Hepatic Angiosarcoma
Overview
Plain-Language Overview
Hepatic Angiosarcoma is a rare and aggressive cancer that starts in the blood vessels of the liver. It affects the liver, an important organ responsible for filtering toxins and producing vital proteins. This cancer grows quickly and can cause symptoms like abdominal pain, swelling, and unexplained weight loss. Because it involves the blood vessels, it can lead to bleeding inside the liver and spread to other parts of the body. Diagnosis is often challenging, and the disease usually progresses rapidly, impacting overall health severely.
Clinical Definition
Hepatic Angiosarcoma is a malignant tumor arising from the endothelial cells lining the hepatic blood vessels. It is characterized by aggressive, infiltrative growth and a high propensity for vascular invasion and metastasis. The pathogenesis often involves exposure to carcinogens such as vinyl chloride, arsenic, and thorotrast. Clinically, it presents with nonspecific symptoms including hepatomegaly, abdominal pain, and signs of liver failure. Histologically, it shows irregular, anastomosing vascular channels lined by atypical endothelial cells. The tumor is highly aggressive with poor prognosis due to late diagnosis and limited effective treatment options.
