Hepatic amyloidosis, though uncommon, can lead to severe liver disease. This study highlights two cases diagnosed via liver biopsy, emphasizing the importance of recognizing this condition in patients with related symptoms.

Area of Science:

Nephrology
Cardiology
Hepatology

Background:

Amyloidosis classification depends on deposition patterns and associated diseases.
Hepatic amyloidosis is often asymptomatic but can present with liver-specific symptoms.
Liver biopsy is crucial for diagnosing amyloidosis, especially when hepatic involvement is suspected.

Observation:

Two cases of amyloidosis diagnosed by liver biopsy are presented.
Case 1: Symptoms included jaundice and hepatomegaly, with echocardiogram showing hypertrophic cardiomyopathy; patient died of hepatic failure.
Case 2: Found in a patient with end-stage renal disease, exhibiting congestive heart failure, possibly indicating cardiac involvement.

Findings:

Both cases demonstrated diffuse perisinusoidal hepatic amyloid deposition.

The predominant intralobular deposition pattern suggests secondary amyloidosis in both patients.

Clinical presentation varied, ranging from severe liver failure to cardiac complications in end-stage renal disease.

Implications:

Highlights the clinical significance of hepatic amyloidosis, even when rare.
Underscores the potential for systemic involvement, including cardiac and renal systems.
Emphasizes the diagnostic value of liver biopsy for identifying hepatic amyloidosis and guiding patient management.
