Primary Hepatic Lymphoma: A Rare Form of Diffuse Large B-Cell Lymphoma of the Liver.

BACKGROUND

Primary hepatic lymphoma is a rare, malignant lymphoma of the liver unlike the predominant lymph nodal or splenic involvement associated with other types of lymphoma. It is commonly associated with nonspecific symptoms and usually detected incidentally on imaging examination.

CASE PRESENTATION: An 84-year-old man was evaluated for upper back pain. Chest computed tomography showed multiple large lesions in the liver, leading to the diagnosis of primary diffuse large B-cell lymphoma of the liver. Within 2 weeks of detecting his liver mass, the patient developed hypercalcemia and hyperuricemia that led to rapid deterioration and admission for treatment. Further diagnostic testing was performed, and he was initiated on appropriate chemotherapy.

CONCLUSIONS

Primary hepatic lymphoma, a form of diffuse large B-cell lymphoma of the liver is a rare disease without specific clinical manifestations, biochemical indicators, or radiologic features except for space-occupying liver lesions. However, patients' conditions can deteriorate rapidly at an advanced stage as demonstrated in this case, which highlights the importance of a high level of suspicion for early diagnosis and treatment.
