the tumor, node, metastasis
TNM - system of staging used to identify the invasiveness of the malignant tumor
- Grade 1
-
the tumor cells are well differentiated
close resemblance to tissue of origin, thus retaining some specialized functions - Grade II
-
tumor cells moderately differentiated
less resemblance to tissue of origin
more variation in size and shape of tumor cells
increased mitoses - Grade III
- tumor cells poorly to very poorly differentiated
- Grade IV
-
tumor cells very poorly differentiated
little or no resemblance to tissue of origin
extreme variation in size and shape of tumor cells - T0
- no evidence of tumor
- what are the designations for TNM?
-
T0
Tis
T1, T2, T3, T4 - Tis
-
Stage I
carcinoma in situ indicates the tumor is in a defined location and shows no invasion into surrounding tissues - T1, T2, T3, T4
-
Stage II
Primary tumor size and extent of location invasion, where TI is small with minimal invasion and T4 is large with extensive local invasion into surrounding organs and tissues - what are the designations for Nodes
-
N0
N1, N2, N3, N4 - N0
- regional lymph nodes show no abnormalities
- N1, N2, N3, N4
-
Stage III
degree of lymph node involvement and spread to regional lymph nodes, where N1 is less involvement with minimal spreading and N4 is more involvement with extensive spreading - what are the designations for metastasis?
-
M0
M1 - M0
- no evidence of metastasis
- M1
- Stage IV
- abscess
- localized collection of pus at the site of an infection
- alopecia ****

-
damaged tissue following a sever burn
*turtle shell like - must be cut off - impetigo
- bacterial skin infection characterized by isolated pustules that become crusted and rupture
- keratosis
- thickened area of the epidermis or any horny growth on the skin (such as a callus or wart)
- kerat
- horny tissue, hard
- pallor
- unnatural paleness or absence of color in the skin
- pediculosis
- infestation with lice, transmitted by personal contact or common use of brushes, combs or headgear
- pedicul
- lice
- petechia
- minute, pinpoint hemorrhage under the skin
- pressure ulcer
- skin ulceration caused by prolonged pressure from lying in one position that prevents blood flow to the tissues, usually in bedridden patents
- pruritus
- intense itching
- psoriasis
- chronic skin disease characterized by circumscribed red patches covered by thick, dry, slivery, adherent scales caused by excessive development of the basal layer of the epidermis
- scabies
- contagious skin disease transmitted by the itch mite, commonly through sexual contact
- tinea
-
fungal skin infection whose name commonly indicates the body part affected
*ringworm - vitiligo
- localized loss of skin pigmentation characterized by milk-white patches
- intradermal
- skin test that identifies suspected allergens by subcutaneiously injecting small amounts of extracts of the suspected allergens and observing the skin for a subsequent reacion
- patch
- skin test that identifies suspected allergens by topical application of the substance to be tested, usually on the forearm and observing for reaction
- scratch (prick)
- skin test that identifies suspected allergens by placing a small quantity of the suspected allergen on a lightly scratched area of the skin
- debridement
-
removal of necrotized tissue from a wound by surgical excisions, enzymes, or chemical agents
(burn patients) - skin graft
- surgical procedure to transplant healthy tissue by applying it to an injured site
- allograft
-
transplantation of healthy tissue from one person to another person
AKA homograft - autograft
-
