What is the difference between hyaline degeneration and hydropic degeneration?
hepatolenticular degeneration Wilson's disease. hyaline degeneration a regressive change in cells in which the cytoplasm takes on a homogeneous, glassy appearance; also used loosely to describe the histologic appearance of tissues. hydropic degeneration a form in which the epithelial cells absorb much water.
What does degeneration mean in medical terms?
[de-gen″ĕ-ra´shun] deterioration; change from a higher to a lower form, especially change of tissue to a lower or less functionally active form. When there is chemical change of the tissue itself, it is true degeneration; when the change consists in the deposit of abnormal matter in the tissues, it is infiltration. adj., adj degen´erative.
What is hyaline degeneration in histology?
hyaline degeneration a regressive change in cells in which the cytoplasm takes on a homogeneous, glassy appearance; also used loosely to describe the histologic appearance of tissues. hydropic degeneration a form in which the epithelial cells absorb much water.
What is the difference between Infiltration and degeneration?
deterioration; change from a higher to a lower form, especially change of tissue to a lower or less functionally active form. When there is chemical change of the tissue itself, it is true degeneration; when the change consists in the deposit of abnormal matter in the tissues, it is infiltration. adj., adj degen´erative.
What causes Hydropic degeneration?
Hydropic degeneration is a result of ion and fluid homestasis that lead to an increase of intracellular water. The vacuolated swelling of the cytoplasm of the hepatocytes of the GNPs treated rats might indicate acute and subacute liver injury induced by the GNPs.
What is Hydropic degeneration pathology?
Hydropic degeneration is a term used to express the swelling that occurs in injured cells by an influx of water. This term usually refers to an injury of certain liver or kidney cells. Hydropic degeneration is an early indicator of cellular degeneration in response to an injury.
What does Hydropic mean?
Medical Definition of hydropic 1 : exhibiting hydrops especially : edematous. 2 : characterized by swelling and taking up of fluid —used of a type of cellular degeneration.
What is Hydropic degeneration in molar pregnancy?
Hydropic degeneration of the placenta is a phenomenon where numerous cystic spaces are formed within the placenta which is often accompanied by placental enlargement. It can occur in a number of situations which include. simple hydropic degeneration in 1st trimester pregnancy loss - fetal demise.
What is Hydropic degeneration is it reversible or not Briefly explain your answer?
Cellular swelling (synonyms: hydropic change, vacuolar degeneration, cellular edema) is an acute reversible change resulting as a response to nonlethal injuries. It is an intracytoplasmic accumulation of water due to incapacity of the cells to maintain the ionic and fluid homeostasis.
What are Hydropic changes?
Hydropic change is one of the early signs of cellular degeneration in response to injury. Hydropic change refers to the accumulation of water in the cell.
Do hydrops babies survive?
The prognosis for babies with hydrops fetalis depends on the underlying cause of the condition. Overall, however, the survival rate is low. More than half of all babies with the condition die before birth or soon after delivery.
Is hydrops genetic?
A series of 1790 fetal and neonatal autopsies performed between 1976 and 1988 were retrospectively investigated for the presence of hydrops. Thirty (5.5%) and 35 (2.8%) cases of hydrops were found in the groups of fetal and neonatal autopsies, respectively. Genetic causes accounted for 35%.
How common is hydrops?
Hydrops fetalis only occurs in 1 out of every 1,000 births. If you are pregnant and your baby has hydrops fetalis, your doctor may want to induce early labor and delivery of the baby. A baby born with hydrops fetalis may need a blood transfusion and other treatments to remove the excess fluid.
What is a Hydropic placenta?
Definition. An abnormality of the placenta in which there are numerous cystic spaces within the placenta as well as placental enlargement. [
What is Cytotrophoblast and Syncytiotrophoblast?
Cytotrophoblasts and syncytiotrophoblasts. Trophoblasts (from Greek to feed: threphein) are cells forming the outer layer of a blastocyst, which provides nutrients to the embryo, and develops into a large part of the placenta.
What is partial hydatidiform mole?
A partial molar pregnancy is a variation of a molar pregnancy, an abnormal pregnancy in which an embryo (the fertilized egg) either develops incompletely, or doesn't develop at all. Instead, a cluster of grape-like cysts (known as a hydatidiform mole) grows in the uterus.
What is a Hydropic placenta?
Definition. An abnormality of the placenta in which there are numerous cystic spaces within the placenta as well as placental enlargement. [
What is placenta degeneration?
Simple hydropic degeneration of the placenta is a form of hydropic degeneration of the placenta that can occur in a first trimester pregnancy loss. In this situation, the serum beta HCG will tend to be low and tend to show a decline with repeat testing.
What is cell degeneration?
Nonlethal injury to a cell may produce cell degeneration, which is manifested as some abnormality of biochemical function, a recognizable structural change, or a combined biochemical and structural abnormality. Degeneration is reversible but may progress to necrosis if injury persists.
What is hyaline degeneration?
Medical Definition of hyaline degeneration : tissue degeneration chiefly of connective tissues in which structural elements of affected cells are replaced by homogeneous translucent material that stains intensely with acid stains.
What are the only significant lesions in the kidneys?
Histologically, the only significant lesions are vacuolar hydropic degeneration and pyknosis of the epithelial cells in the distal convoluted tubes of the kidneys (PASSOS, 1983).
What is the term for a regressive change in cells in which the cytoplasm takes on a?
hepatolenticular degeneration Wilson's disease. hyaline degeneration a regressive change in cells in which the cytoplasm takes on a homogeneous, glassy appearance; also used loosely to describe the histologic appearance of tissues. hydropic degeneration a form in which the epithelial cells absorb much water.
What is hydropic degeneration?
hydropic degeneration a form in which the epithelial cells absorb much water. lattice degeneration of retina a frequently bilateral, usually benign asymptomatic condition, characterized by patches of fine gray or white lines that intersect at irregular intervals in the peripheral retina, usually associated with numerous, round, ...
What are the hallmarks of hyperkeratosis?
Histological hallmarks include hyperkeratosis with follicular plugging of stratum corneum but thinning and flattening of stratum malpighii with hydropic degenerationof basal cells and lymphocytic infiltrate arranged along the dermal-epidermal junction, perivascular and periappendageal structure.1
What is a leiomyoma composed of?
On microscopic examination, showed leiomyomas composed of intersecting fascicles of closely packed cells with elongated nuclei and eosinophilic cytoplasm with secondary changes of hyalinization, ossification associated with hydropic degeneration[Fig 2, 3].
