Carcinoma that is marked by production of keratin
Squamous cell carcinoma
Carcinoma in urinary tract
Transitional cell carcinoma
Carcinoma in glandular epithelium
Adenocarcinoma
Usually associated with adenocarcinoma and is the tumor-induced proliferation of non-neoplastic fibrous connective tissue
Desmoplasia
Most common the adenocarcinoma of breast, pancreas and prostate
Malignant tumor of mesenchymal origin
Sarcoma
Neoplasm derived from all the three germ cell layers
Teratoma
Usually arises from ovaries and testes
Which is often encapsulated? Benign or malignant
Benign
Benign neoplasm that arises from surface epithelium and consist delicate fingerlike epithelial processes
Papilloma
Benign neoplasm of glandular epithelium
Adenoma
Benign neoplasm that is characterized by adenomatous papillary processes that extend into cystic spaces
Papillary cystadenoma
As in cystadenoma of ovary
Benign neoplasm that is marked by proliferation of connective tissue surrounding glandular epithelium
Fibroadenoma
Eg. Fibroadenoma of the breast
Most common neoplasm in women
Uterine leiomyoma or fibroid tumor
Small non neoplastic area of normal tissue misplaced withon another organ
Choristoma
T or F: Most neoplasms are polyclonal
False. Most are monoclonal. Polyclonal proliferations are almost always non-neoplastic
Most common marker used to determine clonality
Human Androgen Receptor Gene (HUMARA)
Aggressive infiltration of adjacent tissues by malignant tumor
Invasion
Extends into lymphatics and blood vessels
T or F: Presence of tumor cells within the blood vessels or lymphativs indicates metastasis
False. Indicates only penetration of the basement membrane or invasion
Malignancy that has a characteristic cannon ball appearance on CXR
Metastasis to the Lung
Preferential route of metastasis of carcinomas
Lymphatic
Preferential route of metastasis of sarcomas
Hematogenous
2 carcinomas that spread via hematogenous dissemination
Renal cell carcinoma and hepotocellular CA
Responsible for the cachexia and wasting in malignancy
TNF-a or cachectin
Cushing sundrome is a paraneoplastic syndrome of what malignancy
Small cell (oat cell) carcinoma of the lung
Production of ACTH-like substances
Inappropriate secretion of ADH is a paraneoplastic syndrome of what malignancy
Small cell carcinoma of the lung
