Аннотация
RATIONALE: Primary hepatic lymphoma (PHL) is an extremely rare manifestation of extranodal non-Hodgkin lymphoma. There were few cases about PHL in recent years, while cases using positron emission tomography (PET) modalities for both diagnosis and follow-up were even rare.
PATIENT CONCERNS: A 29-year-old man complaining of dull epigastric pain for 2 weeks.
DIAGNOSIS: The features of liver biopsy and immunohistochemistry were consistent with diffuse large B cell lymphoma. Since there were no other foci of lymphoma on the F-fluoro-2-deoxy-D-glucose (F-FDG) PET/computed tomography (CT) images, the patient was further diagnosed with PHL.
INTERVENTIONS: Since the lesions were mainly confined to the right lobe of liver, partial hepatectomy and radiofrequency ablation were performed. Subsequently, 6 cycles of rituximab, cyclophosphamide, adriamycin, vincristine, dexamethasone regimen were performed.
OUTCOMES: The patient recovered well postoperatively and was discharged 1 week after surgery. Fortunately, the follow-up F-FDG PET/CT scan 36 months later revealed no abnormal FDG uptake, indicating the absence of relapse.
LESSONS: As the superiority in excluding other organ involvement, F-FDG PET/CT should be considered as the preferable imaging modality for the diagnosis and follow-up of PHL. Besides chemotherapy, surgical resection should be considered initially. If radical R0 resection could not be done, partial hepatectomy with radiofrequency ablation may also offer an appropriate alternative treatment.
