Liver lesions in an autopsy population

Area of Science:

• Pathology
• Hepatology
• Forensic Medicine

Background:

• Liver lesions are common findings in autopsies.
• The coronial system provides a unique dataset for studying liver pathology.
• Understanding the prevalence of various liver lesions is crucial for public health.

Purpose of the Study:

• To document the spectrum of liver lesions found in a large autopsy series.
• To identify the frequency of solitary liver lesions, including clinically silent ones.
• To assess the prevalence of specific lesions such as cirrhosis, adenomas, metastatic carcinoma, and hamartomas.

Main Methods:

• Retrospective examination of liver specimens from 1500 consecutive autopsies.
• Inclusion of cases from the southeast London coronial system.
• Categorization and documentation of all identified liver lesions.

Main Results:

• A wide range of liver lesions were identified across the 1500 autopsies.
• Approximately 5% of examined livers presented with a solitary lesion.
• Clinically non-evident lesions included cirrhosis, adenomas, and metastatic carcinoma; hamartomas were found to be relatively common.

Conclusions:

• Autopsy studies are vital for characterizing liver pathology in the general population.
• Solitary and clinically silent liver lesions are not uncommon and include significant diagnoses.
• Hamartomas represent a frequent finding in liver autopsy examinations.
