Abstract
Familial adenomatous polyposis (FAP) due to APC mutation is associated with an increased risk of hepatoblastoma. All cases of hepatoblastoma in patients with FAP reported in the literature were reviewed. One hundred and nine patients were identified. Thirty-five patients (of 49 with data) were diagnosed with hepatoblastoma prior to a later diagnosis of FAP (often in association with advanced colorectal carcinoma), emphasizing a need to identify patients earlier with germline APC mutations for early colorectal carcinoma screening. Hepatoblastoma may present at birth, and screening for hepatoblastoma in infancy in families with FAP prior to APC mutation testing results may be warranted.

Abstract
Familial adenomatous polyposis is an inherited disorder characterized by the development of hundreds of colorectal adenomas during adolescence, which in many cases will transform into colorectal cancer by the fourth decade of life, along with the development of various malignant tumors including hepatoblastoma. We report on a female patient with a de novo interstitial deletion of 5q21.3-q23.3, encompassing the APC gene, associated with adenomatous polyposis and early colorectal cancer, hepatoblastoma, epidermoid cysts, mental retardation, several mild dysmorphic signs and lower limb venous thrombosis.

Abstract
Background/Aims Desmoid tumors (DTs) are rare, locally invasive neoplasms that may affect 10-25% of familial adenomatous polyposis (FAP) patients. Our aim was to evaluate incidence and clinical presentation among our patients, the potential impact on FAP outcome and to discuss treatment. Materials and methods Charts from 133 FAP (1977-2013) were reviewed. Patients with DTs were separated to retrieve demographic, clinical and management data. Follow-up was focused on disease evolution causing complications or death. Results 19 (14.3%) DTs were diagnosed, either after previous trauma (16) or during FAP surgery (3). This group comprised 8 men (42.1%) and 11 women (57.9%) with an average age of 32.9 years. Intervals from surgical trauma to DTs ranged from 7 to 60 months. ECMs were detected in 12 (63.1%) patients. DTs were located in the abdominal wall (8), abdominal cavity (8), abdominal wall and cavity (2) and left arm (1). Five patients (26.3%) referred family history of DTs. Patients presented severe complications such as small bowel obstruction (4) and hydronephrosis (2), being directly responsible for death in three patients. Conclusions (1) DTs developed in 14.3% of FAP, mostly after surgical trauma; (2) 30% caused severe morbidity; (3) identification of clinical risk factors may help surgeons to develop screening and therapeutic decisions.

Abstract
Hepatocellular adenoma (HCA) is a benign liver tumor that most frequently occurs in young women using oral contraceptives. We report a rare case of HCA in a 29 years old female with familial adenomatous polyposis (FAP). The first proband was her sister, who underwent a total colectomy and was genetically diagnosed as FAP. A tumor, 3.0 cm in diameter, was detected in the right lobe of the liver during a screening study for FAP. A colonoscopy and gastroendoscopy revealed numerous adenomatous polyps without carcinoma. The patient underwent a total colectomy and ileo-anal anastomosis and hepatic posterior sectoriectomy. The pathological findings of the liver tumor were compatible with HCA. The resected specimen of the colon revealed multiple colonic adenomatous polyps. Examination of genetic alteration revealed a germ-line mutation of the adenomatous polyposis coli (APC) gene. Inactivation of the second APC allele was not found. Other genetic alterations in the hepatocyte nuclear factor 1 alpha and β-catenin gene, which are reported to be associated with HCA, were not detected. Although FAP is reported to be complicated with various neoplasias in extracolic organs, only six cases of HCA associated with FAP, including the present case, have been reported. Additional reports will establish the precise mechanisms of HCA development in FAP patients.

Abstract
Hepatocellular adenoma (HA) is a benign liver tumor most frequently occurring in young women using oral contraceptives. We report a rare case of HA in a 27-year-old male patient with familial adenomatous polyposis (FAP). The patient underwent a total colectomy and ileo-rectal anastomosis for FAP in 2003. A preoperative computed tomography scan of the abdomen disclosed a tumor in the left-lobe of the liver, 5.8 cm in diameter. Pathologic examination of a needle biopsy disclosed HA, but he had never used anabolic steroids or other known inducers of HA. The size of the liver mass gradually increased to 8.5 cm during a follow-up period of 38 months, and a left hepatectomy was performed in 2006. Pathology of the resected specimen confirmed the diagnosis of HA. Although FAP is known to be complicated with neoplasia in various extracolonic organs, only five reported cases of HA have developed in patients with FAP, including this case. This is the first report of HA to develop in a male FAP patient.

Abstract
This article presents a case study of a patient who was treated for 5 years from the time of diagnosis until his death. The patient was diagnosed with familial polyposis at the age of 35 due to a family history of the same. He suffered from low body image and showed a poor response to treatment, especially regarding nutrition. The period of time related to the presentation of symptoms and the patient's subsequent deterioration was characterized by attempts on the part of nursing staff to improve the patient's quality of life. Treatment of multiple fistulae was employed, while keeping the skin intact, along with the creative development of a unique bandaging method. This article describes the course of the patient's disease and specifies his problems and their solutions. It is hoped that presentation of this case will benefit caregiving staff in dealing with similar cases.

Abstract
OBJECTIVES Germline mutation in adenomatous polyposis coli (APC) is detected in up to 80% of familial adenomatous polyposis (FAP) patients worldwide. In this study, we evaluated clinical features and APC mutations of Singapore FAP patients and contrasted genotype-phenotype correlation with Caucasians from other regions of the world and between FAP patients with and without detectable APC mutations. METHODS We screened 242 members from 57 unrelated FAP families using a combination of cDNA protein truncation test, multiplex ligation-dependent probe amplification, and differential expression techniques. RESULTS APC germline mutations were detected in 50 families. In contrast to Caucasians, fundic gland polyposis in Singapore patients was associated with APC mutations throughout the coding region and osteomas were also not confined to codon 767-1573. There was also no FAP-associated hepatoblastoma or medullablastoma. APC mutation-negative patients from four families with mixed (adenomatous/hyperplastic/atypical juvenile) polyps were subsequently reclassified as hereditary mixed polyposis syndrome (HMPS) patients. APC mutation-negative patients with classical adenomatous polyposis were negative for MYH, beta-catenin, and Axin 1 mutations. These patients had a significantly older age at diagnosis (P < 0.001) and more colorectal cancers (P= 0.017) than patients with APC mutations. CONCLUSIONS We achieved a 94% (50/53) APC mutation detection rate via a combination of techniques, suggesting that the current detection rate is probably not exhaustive. Singapore patients have some features similar to and other features distinct from Caucasians. Furthermore, APC mutation-negative patients have accelerated cancer progression that merits closer surveillance.

Abstract
We report a case of a 23-year-old Turcot female patient who was first diagnosed as having a pinealoblastoma. Thyroid papillary carcinoma was diagnosed a few months later, and multiple colonic polyps were detected three years after that. A genetic workup revealed an APC gene mutation in her family. Long-term survival (i.e., >5 years) of pinealoblastoma is considered to be 20 percent. A review of 25 documented Turcot cases determined that the average age at death is 20.3 years, raising the difficult question of whether she should undergo restorative proctocolectomy. Restorative proctocolectomy may itself cause major morbidity but is currently the only way to prevent colon cancer.

Abstract
Within the context of a national population-based case-control study--the United Kingdom Childhood Cancer Study (UKCCS)--we aimed to explore relationships between perinatal and maternal factors and childhood hepatic tumours, for participants with data available from medical records. 26/28 children with hepatic tumours (22/24 hepatoblastomas, 4/4 hepatocellular carcinomas (HCC)) and 4753 age- and sex-matched controls were included. Polyhydramnios was associated with 0.9% of control pregnancies and 13.6% of case pregnancies (Odds Ratio (OR)=28.64, 95% Confidence Interval (CI)=6.94-118.21, P<0.0001); eclampsia or severe pre-eclampsia complicated the pregnancies of 16.7% of mothers whose children developed hepatoblastoma compared with 0.5% of control pregnancies (OR=52.50, 95% CI=10.75-257.05, P<0.0001). Three children with hepatoblastoma weighed <1500 g at birth, two of whom weighed <1000 g (OR for birthweight <1500 g=69.00, 95% CI=11.98-397.17, P<0.0001). Of children with hepatoblastoma, 50% (11/22) had records of congenital anomalies, as did two of their mothers. Three mothers of children with hepatoblastoma had diagnoses of cancer--two of papillary carcinoma of the thyroid and one of acute lymphoblastic leukaemia (ALL). Paediatricians and others should be alert to the possibility of familial or genetic syndromes in children with hepatoblastomas. Potential links between maternal pre-eclampsia, low birthweight and subsequent malignancy merit further investigation. Hepatoblastoma is an extremely rare childhood tumour, but understanding the mechanism(s) underlying severe pre-eclampsia and eclampsia may also shed light on factors that contribute to the development of hepatoblastoma.

Abstract
Patients with familial adenomatous polyposis coli (FAP) carry heterozygous mutations of the APC gene. At a young age, these patients develop multiple colorectal adenomas that consistently display a second somatic mutation in the remaining APC wild-type allele. Inactivation of APC leads to impaired degradation of beta-catenin, thereby promoting continuous cell-cycle progression. The role of APC inactivation in rare extracolonic tumors of FAP patients has not been characterized sufficiently. Among tissue specimen from 174 patients with known APC germ-line mutations, we identified 8 tumors infrequently seen in FAP. To investigate the pathogenic role of APC pathway deregulation in these lesions, they were analyzed for second-hit somatic mutations in the mutational cluster region of the APC gene. Immunohistochemistry was performed to compare the expression pattern of beta-catenin to the mutational status of the APC gene. Exon 3 of the beta-catenin gene (CTNNB1) was analyzed for activating mutations to investigate alternative mechanisms of elevated beta-catenin concentration. Although CTNNB1 mutations were not observed, second somatic APC mutations were found in 4 of the 8 tumors: a uterine adenocarcinoma, a hepatocellular adenoma, an adrenocortical adenoma, and an epidermal cyst. These tumors showed an elevated concentration of beta-catenin. No APC mutations were seen in focal nodular hyperplasia of the liver, angiofibrolipoma, and seborrheic wart. This is the first study reporting second somatic APC mutations in FAP-associated uterine adenocarcinoma and epidermal cysts. Furthermore, our data strengthen a role for impaired APC function in the pathogenesis of adrenal and hepatic neoplasms in FAP patients.

Abstract
The cloning of two major breast cancer susceptibility genes, BRCA1 and BRCA2, in 1994 and 1995 and the subsequent development of commercial genetic testing has brought hereditary cancer genetics into the public eye. In addition to DNA-based genetic testing, new strategies and treatments have been developed to provide accurate assessment of cancer risk and to reduce the chances of cancer developing in the future. This increasing scientific and public attention has prompted some cancer patients and their families to find out whether they "have the cancer gene" and has placed more responsibility on primary care clinicians to identify people who should be referred for specialized services of hereditary cancer genetics.

Abstract
Recent findings have increased our understanding of the molecular mechanisms involved in the pathogenesis of hepatoblastoma and their relationship to the molecular pathology of familial adenomatous polyposis (FAP). Here, we describe hepatoblastoma in siblings who share a gene mutation for FAP inherited from their father. This observation confirms the link between these diseases and has implications for future molecular research. We also raise the question; should other members of 'at-risk' families be screened following a new diagnosis of either hepatoblastoma or FAP?

Abstract
The Wnt signaling pathway has long been known to direct growth and patterning during embryonic development. Recent evidence also implicates this pathway in the development of childhood tumors of the liver, the kidney, the brain, and the pancreas. Here, we review the current evidence on how constitutive activation of the Wnt signaling pathway may occur in hepato-, nephro-, medullo- and pancreatoblastomas. With particular emphasis the mutational activation of CTNNB1, an emerging major oncogene in solid childhood tumors, is discussed.
