Abstract
Primary hepatic lymphoma (PHL) is a rare malignancy whose pathogenesis is still unclear. Most PHL patients present with upper abdominal pain, upper abdominal distention or discomfort. Laboratory tests may reveal either a cholestatic or a cytolytic process, with elevated lactate dehydrogenase in most patients. Imaging tests often reveal an isolated lesion in the liver. The predominant histological type of PHL is B-cell lymphoma. At present, there are no standard diagnostic criteria for PHL. PHL is often misdiagnosed as many other liver diseases. Biopsy is usually performed to make a definite diagnosis. Treatment options for PHL include various modalities, and the prognosis of PHL is better than that of primary hepatic carcinoma.
