  2. Liver cancer - Wikipedia

    en.wikipedia.org/wiki/Liver_cancer

    Liver tumor types by relative incidence in adults in the United States (liver cancers in dark red color). [14] The most frequent liver cancer, accounting for approximately 75% of all primary liver cancers, is hepatocellular carcinoma (HCC). [15] HCC is a cancer formed by liver cells, known as hepatocytes, that become malignant. In terms of ...

    en.wikipedia.org/wiki/Fibrolamellar_hepato...

    The usual markers for liver disease – aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase – are often normal or only slightly elevated. FLC often does not produce alpha fetoprotein (AFP), a widely used marker for conventional hepatocellular carcinoma.

  4. Liver tumor - Wikipedia

    en.wikipedia.org/wiki/Liver_tumor

    Liver tumors (also known as hepatic tumors) are abnormal growth of liver cells on or in the liver. Several distinct types of tumors can develop in the liver because the liver is made up of various cell types. [1] Liver tumors can be classified as benign (non-cancerous) or malignant (cancerous) growths.

  5. Hepatocellular carcinoma - Wikipedia

    en.wikipedia.org/wiki/Hepatocellular_carcinoma

    On ultrasound, HCC often appears as a small hypoechoic lesion with poorly defined margins and coarse, irregular internal echoes. When the tumor grows, it can sometimes appear heterogeneous with fibrosis, fatty change, and calcifications. This heterogeneity can look similar to cirrhosis and the surrounding liver parenchyma.

  6. Calcification - Wikipedia

    en.wikipedia.org/wiki/Calcification

    In a number of breast pathologies, calcium is often deposited at sites of cell death or in association secretions or hyalinized stroma, resulting in pathologic calcification. For example, small, irregular, linear calcifications may be seen, via mammography, in a ductal carcinoma-in-situ to produce visible radio-opacities. [10]

  7. Ultrasonography of liver tumors - Wikipedia

    en.wikipedia.org/wiki/Ultrasonography_of_liver...

    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 ...

  8. Microcalcification - Wikipedia

    en.wikipedia.org/wiki/Microcalcification

    Mammogram microcalcifications in ductal carcinoma in situ. Microcalcifications are tiny deposits of calcium salts that are too small to be felt but can be detected by imaging. [1] They can be scattered throughout the mammary gland, or occur in clusters. Microcalcifications can be an early sign of breast cancer. Based on morphology, it is ...

  9. Cavernous liver hemangioma - Wikipedia

    en.wikipedia.org/wiki/Cavernous_liver_hemangioma

    A cavernous liver hemangioma or hepatic hemangioma is a benign tumor of the liver composed of large vascular spaces lined by monolayer hepatic endothelial cells. It is the most common benign liver tumour, and is usually asymptomatic and diagnosed incidentally on radiological imaging or during laparotomy for other intra-abdominal issues.
