenchyma

Back 16

the proliferating neoplastic cells

Front 17

the [1] determine the nature of the tumor, and the [2] is important for growth and evolution.

Back 17

1. parenchyma
2. supportive stroma

Front 18

scant [1] support produce soft and fleshy neoplasm. [2] stroma....desmoplasia

Back 18

1. stromal
2. collagenous

Front 19

epithelial tumors are named by [1] pattern (grossly appearance, protrusion into lumen etc.)

Back 19

histologic

Front 20

teratoma

Back 20

a tumor made up of a variety of parenchymal cell types, representative of more than one germ layer, usually all 3 (endoderm, ectoderm, mesoderm).
-they arise from totipotential cells
