| Abstract: | Background: Primary hepatic extranodal marginal zone lymphoma of mucosa-associated type (MALT) is an extremely rare liver neoplasm. The lesions are often misdiagnosed for the most common primary hepatic malignancy, such as hepatocellular carcinoma and cholangiocarcinoma. As the diagnosis is most often made after the resection, there are still no clear guidelines for the optimal treatment of these patients. Case Presentation: A 30-year-old male patient with known primary sclerosing cholangitis (PSC) was treated at the Department of Abdominal Surgery Ljubljana due to a mass in the right liver, believed to be an intrahepatic cholangiocarcinoma. Due to the extent of the disease, extended right hepatectomy with the resection of the hepatocholedochus, lymphadenectomy, and hepaticojejunal anastomosis were performed. After the surgery, the patient developed a small-for-size syndrome and therefore necessitated a liver transplantation (LT) that was afterwards successfully performed. Discussion: This case highlights the diagnostic challenges of differentiating primary hepatic MALT lymphoma from cholangiocarcinoma on imaging, especially in patients with underlying liver disease. Preoperative confirmation of the malignant disease could potentially change treatment course in our patient. Therefore, a serious surgical complication with development of small-for-size syndrome after major hepatectomy could potentially be prevented. Regarding the underlying liver disease, the patient could probably be a candidate for LT with the bridging chemotherapy. Conclusions: Primary hepatic MALT lymphoma is an extremely rare liver lesion but remains a valid option in a differential diagnosis of liver lesions in patients with chronic viral infection or autoimmune disease, especially in settings of cirrhosis. Moreover, a high level of suspicion must be raised in young patients with solitary liver mass and autoimmune liver disease. Surgical resection is the best way to achieve elimination of the disease. |
