Cirrhosis is a complication of liver disease which involves loss of liver cells and irreversible scarring of the liver. Typically, the disease comes on slowly over months or years. Early on, there are often no symptoms.  As the disease worsens, a person may become tired, weak, itchy, have swelling in the lower legs, develop yellow skin, bruise easily, have fluid build up in the abdomen, or develop spider-like blood vessels on the skin. Cirrhosis is most commonly caused by alcohol, hepatitis B, hepatitis C, and non-alcoholic fatty liver disease. Non-alcoholic fatty liver disease is due to a number of reasons, including being overweight, diabetes, high blood fats, and high blood pressure.  Cirrhosis is characterized by the replacement of normal liver tissue by scar tissue. These changes lead to loss of liver function. Diagnosis is based on blood testing, medical imaging, and liver biopsy.  Image illustrates hepatic steatosis and chronic hepatitis.  Trichrome stain
Light micrograph of an unstained iris showing the localization of pigment cells. The melanin pigment is concentrated in the back surface of the iris stroma, near the pigment epithelium (right). Between both, there is a clear band that corresponds to the iris dilator muscle. The anterior surface shows a lower concentration of pigment.
