Ch 7 Neoplasia Flashcards
Aberrant
Deviating from the usual or natural type;
atypical.
Anaplastic
Characterized by a loss of differentiation
of cells and their orientation to one another; a characteristic of
malignant tumors.
Bence Jones proteins
Fragments of abnormal
immunoglobulins excreted in the urine of patients with
multiple myeloma.
Benign
A condition that is not life threatening, not
cancerous, not malignant.
Benign tumor
A tumor that is not malignant and
favorable for treatment and recovery.
Carcinoma
Malignant tumor of the epithelium.
Central
In oral pathology, describing a tumor or lesion
occurring within bone.
Dysplasia
Disordered growth; alteration in size,
shape, and organization of adult cells.
Encapsulated
Surrounded by a dense band of
fibrous connective tissue.
Enucleation
Complete surgical removal without
cutting into the lesion.
Erythroplakia
A clinical term used to describe
an oral mucosal lesion that appears as a smooth red patch or a
granular red and velvety patch.
Excision
Surgical removal
Hyperchromatic
Microscopic staining that is
more intense than normal.
Hyperplasia
Abnormal increase in the number of
cells in an organ or tissue.
Immunoglobulin
A protein, also called an
antibody, synthesized by plasma cells in response to a specific antigen.
In situ
confined to the site of origin without invasion to neighboring tissues
invasion
infiltration and active destruction of surrounding tissues
Leukoplakia
white plaquelike lesion that cannot be wiped off
macroglossia
enlarged tongue
malignant tumor
cancer; tumor that is resistant to treatment and can cause death; tumor with uncontrolled growth and dessimination, recurrence or metastasis
metastasis
transport of neoplasmic cells to parts of the body remote from the primary tumor and the establishment of new tumors at those sites
Mitotic Figure
A term used in microscopy to describe dividing cells observed in the process of mitosis.
Monoclonal Spike
An elevation of a single type of immunoglobulin; detected by a process called immunoelectrophoresis; seen in patients with multiple myeloma.
Neoplasia
New growth; the formation of a tumor by the uncontrolled proliferation of cells.
Neoplasm
Tumor; a new growth of tissue in which growth is uncontrolled and progressive.
Neoplastic
Pertaining to the formation of tumor by the uncontrolled proliferation of cells
Neurilemmoma
A benign peripheral nerve sheath tumor; also called a schwannoma.
Nevus
A benign tumor consisting of melanocytes (nevus cells); also a circumscribed, usually pigmented, congenital malformation of the skin or oral mucosa.
Oncogenic
Promoting tumor formation.
Odontogenic
Tooth forming.
Oncology
The study of tumors or neoplasms.
Pedunculated
Attacked by a stalk.
Peripheral
In the context of oral lesions, a term
that indicates that the lesion is within the gingival tissue or alveolar mucosa and outside the bone.
Pleomorphic
Occurring in various forms.
Primary tumor
Original tumor; the source of metastasis.
Sarcoma
Malignant tumor of the connective tissue.
Sessile
Attached by a broad base.
Trismus
Restricted jaw opening
Tumor
Neoplasm; also, a swelling or enlargement
Undifferentiated
Absence of normal differentiation; anaplasia; a characteristic of some malignant tumors.
Waldeyer Ring
A ring of lymphatic tissue formed by the two palatine tonsils, the pharyngeal tonsil, the lingual tonsil, and intervening lymphoid tissue.
