Hepatic Diffuse Large B-cell Lymphoma: A Case Report and Review of Literature of Primary Liver Tumors

Liver tumors rank as the fourth most common cause of cancer. This case report highlights a 45-year-old female patient who presented persistent abdominal pain and no other symptoms. Initially, she was approached with a probable hepatitis of unknown origin, but her condition worsened rapidly. An endoscopic ultrasound was used to characterize the lesion, and a fine needle biopsy of the lesion was performed which revealed a diffuse large B-cell lymphoma that is CD20+ and Ki67+. Hepatic diffuse large B-cell lymphoma, as diagnosed in the patient, is a rare type of lymphoma that arises in the liver. The treatment usually involves chemotherapy, immunotherapy, and radiation therapy. However, the prognosis depends on the stage of the disease and the patient's overall health. This case reinforces the importance of considering hepatic diffuse large B-cell lymphoma in differential diagnosis for primary liver neoplasia.
