A 54-year-old woman with obesity, type II diabetes mellitus, hyperlipidemia, and massive hepatomegaly was found to have severe steatosis and cirrhosis on liver biopsy. Complete evaluation led to the diagnosis of fatty cirrhosis associated with obesity and diabetic mellitus. She underwent four months of fasting with a protein-carbohydrate and vitamin-mineral liquid supplement to control her weight and metabolic abnormalities and to evaluate the effect of this diet on her liver disease. She lost 40 pounds to ideal body weight, normalized her serum glucose and lipids, and decreased total liver height by one third. Liver biopsy at the completion of her diet showed inactive cirrhosis and complete resolution of steatosis. Supplemented fasting with only modest weight loss can safely resolve fatty liver in obese diabetics with nonalcoholic steatosis and cirrhosis. Aggressive dietary approaches to achieve long-term weight loss deserve study in this subgroup of diabetics with unexplained chronic liver disease.

We report the clinical and pathologic features of five children wih a botyroid rhabdomyosarcoma of the biliary tract. There were three boys and two girls ranging in age from 11/2 to 51/2 years at diagnosis. Obstructive jaundice was the usual presenting sign, often with fever and hepatomegaly. Of four tumors involving the common bile ducts, two extended into porta hepatis and adjacent liver parenchyma; the fifth tumor arose in the wall of the cystic duct. Each had a typical botryoid (grape-like) configuration with a cambium layer of tumor cells beneath biliary epithelium. Rhabdomyoblasts were identified in all cases and confirmed by ultrastructure in one. Our data, along with review of other cases reported in the English literature, indicate a rather guarded prognosis. Although metastases have developed in 40% of cases, death was usually due to the effects of local invasion by tumor. Aggressive adjuvant therapy currently in use for childhood rhabdomyosarcomas may lessen the high mortality associated with this tumor.

Hepatocellular carcinoma (HCC) occurs more frequently in subsaharan Africa and the Orient than in other geographical regions, but remains an uncommon tumour of childhood. We review six children with HCC (mean age 13 years) treated by the paediatric oncology unit at Tygerberg Hospital in Cape Town over an 8-year period (1983 - 1990). Patients presented with epigastric and right upper quadrant discomfort and hepatomegaly. The hepatitis B serum antigen (HbsAg) was positive in three patients; serum alpha-fetoprotein (AFP) levels were markedly elevated in three (range 100 - 453,000 microg/l). Age and sex did not differ significantly and all patients initially had irresectable advanced-stage tumours. Morphologically, three were highly malignant adult-type pleomorphic HCCs, two were differentiated tumours, and one a fibrolamellar subtype. The mean 2-year survival was 33% and the 5-year survival 16.6%. The biological behaviour and response to treatment of the tumours varied. Whereas three patients had a poor response to therapy, two with poorly-differentiated tumours, negative HbsAg, and normal serum AFP levels responded to doxorubicin/cisplatinum chemotherapy. This facilitated radical surgical excision. One patient of this group has survived for more than 75 months following surgical resection and remains well. HCC remains an uncommon tumour of childhood with a high mortality. Aggressive chemotherapeutic regimes in combination with surgical resection may lead to improved survival in some cases. Prevention of hepatitis B remains a priority.

Aggressive natural killer-cell leukemia (ANKL) is a rare form of large granular lymphocyte leukemia, which is characterized by a systemic proliferation of NK cells. The clinical features of 22 ANKL cases were analyzed. Hepatomegaly (64%), splenomegaly (55%) and lymphadenopathy (41%) were also frequently observed. Leukemic cells were identified as CD1-, CD2+, surface CD3-, CD4-, CD5-, CD7+, CD8+/-, CD10-, CD11b+/-, CD13-, CD16+, CD19-, CD20-, CD25-, CD33(-), CD34-, CD38+, CD56+, CD122+, HLA-DR+ and TCR-. Two of the 16 cases examined for CD57 were positive and three of the seven cases examined for cytoplasmic CD3. Epstein-Barr virus was detected in the tumor cells of 11 of the 13 cases examined. No common cytogenetic abnormalities were identified and 6q anomaly was detected in only one. Three of 13 patients treated with chemotherapy containing anthracycline/anthraquinone attained complete remission, in contrast to none of the eight who were treated with regimens without anthracycline. Although the overall prognosis was poor with a median survival of 58 days, those who attained remission showed better prognosis (P=0.005). These findings suggest that ANKL is an entity of mature cytotoxic NK-cell neoplasms with distinct phenotype and disease presentations. Intensive treatment for ANKL may result in a better prognosis.

Aggressive natural killer (NK) cell leukemia (ANKL) is a rare form of leukemia with an aggressive clinical course. It commonly involves the peripheral blood, bone marrow, liver, and spleen but rarely involves the lungs. We report a 36 year-old woman who presented with pulmonary lesions we suspected to be interstitial lung disease on an imaging study. A lung biopsy showed extensive lymphoid infiltrate growing along pre-existing alveolar septa without destroying the alveolar spaces. Further workup revealed hepatomegaly, borderline splenomegaly, and multiple lymphadenopathies. Her laboratory tests showed leukocytosis, anemia, thrombocytopenia, abnormal liver enzymes, and elevated lactate dehydrogenase. A bone marrow (BM) aspirate smear revealed many intermediate to large lymphocytes with dispersed chromatin, basophilic cytoplasm, and some azurophilic granules. A BM biopsy showed hypercellularity with interstitial lymphoid infiltrate in a background of trilineage hematopoiesis and histiocytosis with hemophagocytosis. Immunohistochemical studies performed on both the lung and BM biopsies showed the neoplastic cells to be positive for CD2, CD3, CD7, CD56, granzyme B, phosphor-MAPK (pMAPK), EBER (Epstein-Barr Virus-encoded small RNA) by in situ hybridization; they were negative for CD4, CD5, CD8, CD30, LMP1, and phospho-STAT3 (pSTAT3). A flow cytometry analysis of the BM aspirate identified a population of atypical lymphocytes with the NK cell phenotype. Molecular studies were negative for T-cell receptor gene rearrangements, and the neoplastic cells displayed a complex karyotype. The patient responded initially to chemotherapy but died of multiorgan failure two months after the diagnosis. We present a case of ANKL mimicking interstitial lung disease with the activation of MAPK pathway.
