CH 19 Oncology Flashcards
Forming large open spaces with fluid.
Cystic
Mushrooming patter of growth in which tumor cells pile on top of another and project from a tissue surface.
Fungating
Having the features of inflammation (redness, swelling, and heat).
Inflammatory
Large, soft, fleshy tumors.
Medullary
Containing dead tissue.
Necrotic
Characterized by an open, exposed surface from the death of overlying tissue.
Ulcerating
Resembling a wart-like growth.
Verrucous
Tumor cells form patterns resembling small sacs; commonly found in tumors or muscle, bone, fat, and cartlidge.
Alveolar
Referring to localized tumor cells that have not invaded adjacent structures.
Carcinoma in situ
Spreading evenly throughout the affected tissue.
Diffuse
Containing abnormal-appearing cells that are not clearly cancerous.
Dysplastic
Resembling squamous epithelial cells (thin, plate-like), often occurring in the respiratory tract.
Epidermoid
Forming glandular sacs.
Follicular
Forming small, finger like or nipple-like projections of cells.
Papillary
Composed of a variety of types of cell.
Pleomorphic
Densely packed tumors, due to bands of fibrous tissue.
Scirrhous
Lacking microscopic structures typical of normal mature cells.
Undifferentiated
Disctruction of tissue by burning.
Cauterization
Placement of a large bore needle that extracts a thin core of tissue.
Core needle biopsy
Use of subfreezing temperatures to destroy tissue
Cryosurgery
Tumor is removed along with a large areaof surrounding tissue containing lymph nodes.
En bloc resection
Removal of tumor and a margin of normal tissue . Provides a specimen for diagnosis or can be curative for small noninvasive tumors.
Excisional biopsy
Wide resection involving removal of the tumor, its organ of origin, adn all surrounding tissue.
Exteneration
Placement of a very thin needle inside the tumor mass and extracting cells for microscopic.
Fine needle aspiration
