Neoplasia I Flashcards
process of uncontrolled growth
neoplasia
abnormal mass of tissue
neoplasm
accumulation of cells due to proliferation and or evasion of apoptosis
neoplasia
grwoth exceeds and is uncoordinated with normal tissue
neoplasm
locally invasive with no tendency for metastasis
intermediate tumor
pre-invasive cell proliferation with cytological features of malignancy
carcinoma in situ (dysplasia)
determines biologic behavior
parenchyma
tumor derives its name based on the
parenchyma
determines growth and evolution of tumor

disorganized growth of tissues normally found at a given site
choristoma
not a tumor
normal tissue in a foreign location
capsule generally absent
malignant
rapid growth
malignant
more common malignat
carcinoma
better prognosis malignant
carcinoma
distant metastais presents earlier
sarcoma
initial mode of spread to blood )hematogenous)
sarcoma
initial spread to lymphatic
carcinoma
hematopoietic cell cancer (bone marrow stem cells)
leukemia
lymphoid tissue cancer
lymphomas
most common extranodal site for a primary malignant lymphoma
stomach
most common adult leukemia and overall leukemia
CLL chronic lymphocytic leukemia
most common childhood leukemia and cancer
acute lymphocytic leukemia ALL
tumor composed of more than one parenchymal cell type and erived from more than one germ layer
teratoma
benign teratoma
mature teratoma
malignant teratoma
immature teratoma
poorly differentiatied tumro
malignant
well-differentiatied tumora
malignant or benign
pulmonary hamartoma
firm and discrete lesion
often have calcifications
most are small
coin lesion

peutz-jeghers syndrome
hamartoma
