Extrahepatic biliary tract obstruction due to plasmacytoma

Area of Science:

• Hepatology
• Oncology
• Gastroenterology

Background:

• Multiple myeloma can infiltrate the liver, leading to hepatic dysfunction and elevated liver enzymes.
• Discrete plasmacytomas, unlike diffuse infiltration, rarely impact hepatobiliary function.

Observation:

• A patient presented with jaundice, indicating a potential hepatobiliary issue.
• The cause of jaundice was identified as an abdominal plasmacytoma.

Findings:

• The abdominal plasmacytoma led to extrahepatic biliary obstruction.
• This obstruction resulted in the patient's jaundice.

Implications:

• This case expands the understanding of how plasmacytomas can affect liver function.
• Highlights the importance of considering rare causes of biliary obstruction in oncology patients.
