Flashcards in August 11, 2015 - Introduction to Neoplasia Deck (15):
1

Adeno

Glandular

2

Chondro

Cartilage

3

-oma

Benign (usually)

4

-carcinoma

Malignant (usually) in epithelial tissue.

5

-sarcoma

Malignant (usually) for mesenchymal tissues.

6

Lymphoma

Malignant 'tumor' of the lymphoid cells.

NOT benign.

7

Melanoma

Malignant tumor of melanocytes.

NOT benign.

8

Mesothelioma

Malignant tumor of mesothelium.

NOT benign.

9

Seminoma

Malignant tumor of the testis.

NOT benign.

10

Choristoma

NOT a tumor.

Heterotopic rests of tissue found in another part of the body.

11

Teratoma

Germ cell tumor from totipotent progenitor. These contain more than one cell type and frequently include teeth, hair, sebaceous secretions, etc.

Mature teratoma is BENIGN

Immature teratoma is MALIGNANT

12

Anaplasia

The lack of differentiation.

 

This is a hallmark of malignancy. The less differentiated a cell is, the more malignant or advanced that cancer is.

13

Latency Period of Cancer

Can hang around for a long time. Potentially up to 25 years. 

 

If patients have a previously diagnosed malignancy, no matter what, metastatic disease must ALWAYS be on the differential diagnosis if a new tumor appears.

14

7 Features of Cancer

1. Suf-sufficiency in growth signals

2. Insensitivity to growth inhibitory signals

3. Evasion of apoptosis

4. Limitless replicative potential

5. Sustained angiogenesis

6. Ability to invade and metastasize

7. DNA repair defects
