Primary hepatic lymphoma: a rare case report and literature review

Primary hepatic lymphoma (PHL) is a rare malignancy, which only occupies about 0.4% of all primary extranodal non-Hodgkin lymphomas (NHLs) and 0.016% of all NHLs. It includes B-cell lymphoma, T-cell lymphoma, and others. A seventy-one year old man first went to visit the doctor because of pneumonia and then he was diagnosed with PHL of diffuse large B-cell lymphoma with no virus hepatitis or other typical symptoms. PHL is a rare disease, which is very difficult to diagnose due to non-specific clinical manifestations and accessory examinations. This case may help clinicians to improve their understanding of this disease.
