Cards

Term

poorly defined, invasive, increased cellularity

pleomorphism

nuclei enlarged, hyperchromatic, coarse chromatin, variable nucleoli. mitosis abnormal

mesenchymal origin

spread via hematogenous route/direct invasion

presence of smooth muscle

Definition
uterus leiomyosarcoma
Term

most reliable malignancy criterion

2nd most reliable

Definition

metastasis

invasiveness

Term
what 3 sites of spreads are leiomyosarcoma of uterus
Definition

lung, bone, brain

not liver b/c drain via iliac vein to IVC.

Term
staging vs. grading
Definition

stage: TNM to assess extend of tumor spread.

grade: 1-4 to predict behavior of mal. tumor + criteria for therapy

anaplasia

rapidity of growth

degree of abnormal growth

Term

parathyroid gland

blue cells closely resembling chief cell

no pleomorphism, anaplasia, nuclear change

not a lot of adipose tissue

only 1 gland involved.

hypercalccemia

arose from glandular epithelium

do not form glands

Definition

parathyroid adenoma

not hyperplasia

endocrine tumor usually don't form gland but still adenoma

Term

cough, hemoptysis, 20 lb weight loss, hypercalcemia

nuclear enlargement nuclei, mitosis, increase in N/C

hyperchromatic nuclei, clumping, clearing of chromatin, pleomorphism, abnormal nuclcear membrane

invasive

keratin pearl + nests and sheets of polygonal cell and intercellular bridge

infiltrate into pleural cavity/mediastinal hilar lymph node

meta to brain bone liver, adenal

Definition

squamous cell carcinoma of lung

cough: bronchial irritation

hemoptysis: erosion of blood vessel

20 lb weight loss: cancer cachexia

hypercalcemia: paraneoplastic syndrome

Term

infiltrate thru wall

colonic epithelium form cohesive nest

desmoplastic response to tumor

form gland, but not goblet cell

increase CEA

cytokeratin test

Definition

colonic adenocarcinoma

not sarcoma b/c epithelium

adenocarcinoma cuz form gland

cytokeratin b/c carcinoma

Term

immunocytochemical stain on what cell

CD45

Cytokeratin

vimentin

desmin

glial fibrillary acidic protein

neurofilament protein

PSA

aFP

Definition

all leukocyte

carcinoma/epithelium

sarcoma/mesenchym

sm + skeletal m

glial

neuro

prostate

liver + testis tumor.

Term

cell not pleomorphic

anaplastic

little cytoplasm

cigar shaped

no keratin

no gland

extensive replacement by hepatocyte, many mitosis, hyperchromatasia, lack of cohesion

ACTH

green near tumor nodule

Definition

small cell undifferentiated carcinoma metastasized to liver.

green cuz bile stasis from blockage of canaliculi and small bile duct by tumor.

histologically: canalicular cholestasis via dilatation of sinusoid.

Term

menorrhagia, anemia, fatigue, , constipation, urinary frequency.

endothelial and mesothelial origin, slow, expansile, displacing adjacent tissue, not invasive, compressing but not destroying,

rare/no mitosis, nuclei resemble myometrium, no pleomorphism, no hyperchromatasia, normal nucleoli

cigar shaped, round central nuclei

Definition

leiomyomas

 

mesenchymal tumor.

 

hamartoma: disorganized mass of normal tissue, not true neoplasm.

hypertrophy: increase in size, not tumor

hyperplasia: increase in number of cell.

Term

gross: erythroplakia + leukoplakia on uvula

mitosis above basal layer of epitheliaum with lack of maturation of squamous cell

BM intact

koilocyte

Definition

carcinoma in situ via HP, not well differentiated, but if become invasive is squamous cell ca.

 

koilocyte: hypercormatic, nuclear folding and vacuoles surrounding abnormal nuclei.

Term

gross: continually enlarged lump with ulceration of lip.

invasive tumor nest replacing dermis infiltrating BM

desmoplasia isolating nests of tumor cell

keratin pearls

sheets/pavement-like nests of polygonal cell showing cellular cohesion, large amount of cytoplasm, intercellular bridge, keratinization.

no gland formation or production of mucin

stratified squamous.

great variation in size and shape.

Definition
squamous cell carcinoma, well differnetiated (not anaplastic), pleomorphic
Term

gross: white, locally invasive can, not well circumscribed, diffusing.

irregular nests

desmoplasia between

great variation in size

form nests of tumor cell

epithelial cell surrounding lumen forming glands

next to adipose cell

Definition
breast adenocarcinoma, poorly differentiated, pleiotropic (infiltrating ductal carcinoma)
Term
3 categories of heritary tumor 2 example of each
Definition

1. familial tumor: retinoblastoma (Rb), Li-Fraumani (P53), wilms

 

2. benign inherited tumor: FAP (APC)

 

3. DNA chromosomal instability syndrome:

ataxia telangiectasia -> lymphoma.

xeroderma pigmentosa -> basal cell and squamous cell ca.

 

Term

gross: necrosis, hemorrhage, brain, flattened gyri, compressed sulci and ventricle

histo: big gland tall columnar cell invading brain cell.

form gland

 

Definition
metastatic colonic adenocarcinoma to the brain, well differentiated. hematologenic route.
Term

tumor deposited in subcapsular sinus region, with anthracotic pigment

nest of tumor cell

desmoplasia

for gland

 

Definition
metastatic lung adenocarcinoma to the lymph node, well differentiated.
Term

Her-2 gene

 

c-myc gene

 

p53 gene

 

philadelphia t(9,22)

 

reciprical translocation t(8,14)

Definition

breast ca.

 

Burkitt's lymphoma

 

Li-Fraumeni

 

CML

 

Burkitt's lymphoma

Term

route:

 

renal cell carcinoma through capsule into perirenal fat. spread into renal vein into SVC to heart

Definition
direct extension
Term

route:

 

breast cecll carcinoma, desmoplasia, tumor with fat necrosis, serous and hard, on skin

Definition
