GI21 Flashcards
Hepatocellular Carcinoma/Hepatoma:
- General
Most common 1˚ malignant tumor of liver in adults
Hepatocellular Carcinoma/Hepatoma:
- increased risk associations
- Hepatitis B & C
- WIlson’s disease
- Hemochromatosis
- a1-antitrypsin deficiency
- Alcoholic cirrhosis
- Carcinogens (i.e., Aflatoxins from Aspergillus)
Hepatocellular Carcinoma/Hepatoma:
- Findings
- Jaundice
- Tender hepatomegaly
- Ascites
- Polycythemia
- Hypoglycemia
- INcreased Prothrombin Time (PTT) d/t DEcrease in Vit. K dependent clotting factors
- INcreased a-fetoprotein
Hepatocellular Carcinoma/Hepatoma:
- May lead to
Budd-Chiari syndrome
Hepatocellular Carcinoma/Hepatoma:
- Metastasis (spread)
Hematogenous dissemination
Carvernous hemangioma.
- Common
- Benign
- 30-50 y.o
- Biopsy CONTRAINDICATED (risk of hemorrhage)
Hepatic adenoma.
- Benign
- Oral contraceptives
- Steroid use
- May regress spontaneously
Angiosarcoma.
- Malignant tumor of Endothelial origin
- Exposure to - Arsenic or PVC
Nutmeg Liver.
- Backup of blood into liver
- Causes: Right-sided HF, Budd-Chiari syndrome
- Chronic: Centrilobular congestion and necrosis
- Cardiac cirrhosis
Budd-Chiari syndrome.
- Occlusion of IVC or hepatic veins
- Centrilobular congestion and necrosis
- Leads to congestive liver disease (hepatomegaly, ascites, abdominal pain, eventual liver failure)
- Absence of JVD
- Associated with: Hypercoagulable state, Polycythemia vera, Pregnancy, Hepatocellular carcinoma
a1-antitrypsin deficiency - Liver.
1-Misfolded gene product protein aggreates in hepatocellular ER
2-Cirrhosis w/ PAS-positive globules in liver
*Codominant trait
a1-antitrypsin deficiency - Lung.
1-Lack of functioning enzyme
2-DEcrease elastic tissue
3-Panacinar emphysema
*Codominant trait
