Abstract

Keywords: Necrosis; Hepatocytes.

Introduction

Necrosis, also referred to as cell death, is a process in which feasible cells become nonviable, resulting in termination of the cell contents. Under physiological conditions it is a well-regulated process that leads to renewal of individual effete cells. However, under pathological conditions, necrosis is often the end outcome of various forms of tissue injury. Apoptosis (Individual Cell Necrosis).

Apoptosis is a term used to report death of individual cells. Under physiological conditions it is a well-synchronized, slow process that leads to cell renewal and tissue rearrangement. In pathological conditions, the process is less controlled and often more rapidly escalating

Spotty and Focal Necrosis. Spotty necrosis is a denomination used to describe necrosis of minute clusters of hepatocytes, usually in relation with lymphocytes (Fig. 2).

Necrosis involving larger groups of hepatocytes within a lobule may be mentioned to as focal necrosis. These terms describe a continuum of lobular injury and are often used to describe lobular changes in hepatitis

Viral hepatitis can be related with all the patterns of necrosis described earlier, with mild cases showing apoptosis, spotty necrosis, and lenient piecemeal necrosis, and more severe cases showing centrilobular, bridging, and convergent necrosis

After transplantation, necrosis in the allograft may result from conservation/reperfusion injury, acute nonfunction, rejection, ischemia, and hepatitis, with the scope and pattern of necrosis depending on the extremity of the underlying cause

Ballooning (feathery) degeneration

Term used to express swelling and rounding up of injured hepatocytes in the setting of marked hepatitis or cholestasis; considered a sign of development to hepatocyte apoptosis and cell death also called feathery deterioration in the setting of chronic cholestasis

Pathophysiologically, ballooning is a result of critical cell injury, depletion of adenosine triphosphate (ATP) and rise in intracellular calcium, directing to loss of plasma membrane volume control and disruption of the hepatocyte intervening filament network

Bridging necrosis

Necrosis is the chief mode of death with onset of irreversible injury, in states of extreme ATP exhaustion (as during ischemia or hypoxic cell injury), toxic injury (as from acetaminophen) and oxidative stress with reactive oxygen species development

Pathophysiologically, necrosis is escorted by extensive damage to all cellular membranes, swelling of lysosomes, vacuolization of mitochondria and substantial catabolism of cellular membranes, proteins, ATP and nucleic acid, with karyolitic and issue of cellular contents
