1/2279. Intact PTH-producing hepatocellular carcinoma treated by transcatheter arterial embolization.

    We report a case of hepatocellular carcinoma with hypercalcemia. There was no evidence of bone metastasis or increase in parathyroid hormone-related protein. The serum level of intact parathyroid hormone (intact PTH) was very high, and the results of the hepatic venous sampling suggested that the tumor produced intact PTH. Transcatheter arterial chemoembolization effectively controlled the humoral hypercalcemia.

2/2279. Premalignant lesions and hepatocellular carcinoma in a non-cirrhotic alcoholic patient with iron overload and normal transferrin saturation.

    A 66-year-old white man had a hepatic resection for a 6-cm well-differentiated hepatocellular carcinoma which had developed in a non-cirrhotic liver. The only risk factors found were heavy drinking, smoking and heterozygosity for the C282Y mutation of the HFE gene. The liver was mildly fibrotic and overloaded with iron. It also contained numerous iron-free hepatocellular lesions from <1 to 10 mm, suggesting a premalignant change. These lesions were of three types: (i) iron-free foci, (ii) hyperplastic nodules and (iii) dysplastic nodules with severe dysplasia or even foci of well-differentiated grade I hepatocellular carcinoma. This observation suggests the possibility of malignant transformation of the liver in the newly-described syndrome of iron overload and normal transferrin saturation. It also illustrates the multistep process of carcinogenesis in the non-cirrhotic liver.

3/2279. Primary yolk sac tumour of the liver in adulthood.

    Primary yolk sac tumour of the liver is exceedingly rare. A 28 year old woman presented with a cystic liver mass and a markedly raised serum alpha-fetoprotein concentration. She underwent a partial hepatectomy for a suspected hepatocellular carcinoma but histological examination of the tumour revealed the classical morphological and immunohistochemical features of a yolk sac tumour. There was no evidence of an extrahepatic primary source. review of this case, together with the six previously reported adult cases of primary yolk sac tumours of the liver, revealed several features of the tumour that may aid differentiation from hepatocellular carcinoma, with potential therapeutic implications.

4/2279. Central line sepsis in a child due to a previously unidentified mycobacterium.

    A rapidly growing mycobacterium similar to strains in the present mycobacterium fortuitum complex (M. fortuitum, M. peregrinum, and M. fortuitum third biovariant complex [sorbitol positive and sorbitol negative]) was isolated from a surgically placed central venous catheter tip and three cultures of blood from a 2-year-old child diagnosed with metastatic hepatoblastoma. The organism's unique phenotypic profile and ribotype patterns differed from those of the type and reference strains of the M. fortuitum complex and indicate that this organism may represent a new pathogenic taxon.

5/2279. renal artery rupture secondary to pretransplantation Candida contamination of the graft in two different recipients.

    Infected graft transplantation is an unwelcome complication that may lead to serious consequences in the immunosuppressed host. It can be caused by infection of the donor or by contamination of the organ during harvest, preservation and handling, or at transplantation. With current donor evaluation protocols, the risk of transmitting infections by exogenous contaminated grafts seems to be more frequent than true donor-transmitted infections. Nevertheless, although rare and usually free of clinically significant sequelae, if contamination is by some virulent organisms such as staphylococcus aureus, gram-negative bacilli, or fungi, severe complications may occur. We report the clinical outcome of liver, heart, and kidney recipients from a single donor. Both renal allografts had to be removed because of renal artery rupture secondary to candida albicans infection. Careful donor evaluation before transplantation, unusually early presentation of mycosis leading to anastomotic renal artery disruption, the histopathologic findings of the grafts, and the absence of Candida infection in the liver and heart recipients make us believe that exogenous contamination of the grafts occurred during donor procedure, kidney processing, or at transplantation. In summary, because infected grafts can lead to serious complications, besides careful donor screening, it is important to achieve early recognition of contaminated organs by culturing the perfusate to start specific antibiotic or antifungal therapy after transplantation if necessary and avoid the rare but, in this case, fatal consequences of these infections.

6/2279. Metastasis of hepatocellular carcinoma to the right colon manifested by gastrointestinal bleeding.

    An 82-year-old black woman with a history of hepatocellular carcinoma presented with gastrointestinal bleeding. barium enema and fibrocolonoscopy revealed a 4-cm polypoid mass at the level of the ascending colon with evidence of active bleeding. Biopsies of the lesion proved it to be metastatic hepatocellular carcinoma. Exploratory laparotomy revealed no further dissemination of the tumor, and the patient underwent an ileocolectomy. The serosal side of the colonic lesion was free from tumor, and there was no peritoneal implantation, direct extension, or lymph node involvement. This case represents an extremely rare presentation of metastatic hepatocellular carcinoma.

7/2279. Effects of diabetes mellitus on patients with acute intermittent porphyria.

    OBJECTIVES: To study the effects of diabetes mellitus in patients with acute intermittent porphyria (AIP). Haeme deficiency in the liver of AIP patients stimulates an increase in ALA-synthase which triggers an escalating metabolic chain reaction, leading to an increase in the porphyrin content. This reaction can be reduced by treating AIP patients with haeme arginate or with glucose. DESIGN: A population-based study of all patients > 18 years of age having dna-verified AIP (n = 328) living in the two most northerly counties of sweden (Norrbotten and Vasterbotten, with 550,000 inhabitants) of whom 16 had type 2 diabetes. prevalence of diabetes was studied retrospectively in 26 AIP patients with hepatocellular carcinoma (HCC). RESULTS: None of the patients showed symptoms of AIP after the onset of their diabetes. Three patients had had recurrent, severe attacks for many years but when their diabetes became manifest, their urinary ALA and PBG levels decreased and the AIP symptoms resolved, to the relief of the patients. Amongst the 26 AIP patients with HCC, only one with signs of diabetes was identified (impaired glucose tolerance test). CONCLUSIONS: This study raises the possibility that diabetes mellitus may be beneficial for patients with severe AIP.

8/2279. Is the presence of surgically treatable coronary artery disease a contraindication to liver transplantation?

    Advanced coronary artery disease has been traditionally considered an absolute contraindication to orthotopic liver transplantation where chronic liver failure significantly increases the surgical risk for coronary artery bypass grafting. Performing a simultaneous coronary artery bypass grafting and liver transplant is a theoretically attractive strategy in liver transplant candidates with coronary artery disease in need of revascularization. In the present article, we report a successful simultaneous coronary artery bypass grafting and orthotopic liver transplant with 1-yr post-operative follow-up and we discuss the rationale for this approach. In selected cases, the presence of advanced coronary artery disease should not be considered an absolute contraindication to liver transplantation.

9/2279. Combined hepatocellular-cholangiocarcinoma. Diagnostic challenge in hepatic fine needle aspiration biopsy.

    OBJECTIVE: To study the cytohistologic features of combined hepatocellular-cholangiocarcinoma (CHCC-CC) in fine needle aspiration biopsy (FNAB) material. STUDY DESIGN: Six hepatic FNAB cases with cell blocks (five) and hepatic resections (two) were analyzed cytohistologically and immunohistochemically. RESULTS: The six cases were diagnosed as CHCC-CC based on clinicopathologic correlation. Unequivocal hepatocellular carcinoma (HCC) cells corresponding to Edmondson and Steiner's grade 3 lesions were identified in the FNAB in three instances. adenocarcinoma, represented by cohesive columnar cells with ovoid, basal nuclei displaying nuclear palisading, acini and/or papillary structures with variable intracytoplasmic intraacinar or brush border mucin production, was identified in all cases. Intermediate cells with hybrid/polymorphic cytologic features straddling malignant hepatocytes and glandular cells were identified in five instances. Tissue alpha-fetoprotein was negative. There was brush border and/or diffuse cytoplasmic p-carcinoembryonic antigen immunoreactivity in the glandular elements. CONCLUSION: FNAB diagnosis of CHCC-CC is possible if the clinical, cytohistologic and immunohistochemical findings support the presence of HCC and adenocarcinoma. Intermediate cells pose a great challenge to recognize and define: they tend to lose the classic cytologic features of malignant hepatocytes and acquire glandular characteristics. At the very least, there should be a high index of suspicion. These cases underscore the necessity for clinicopathologic correlation in enhancing the precision of FNAB diagnoses.

10/2279. Hepatocellular carcinoma with fibrolamellar pattern in a patient with autoimmune cholangitis.

    A 75-year-old woman with a 15-year history of autoimmune cholangitis underwent orthotopic liver transplantation because of progressive liver decompensation. A clinically unsuspected hepatocellular carcinoma was found. A portion of the tumor showed fibrolamellar differentiation. Hepatocellular carcinoma, either with the usual pattern or with a fibrolamellar pattern, is rare in the setting of primary biliary cirrhosis, but has been seen in the setting of autoimmune hepatitis. Autoimmune cholangitis is a relatively recently recognized form of autoimmune liver disease whose association with hepatocellular carcinoma has yet to be determined.
