Neoplasm Intro and Benign Growth

Stork bites

________ are NOT hemangiomas, they are harmless nevus simplex, dilated capillaries, and typically fade with time.

Mortality

________: how many people die from it.

Hamartomas

________: are "tumors "but NOT neoplasms, they are a disorganized overgrowth of different cells and tissues not normally found in an organ.

onkos

Oncology: the study of neoplasms, comes from the "________ "(a bulging mass)

Biological Behavior

________ of benign neoplasms: slow growth, often encapsulated, no metastasis, non- destructive.

proliferating "tumor" cells and supporting stroma with connective tissue and vessels.

Tumors have 2 basic components

Papillomas

________ arise from surface epithelium (skin, mouth, gut, bladder), usually are "finger- like "projections, and have various causes (HPV (CONTAGIOUS), warts, viral infections)

Neoplasms

________ are neoplastic growth with the uncontrolled or disorderly proliferation of cells resulting in benign or malignant tumors.

undifferentiated, uncontrolled growth, invasion of tissues around them, metastasis.

Malignant tumor

Hemangiomas

________: begin tumors of the vascular epithelium (color tells depth)

Resembles original tissue, grows slowly, does NOT metastasize, often encapsulated, does NOT invade and destroy.

Benign Neoplasms

Cherry Angiomas

________: AKA senile angiomas, occur with age.

Infantile Hemangiomas

________: most frequent- (4- 5 % of newborns), appear at 4- 6 weeks, grow quickly, and then disappear.

Hamartomas

________ are NOT a neoplastic proliferation of 1 cell type.

Neoplasia

"new growth"

Oncology

the study of neoplasms, comes from the "onkos" (a bulging mass)

Benign Neoplasms

Resembles original tissue, grows slowly, does NOT metastasize, often encapsulated, does NOT invade and destroy

Malignant Neoplasms

undifferentiated, uncontrolled growth, invasion of tissues around them, metastasis

Incidence

how many people get it

Mortality

how many people die from it

Biological Behavior of benign neoplasms

slow growth, often encapsulated, no metastasis, non-destructive

Nevus

the most common benign tumor, a pigmented mole, the proliferation of melanocytes

Hemangiomas

begin tumors of the vascular epithelium (color tells depth)

Infantile Hemangiomas

most frequent (-4-5% of newborns), appear at 4-6 weeks, grow quickly, and then disappear

Congenital Hemangiomas

less frequent, present at birth, may remain or shrink or go pale

Cavernous Hemangiomas

are most often congenital

Cherry Angiomas

AKA senile angiomas, occur with age

Hamartomas

are "tumors" but NOT neoplasms, they are a disorganized overgrowth of different cells and tissues not normally found in an organ

Adenomas

arise from glandular epithelium (colonic polyps, thyroid, liver)
