In histo pathology, ballooning degeneration, formally ballooning degeneration of hepatocytes, is a form of liver parenchymal cell (i.e. hepatocyte) death. The name is derived from the fact that the cells undergoing this form of cell death increase in size ( balloon ).
Riedel's thyroiditis is characterized by a replacement of the normal thyroid parenchyma by a dense fibrosis that invades adjacent structures of the neck and extends beyond the thyroid capsule. [3] This makes the thyroid gland stone-hard (woody) and fixed to adjacent structures.
Thyroid disease is a medical condition that affects the function of the thyroid gland. The thyroid gland is located at the front of the neck and produces thyroid hormones [1] that travel through the blood to help regulate many other organs, meaning that it is an endocrine organ. These hormones normally act in the body to regulate energy use ...
Benign liver tumors generally develop on normal or fatty liver, are single or multiple (generally paucilocular), have distinct delineation, with increased echogenity (hemangiomas, benign focal nodular hyperplasia) or absent, with posterior acoustic enhancement effect (cysts), have distinct delineation (hydatid cyst), lack of vascularization or show a characteristic circulatory pattern ...
The increase in the risk of nerve injury can be due to the increased vascularity of the thyroid parenchyma and the development of links between the thyroid capsule and the surrounding tissues. Reportedly, a 1% incidence exists of permanent recurrent laryngeal nerve paralysis after complete thyroidectomy. [27]
Apoptosis of the liver of a mouse. Hepatocytes are the liver's primary parenchymal cells, forming 80% of the liver's mass and 60% of its cells. They are round in shape and contain a nucleus and organelles that contribute to metabolic and secretory functions. [5] Hepatocytes also play a pivotal role in liver inflammation. [6]
In histo pathology, feathery degeneration, formally feathery degeneration of hepatocytes, is a form of liver parenchymal cell (i.e. hepatocyte) death associated with cholestasis. [1] Cells undergoing this form of cell death have a flocculant appearing cytoplasm, [2] and are larger than normal hepatocytes.
Hypothyroidism (also called underactive thyroid, low thyroid or hypothyreosis) is a disorder of the endocrine system in which the thyroid gland does not produce enough thyroid hormones. [3] It can cause a number of symptoms, such as poor ability to tolerate cold , extreme fatigue, muscle aches , constipation , slow heart rate , depression , and ...
