Summary
This study reports a rare case of hepatocellular carcinoma (HCC) with extensive peliosis. The findings highlight a unique presentation of liver cancer with dilated blood-filled sinusoids within the tumor.
Area of Science:
- Hepatobiliary Medicine
- Oncology
- Pathology
Background:
- Peliosis hepatis is a rare vascular liver lesion characterized by blood-filled cavities.
- Hepatocellular carcinoma (HCC) rarely presents with significant peliosis.
- Understanding rare HCC presentations is crucial for diagnosis and management.
Observation:
- A case of an 8-cm liver lesion in a 73-year-old man.
- Imaging revealed a hyperechoic lesion with specific enhancement patterns and a 'cotton-wool' sign on arteriography.
- Fine-needle aspiration biopsy confirmed hepatocellular carcinoma.
Findings:
- Histological examination of the resected tumor showed well-differentiated HCC.
- The HCC nodule exhibited extensive dilated sinusoid-like structures, indicative of peliosis.
- This represents a rare confluence of hepatocellular carcinoma and peliosis hepatis within a single tumor nodule.
Implications:
- This case expands the known spectrum of hepatocellular carcinoma presentations.
- Recognition of peliosis-like changes in HCC is important for accurate pathological diagnosis.
- Further research may elucidate the mechanisms behind this combined pathology.

01:24Cirrhosis II: Pathophysiology
Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...
01:23Cirrhosis I: Introduction
Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...
01:24Liver Regeneration
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are large...
