An abnormality of cells of one tissue and the morphologic result(s) of that abnormality. (An example is achondroplasia where abnormal formation of cartilage tissue results in disproportionate dwarfing).
Change in the size, shape, or organization of cells
abnormal changes in cells, possibly leading over time to cancer
Abnormality in development of cells. In pathology this is identified as alteration in size, shape and organization of adult cells.
Usually refers to a disorder in the maturation process of squamous epithelium. If the disorder is limited to the lowest 1/3 of the thickness, it is referred to as a mild dysplasia, if 2/3 then moderate dysplasia, if 3/3 or full thickness then severe dysplasia, also called carcinoma-in-situ. These changes are also referred to as intra-epithelial neoplasia Grade I, II, and III. A grade III intra-epithelial neoplasia, or a carcinoma-in-situ is considered a premalignant change that can progress to a squamous cell cancer. Dysplasias are diagnosed by microscopic examination of a biopsy specimen. (see Squamous Epithelium).
An early stage in cancer progression, which is characterized by increased cell proliferation and architectural disarray at the tissue level.
a benign but possibly precancerous condition that occurs when normal cells on the cervical surface are replaced by a layer of abnormal cells
An early stage of carcinogenesis characterized by changes in epithelial morphology.
Abnormal cervical cells that are not cancer.
An abnormal growth of cells which have some of the features of carcinoma cells but which have insufficient changes to warrant a diagnosis of carcinoma. See also atypia. Note that this is a pathological term and should be differentiated from the radiological term "dysplasia" which refers to an abnormal radiological appearance usually due to fibrocystic disease.
Any abnormality in the size, shape, or development of cells.
abnormal development, such as a congenital heart defect.
Faulty or abnormal development of a body part.
abnormal cells found on a pap smear report which shows alteration in size, shape, and organization of adult cervical cells.
alteration in size, shape, and organization of cells; may be precursor of cancer.
change in the size, shape, and organization of cells due to chronic irritation or inflammation; may revert to normal if stress is removed or may progress to neoplasia
An abnormality in the development of adult cells, leading to an alteration in cell size, shape or organisation.
Abnormal cells in the cervix, which may progress to cancer if not treated in time.
Replacement of normal cells by abnormal cells. A precancerous condition.
Abnormal changes in a cell which sometimes indicate that cancer may occur.
Condition in which cells proliferate excessively and appear abnormal in shape and orientation.
cell types in the bone marrow with an abnormal appearance.
abnormal changes or growth of cells or tissue. It occurs most often in cells that reproduce rapidly. See cervical dysplasia.
Abnormal growth or development in organs or cells
changes in the cells of the colon which can be a precursor to colorectal cancer.
an abnormality of growth.
an ATYPICAL accumulation of cells. Often considered a 'pre-cancer.' An intermediate category between HYPERPLASIA and MALIGNANT NEOPLASIA. Probably the most commonly occurring type of DYSPLASIA is that of the cervix of the uterus, where a progression from DYSPLASIA to NEOPLASIA can be clearly demonstrated. Other DYSPLASIA, such as those of the breast and prostate, are more difficult to clearly relate to NEOPLASIA at this time.
Papillomavirus Vulvovaginitis
The growth of abnormal cells.
Abnormal cells on the cervix, which in moderate to severe cases may progress to cancer if not treated.
Abnormal changes in cells, sometimes indicative of a precancerous state.
A noncancerous condition that occurs when normal cells on the surface of the cervix are replaced by a layer of abnormal cells. Dysplasia is classified as mild, moderate, severe or carcinoma in situ (CIS).
indicates a distinct abnormality of cellular development and is associated with pre-malignant disease of the cervix. It is reported as milk, moderate or sever, depending on the degree of deviation from the normal cells found on the cervix. Frozen Section: A quick pathologic test performed during surgery. Grade: Indicates the degree of cancer cell abnormality.
Abnormal development or growth.
abnormal tissue or cell growth
alterations in the cells of the colon lining seen on microscope examina-tion of a biopsy, suggesting a possible increased risk of cancer developing subsequently.
A change in the size, shape, and organization of cells. One potential cause of dysplasia of the cervix may be caused by human papillomavirus (genital or warts).
The enlargement of an organ or tissue by the proliferation of cells of an abnormal type.
Abnormal changes or growth of cells and tissues. See Cervical Dysplasia.
abnormal tissue development
altertion in size, shape and organization of cells
Abnormal in form. From the Greek dys- (bad, disordered, abnormal) and plassein (to form). For example, retinal dysplasia is abnormal formation of the retina during embryonic development.
Nausea Tyrosine Neoplasia
An abnormal growth of cells which look something like cancer cells, but do not have all the features of cancer.
An increase in both the number of cells in a tissue and in the size of those cells, a precancerous change.
An abnormality of development characterized by the loss of normal cellular architecture.
Potentially precancerous abnormality of cervical cells.
An ATYPICAL proliferation of cells. This may be loosely thought of as an intermediate category between HYPERPLASIA and NEOPLASIA. It finds its best use as a term to describe the phenomenon in which EPITHELIUM proliferates and develops the microscopic appearance of neoplastic tissue, but otherwise tends to "behave itself" and continues to line body surfaces without actually invading them, as a true malignant neoplasm would do. It may be onvenient (but not totally accurate) to consider dysplasia as a "pre-cancer" or an incipient cancer. Probably the most commonly occurring type of dysplasia is that of the cervix of the uterus, where a progression from dysplasia to neoplasia can be clearly demonstrated. Other dysplasias, such as those of the breast and prostate, are more difficult to clearly relate to neoplasia at this time.
Abnormal changes in the way tissue cells look under a microscope.
Abnormal cells that are not cancer. Back to
Cells that look abnormal under a microscope but are not cancer.
Severe Alteration In The Shape Of Cells, Pre-Cancerous
an abnormal organization of cells into tissue(s) and its morphologic result(s). In other words: a dysplasia is the process (and the consequence) of dyshistogenesis.
An ATYPICAL proliferation of cells. This may be loosely thought of as an intermediate category between HYPERPLASIA and NEOPLASIA. It finds its best use as a term to describe the phenomenon in which epithelium proliferates and develops the microscopic appearance of cancerous tissue, but otherwise tends to "behave itself" and stays on the body surface without actually invading into it. Not all doctors accept dysplasia as a concept.
(dis-PLAY-zha): Abnormal cells that are not cancer.
(Dys-bad or difficult; plasia- moulding) Dysplasia usually refers to an abnormal tissue that is not formal for that organ or part. Example, the growth of bone in the place of a soft tissue. Dysplasia may stiffen a joint making movements painful, producing chronic joint pain. Dysplastic change can be identified only through specific investigations.
an older term used to describe abnormal changes in the cervix. Dysplasia is graded mild, moderate or severe. Mild dysplasia corresponds to CIN 1, and so on.
Any abnormal development of tissues or organs.
abnormal development of cells.
A precancerous condition in which cells which are very similar to cancer cells grow in an organ but have not yet acquired the ability to invade into tissue or metastasize (spread to areas distant from where they started). This is a stage which can be cured.
abnormal development of tissue.
Abnormality in development. [ Orthodontic Glossary Preface
