title: Primary hepatic non-Hodgkin's lymphoma in children: a case report and review of the literature.
abstract: Non-Hodgkin's lymphomas presenting exclusively in the liver are rather uncommon in adults and extremely rare in children. We describe a six-year-old white boy with jaundice, abdominal pain, and weight loss of two weeks duration. Physical examination disclosed asthenia, jaundice, abdominal swelling, large hepatomegaly, and ascitis. Aminotransferases bilirubin, and alkaline phosphatase were significantly elevated. Bone marrow aspiration, cerebrospinal fluid, chest x-ray, renal function tests, and uric acid were normal. Abdominal ultrasound showed liver enlargement with irregular regular borders, many parenchymal nodules in both liver lobes, a large hypoechogenic mass in the inferior segment of the liver, normal biliary ducts and two pancreatic nodules resembling those in the liver. Liver needle biopsy disclosed diffuse lymphomatous infiltration. Blast cells were positive for leukocyte common antigen (CD 45). Immunohistochemistry study for T or B cell lineage differentiation was not done. The child showed an excellent response to chemotherapy based on the BFM-83 protocol for B cell non-Hodgkin's lymphomas. The patient had his therapy discontinued in June 1995 and remains in first complete remission as of May 20th, 1996.
