Abstract
Gardner syndrome (GS) is a specific form of familial adenomatous polyposis (FAP), which manifests as colorectal polyps, multiple osteomas and soft tissue tumors, and in the oral cavity as osteomas of the jaws, odontomas, and abnormal tooth counts. The underlying cause of GS is attributed to mutations in the APC gene. Mutations in this gene disrupt the normal functioning of the protein and lead to the development of GS. To further investigate GS, a family affected by the syndrome was selected from Dongguan, Guangdong Province. The family members underwent a comprehensive survey, which involved collecting clinical data and peripheral venous blood samples. The samples were then used for genetic analysis. Whole exome sequencing (WES) and Sanger sequencing techniques were utilized to screen and identify specific mutation sites in the APC gene. The clinical findings for the GS family included the presence of gastrointestinal polyps and odontomas. After analyzing the genetic sequencing results, a novel mutation site c.4266dupA on the APC gene was found in the patients, which leading to the APC protein truncation. As a result of this study, it is suggested that odontoma may be an early indicator of GS. Additionally, the identification of this novel mutation site in the APC gene expands the known spectrum of genetic mutations associated with the disease. This discovery has significant implications for the early diagnosis of GS, thus enabling timely intervention to reduce the risk of developing colon cancer and other related diseases.

Abstract
Gardner syndrome (GS) is a rare genetic disorder characterized by numerous intestinal colon polyps with various extraintestinal manifestations. Osteomas are a known extracolonic manifestation of GS and can affect the orbit, as seen in our patient, as well as 13 other cases documented in literature. Excision of large orbital osteomas can be successful with a multi-disciplinary approach as presented in this article. Ophthalmologists can even be the first to diagnose GS, usually via the presence of congenital hypertrophy of the retinal pigment epithelium (CHRPE) lesions. Untreated, 100% of colon polyps will transform into cancer, thus it is important to be aware of this rare syndrome with ophthalmic manifestations and screen patients with osteomas for GS.

Abstract
RATIONALE Gardner syndrome is a rare autosomal dominant disorder with a high degree of penetrance, which is characterized by intestinal polyposis, osteomas, and dental abnormalities. Majority of patients with Gardner syndrome will develop colorectal cancer by the age of 40 to 50 years. Mutations in the adenomatous polyposis coli gene are supposed to be responsible for the initiation of Gardner syndrome. PATIENT CONCERNS A 22-year-old Chinese female was admitted to our hospital due to abdominal pain and bloody stool. DIAGNOSIS The patient presented with multiple intestinal polyposis, desmoid tumors, and dental abnormalities was diagnosed as Gardner syndrome and further examination revealed a colon tumor. INTERVENTIONS AND OUTCOMES Patients were implanted with stents to alleviate bowel obstruction, and were treated with oxaliplatin combined with 5-Fu for 4 cycles, but the efficacy was not good. We performed next generation sequencing of 390 genes for the tumor specimens. We detected adenomatous polyposis coli E1538Ifs∗5, KRAS G12D, NF1 R652C, loss of SMAD4, TP53 R175H, IRF2 p.R82S, TCF7L2 p.A418Tfs∗14, and SMAD4 p.L43F in this patient. LESSONS We reported serial mutations in key genes responsible for initiation and progression of colorectal cancer from a patient with Gardner syndrome.

Abstract
Attenuated adenomatous polyposis (AAP) is a poorly understood syndrome, that can be defined as the presence of 10-99 synchronous adenomas in the large bowel, and it is considered a phenotypic variant of familial adenomatous polyposis (FAP). This definition has the advantage of simplicity, but it may include sporadic multiple adenomas of the large bowel at an extreme, or FAP cases on the other side. AAP shows a milder phenotype than FAP, with an older age of onset of adenomas and cancer, and less frequent extracolonic manifestations. AAP may be diagnosed as a single case in a family or, less frequently, it may be present in other family members, and it shows distinct pattern of inheritance. In less than 50% of cases, it may be caused by adenomatous polyposis coli (APC) or MUTYH mutations, referred to as APC-associated polyposis, inherited as an autosomal dominant trait, or MUTYH-associated polyposis, which shows an autosomal recessive mechanism of inheritance, respectively. Surveillance should rely on colonoscopy at regular intervals, with removal of adenomas and careful histological examination. When removal of polyps is not possible or advanced lesions are observed, the surgical approach is mandatory, being subtotal colectomy with ileo-rectal anastomosis the treatment of choice. Studies on this syndrome are lacking, and controversies are still present on many issues, thus, other clinical and genetic studies are requested.

Abstract
AIM To describe the case of metachronous gastrointestinal stromal tumors in a proband with familial adenomatous polyposis (FAP), carrier of APC gene mutation in codon 1309. MATERIAL AND METHODS The physical examination, genealogical analysis and molecular genetic analysis of peripheral blood in 15-years-old girl with FAP and her sister, were carried out. Macroscopic, standard histological and immunohistochemical study of surgical specimens - intraintestinal tumors of the small intestine in proband was performed. RESULTS Extraintestinal manifestations, including congenital abnormalities of facial skeleton, typical for Gardner's syndrome, were observed in the sisters with FAP as the addition symptoms of the disease. Frameshift mutation in codon 1309 in the APC gene was detected in these patients. A rare neoplasia - metachronous gastrointestinal stromal tumor was found in proband 15 months after total colectomy for FAP. This is the third case described in the accessible medical literature. CONCLUSION The possible role of APC gene mutation in the development of mesenchymal neoplasms is discussed. The study of stromal tumors is important for understanding of their pathogenesis that will enable to develop effective targeted therapy.

Abstract
Familial adenomatous polyposis (FAP) or Gardner’s syndrome is often accompanied by adenomas of the stomach and duodenum. We experienced a case of adenomas of the common bile duct in a 40-year-old woman with FAP presenting with acute cholangitis. Only 8 cases of adenomas or adenocarcinoma of the common bile duct have been reported in the literature in patients with FAP or Gardner’s syndrome. Those patients presented with acute cholangitis or pancreatitis. Local excision or Whipple procedure may be the reasonable surgical option.

Abstract
BACKGROUND AND AIMS Classic autosomal-dominant familial adenomatous polyposis (FAP) is clinically defined by the development of hundreds to thousands of colorectal adenomas beginning in childhood and adolescence. A variant of FAP characterized by polyposis in combination with osteomas or soft tissue tumours is called Gardner's syndrome. FAP is caused by germline inactivation of the APC (adenomatous polyposis coli) tumour-suppressor gene located on the long arm of chromosome 5 (5q21-5q22). Cytogenetically visible deletions of chromosome 5q encompassing APC have very rarely been reported. Here, we aimed to phenotypically and genetically characterize a patient with a heterozygous 5q deletion resulting in Gardner's syndrome. METHODS AND RESULTS A 26-year-old female patient with mild mental handicap and dysmorphic features due to a cytogenetically visible deletion on chromosome 5q (microscopically estimated region 5q14-5q23) presented at our tertiary referral centre because of mild adenomatous polyposis (<500 polyps). Twenty months after prophylactic proctocolectomy with definitive ileostomy, three rapidly growing desmoids were observed. Tumour-associated complications necessitated a multidisciplinary approach including medical treatment, surgery and radiation therapy. The characterization of the deletion by comparative genomic hybridization identified a large 5q deletion expanding over a 20-Mb region (5q21.3-5q23.3) including the APC gene. CONCLUSION Chromosome deletions must be suspected in patients presenting with FAP together with mental handicap and dysmorphic features. This case also impressively shows that FAP-associated desmoids need multimodal treatment taking into account the patient's individual symptoms, disease progression and tumour location.

Abstract
In the tooth eruption mechanism, various disturbances can appear as a result of gene mutations, a consequence of which can be that tooth eruption does not occur. There are 5 syndromes which involve the complete failure of several or even all teeth to erupt, specifically: cleidocranial dysplasia, Gardner's syndrome, osteopetrosis, mucopolysaccharidosis and GAPO syndrome. Some are very rare and will seldom be encountered in a dental practice, but they show how vulnerable the tooth eruption mechanism is. Dentists are generally the ones who identify a tooth eruption problem in a patient. Since syndromes can be associated with other disorders, additional investigation by a clinical geneticist is always important when a syndrome is suspected.

Abstract
Approximately 5% of differentiated thyroid carcinomas with follicular cell differentiation, papillary thyroid carcinoma (PTC) and follicular thyroid carcinoma (FTC) and 25-30% of medullary thyroid carcinoma (MTC) are hereditary. They occur either as part of a defined syndrome or are confined to the thyroid gland. Compared to their sporadic non-hereditary counterparts hereditary thyroid carcinomas generally develop earlier and regularly show multifocal tumour growth. With the exception of familial MTC, which is preceded by neoplastic C cell hyperplasia, no precursor lesions of hereditary thyroid carcinoma are known. In strong correlation with the localisation of the germline mutation of the RET protooncogene, familial MTC shows a distinct clinical course which allows precise clinical decision-making for prophylactic thyroidectomy to prevent invasive MTC. According to current knowledge prophylactic thyroidectomy of all other types of hereditary thyroid carcinoma is not justified.

Abstract
BACKGROUND Approximately 5% of the nonmedullary thyroid cancers are hereditary. Hereditary nonmedullary thyroid cancer may occur as a minor component of familial cancer syndromes (familial adenomatous polyposis, Gardner's syndrome, Cowden's disease, Carney's complex type 1, Werner's syndrome, and papillary renal neoplasia) or as a primary feature (familial nonmedullary thyroid cancer [FNMTC]). The goal of this article was to review our current knowledge on the hereditary nonmedullary thyroid cancer. SUMMARY Epidemiologic and clinical kindred studies have demonstrated that FNMTC is a unique clinical entity. Most studies suggest that FNMTC is associated with more aggressive disease than sporadic cases, with higher rates of multicentric tumors, lymph node metastasis, extrathyroidal invasion, and shorter disease-free survival. A hereditary predisposition to nonmedullary thyroid cancer is well established, but the susceptibility genes for isolated FNMTC have not been identified. However, additional susceptibility loci for FNMTC have been recently identified in classic isolated cases of FNMTC (1q21, 6q22, 8p23.1-p22, and 8q24). CONCLUSIONS More studies are needed to validate chromosomal susceptibility loci and identify the susceptibility genes for FNMTC. The discovery of the predisposing genes may allow for screening and early diagnosis, which could lead to improved outcomes for patients and their families.

Abstract
Familial adenomatous polyposis (FAP) is an inherited condition causing numerous adenomatous colorectal polyps and a markedly elevated risk of colon cancer. FAP may be associated with various extracolonic manifestations such as desmoid fibromatosis and osteomas (termed Gardner's syndrome) and brain tumors, usually medulloblastoma or glioma [termed Brain Tumor Polyposis (BTP) syndrome type 2]. We describe a pediatric patient who initially presented with prolactinoma and later was found to have Gardner's syndrome. A germline mutation of the APC (adenomatous polyposis coli) gene was identified. Our case illustrates the association between prolactinoma and FAP, which may represent a rare subtype of Gardner's and BTP syndromes.

Abstract
Mesenteric fibromatosis is currently a diagnostic and therapeutic challenge. We report a case of mesenteric fibromatosis in a 29-year-old man with a 2-month history of periumbilical fullness who was discovered to have an abdominal mass with hydronephrosis. To the best of our knowledge, we report the first case of hydronephrosis in a mesenteric fibromatosis with Gardner's syndrome, which was successfully treated with a cyclo-oxygenase 2 inhibitor without surgical removal of the mesenteric fibromatosis. The hydronephrosis and mesenteric fibromatosis improved modestly with long-term celecoxib (200 mg twice daily). Our case also highlights the importance of performing a detailed examination in patients with hydronephrosis.

Abstract
Gardner's syndrome is a rare variant of the Familial Adenomatous Polyposis (FAP) in which affected individuals develop thousands of polyps within the gastrointestinal tract, with a 100 % risk of eventual malignant change. They also have a variety of extraintestinal abnormalities - various soft and hard tissues tumors like fibroma, osteoma, epidermoid cysts, sebaceous cysts on the scalp. Gardner's syndrome is an autosomal dominant disease, caused by mutations in APC ( adenomatous polyposis coli ) gene, which is located in chromosomal locus 5q21- q22. Firstly it has been described in 1953 by Gardner and Richards. They have investigated a family of 51 members with polyposis, some of them with multiple epidermoid cysts, fibromas and jaw osteomas. Eight of them have died by colorectal carcinoma. If undetected or untreated virtually all patients develop colonic carcinoma at a young age. Due to this high risk of malignancy the patients with Gardner's syndrome usually undergo surgical treatment by total or subtotal proctocolectomy. We report a case with Gardner's syndrome - a 36 year-old male who has been operated on in Department of Surgery in Vth city clinical hospital in October 2003. He had multiple adenomatous polyposis of colon, rectal cancer, osteomas of skull bones, subcutaneous fibromas and lipomas. We discovered also by ultrasound examination a polyp of gall bladder. His father has had also multiple polyposis with malignancy and metastatic lesions and he has died at age of 49 years. We performed total proctocolectomy with definitive iliac anus and cholecystectomy.

Abstract
✓The authors report on the case of a craniopharyngioma arising in the cerebellopontine angle (CPA) in a patient with Gardner syndrome. Although familial adenomatous polyposis (FAP) is associated with intracranial neoplasms, the current case is only the third reported craniopharyngioma in a patient with Gardner syndrome. Two of these tumors, including that of the current case, originated in the CPA, an unusual location for craniopharyngiomas. The literature concerning FAP and its associations with intracranial neoplasia, as well as the pathogenesis of craniopharyngiomas in the posterior fossa, is discussed.

Abstract
Gardner syndrome is characterized by the triad of colorectal adenomas, soft and hard tissue tumors. This disorder was regarded as a separate disease until the identification of the APC gene when it was recognized that mutations in the APC gene were the underlying cause of both Gardner syndrome and familial adenomatous polyposis (FAP). The present study aimed at examining whether a particular APC genotype could be delineated in FAP patients with benign extracolonic manifestations: sebaceous cysts and/or osteomas. A questionnaire was sent to all Danish FAP patients (N = 234) asking for occurrence of sebaceous cysts and palpable osteomas. Medical records later verified positive findings, when possible. The results for each patient were correlated to the position of his or her mutation in the APC gene. Positive participation compliance was 77% (N = 180), and in 105 of these patients the pathogenic APC mutation was known. Palpable osteomas were reported in 17 of the patients in whom a pathogenic mutation had been identified. Osteomas were only identified in patients with mutations between codon 767 and 1513, a gene area also associated with congenital hypertrophy of the retinal-pigmented epithelium (CHRPE) and hepatoblastoma. Sebaceous cysts were reported in 51% of the patients, and their APC mutations were evenly distributed in the gene with no particular hotspot. Osteomas appeared most frequently in patients with sebaceous cysts, odds ratio 6.6, P < 0.001. The study provides molecular evidence that Gardner syndrome is a variant of FAP and essentially obsolete in clinical practice.

Abstract
Familial adenomatous polyposis (PAF) associated to soft tissue tumors or osteomas constitutes the Gardner's syndrome of autosomal dominant inheritance. The risk of colorectal cancer in these patients is 100%. We present a patient with Gardner's syndrome who was had colectomy at early age. An eleven years old boy he was evaluated due to a family history of PAF and subcutaneous tumors (occipital and left thigh). Genetic profile shows a mutation in gene APC and the colonoscopy confirms the polyposis; the biopsy also suggested moderate dysplasia. When the patient reached the age of twelve, a total colectomy with colorectal mucosectomy was performed. Cystic subcutaneous lesions (epidermoid cysts) were also excised. In the postoperative period there were no complications. The prophylactic colectomy, is the only effective treatment to prevent the colorectal cancer. Gardner's syndrome patients requires periodic controls to rule out the appearance of new tumors or anomalies in the retine. The duodenoscopy is essential in the follow up of these patients because of the frequency of duodenal affectation.

Abstract
Gardner syndrome is a variant of familial adenomatous polyposis characterized by intestinal adenomatous polyps, which can progress to adenocarcinoma, and a variety of extraintestinal manifestations, including skin cysts, osteomas, soft tissue fibrous tumours and a characteristic ocular lesion. The extraintestinal manifestations are often the presenting feature but are usually not sufficiently characteristic on their own to trigger recognition of the syndrome. We report a case of a 17-year-old female who had been treated by a number of specialists over a 13-year period for a variety of cutaneous lesions without a hereditary condition being suspected. Gardner syndrome was considered only after excision of subcutaneous fibrous tumours from the mastoid region and paraspinal area and was confirmed by genetic testing in spite of the patient's refusal to undergo colonic endoscopic examination. Subsequent resection revealed approximately 70 adenomatous colonic polyps in the colon and rectum but no invasive tumour, highlighting the benefits of genetic testing in treatment planning.

Abstract
Familial Adenomatous Polyposis (FAP) and its phenotype variant, Gardner's syndrome, constitute a rare autosomal dominant inherited disorder. They are characterised by the development, generally during the second and third decades of life, of multiple adenomatous polyps in the colon and rectum. These polyps have a high risk of subsequently becoming malignant, which normally occurs in the third and fourth decades of life. The phenotypical features of FAP can be very variable. As well as colorectal polyps, these individuals can present with extra-colonic symptoms, among which are particularly: gastro-duodenal polyps, dermoid and epidermoid cysts, desmoid tumours, congenital hypertrophy of the retinal pigment epithelium, disorders of the maxillary and skeletal bones and dental anomalies. In this paper the most important aspects of this syndrome are reviewed, showing an example based on a well documented clinical case. The importance of odonto-stomatological examinations should be pointed out, among others, as a means of reaching a presumptive diagnosis, whose confirmation is vital to the patient.

Abstract
Patients suffering from familial adenomatosis polyposis develop multiple pre-malignant gastrointestinal polyps and are at high risk of developing colon cancer. In addition extra-intestinal manifestations are observed frequently. The combination of extra-intestinal manifestations and familial adenomatosis polyposis is named Gardner's syndrome. An early diagnosis of this disease is important because it could mean a better prognosis for the patient. This review describes the oral and maxillofacial symptoms of FAP, and its potential implications for dental treatment.

Abstract
Familial adenomatous polyposis (FAP) is a colon cancer predisposition syndrome in which hundreds to thousands of precancerous colonic polyp become evident at a mean age of 16 years (range, 7-36 years). By age 35 years, 95% of patients have polyps. Gardner syndrome is the eponym given to a subgroup of FAP with extracolonic manifestations, such as pigmented ocular fundus lesions that resemble congenital hypertrophy of the retinal pigment epithelium, among others.

Abstract
Though rare, Gardner's syndrome is a systemic disease with frequent jawbones involvement. Dento-maxillo-facial lesions both in early and in advanced stages should be known by dentists and other specialists. In fact, these lesions should be sought in patients with intestinal polyposis, while they could be the first sign of Gardner's syndrome not yet diagnosed.

Abstract
Familial adenomatous polyposis (FAP) is an autosomal dominant, hereditary colon cancer syndrome that is characterized by the presence of innumerable adenomatous polyps in the colon and rectum. Gardner's syndrome is a variant of FAP, which in addition to the colonic polyps, also presents extracolonic manifestations, including desmoid tumors, osteomas, epidermoid cysts, various soft tissue tumors, and a predisposition to thyroid and periampullary cancers. Mutations of the APC gene are thought to be responsible for the development of FAP, and the location of the mutation on the gene is thought to influence the nature of the extracolonic manifestations that a given patient might develop. Though patients are often asymptomatic, bleeding, diarrhea, abdominal pain and mucous discharge frequently occur. Diagnostic tools include genetic testing, endoscopy, and monitoring for extra-intestinal manifestations. Currently, surgery is the only effective means of preventing progression to colorectal carcinoma. Restorative proctocolectomy with ileal pouch anal anastomosis (RPC/IPAA) with mucosectomy is the preferred surgical procedure, since it attempts to eliminate all colorectal mucosa without the need for an ostomy. Periampullary carcinoma and intra-abdominal desmoid tumors are a significant cause of morbidity and mortality in these patients after colectomy. Frequent endoscopy is needed to prevent the former, while there is no definitive treatment available yet for the latter. The following article presents a case and reviews the evaluation, management and treatment of Gardner's syndrome.

Abstract
Gardner syndrome, a variant of familial adenomatous polyposis, is an autosomal dominant disease characterized by gastrointestinal polyps that develop in the colon as well as in the stomach and upper intestine (duodenum), multiple osteomas, and skin and soft tissue tumors. Cutaneous findings include epidermoid cysts, desmoid tumors, and other benign tumors. Polyps have a 100% risk of undergoing malignant transformation; consequently, early identification and therapy of the disease are critical. Osteoma is a benign neoplasm of bone tissue that is characterized by slow continuous growth and is the most common accompanying bone lesion seen in Gardner syndrome. The authors report a case of Gardner syndrome that was operated on because of the mandibular osteoma.

Abstract
Polyposis of the colon is a colon cancer predisposition syndrome. Familial adenomatous polyposis (FAP) accounts for 1% of the cases of inherited colorectal cancer (CRC). The National Register of inherited CRC and polyposis of the intestines keeps track of 18 patients from 14 families with FAP. Eight of them have been operated of CRC, on 6 patients preventive colectomy with ileorectal anastomosis has been done and four patients refused surgery. Colectomy has been done due to the malignant development also on a female patient with difused juvenile polyposis with adenomatosis. Of three patients under surveillance with the Peutz-Jeghers syndrome, surgery has been done on one female patient with ileus and bleeding large polyps.

Abstract
A 25-year-old man with suspected Gardner syndrome was introduced to our hospital by a dentist who, during examination of the patient, had found dental dysplasias and multiple osteomas of the jaw. Radiographs, endoscopy and biopsies revealed adenomatous polyposis of the colon. Genetic analysis of peripheral lymphocytes revealed a one-base deletion at codon 1556 in exon 15 of APC, which caused a frame shift and a premature stop at codon 1564. The pedigree analysis demonstrated five patients in his family who presented with dental abnormality and osteomas in addition to adenomatous polyposis of the colon. Although the relationship between the location of APC mutations and dental abnormalities remains controversial, this case supports the hypothesis that a mutation at around codon 1556 of APC is closely associated with dental abnormality and osteomas.

Abstract
Gardner syndrome, a phenotypic variant of familial adenomatous polyposis, is characterized by the classical clinical triad of skin and soft tissue tumours, osteomas and intestinal polyposis, but disease patterns with pairs of these findings have also been reported. Different mutations in the adenomatous polyposis coli (APC) gene have been shown to be associated with Gardner syndrome disease phenotypes. A 36-year-old patient presented with multiple epidermal cysts on the face, left ear lobe and neck, and the possible diagnosis of Gardner syndrome was based on the additional findings of two classical osteomas in the left radius and ulna and a cold non-malignant nodule of the thyroid gland. Intestinal polyposis was lacking at the time of examination. Major deletions but not microdeletions were excluded by a cytogenetic analysis with 650 chromosomal bands per haploid set. Systematic sequencing of the entire coding region of the APC gene (> 8500 bp) of the patient and five healthy controls was also performed. As a results, new APC gene polymorphisms were identified in exons 13 [A545A (A/G)] and 15 [G1678G (A/G), S1756S (G/T), P1960P (A/G)]. We also detected D1822V (A/T) which has recently been reported to be potentially related to colorectal carcinoma, and genotyped 194 randomly chosen healthy individuals from the Glasgow area for this as well as for the above variants in exons 13 and 15. Interestingly, of the 194 controls, 112 carried the DD (57.7%), 71 the DV (36.6%), and the remaining 11 (5.7%), including our patient, the VV genotype. It is therefore unlikely that APC D1822V serves as an important marker for colorectal carcinoma. In conclusion, we failed to identify obvious germline candidate mutations in > 8500 bp of the coding region of the APC gene in a patient with multiple epidermal cysts, osteomas and a thyroid gland nodule; major chromosomal deletions were excluded. Therefore, we assume that only the presence of intestinal polyposis is a marker for Gardner syndrome.

Abstract
Congenital hypertrophy of the retinal pigment epithelium (CHRPE) can be associated with Gardner's syndrome (GS). During childhood multiple adenomatose polyps develop in the colon ascendens (familiar-autosomal Polyposis coli [FAP]), and always become malignant until the age of 35. The tumour-suppressive FAP-gen was identified at the long arm of chromosome 5 (5q21). Ophthalmic funduscopy is very important. Patients with more than 3 CHRPE in one eye or a bilateral CHRPE, as well as patients with a positive family history and one unilateral solid CHRPE require further gastroenterological evaluation.

Abstract
In the last few years, problems relating to genetic determination of colorectal carcinoma are comprehensively discussed by a number of authors. The new elaborations concerning the familial polypoid and carcinoid syndromes discovered, as well as molecular researches along this line answer a great number of questions posed in connection with substantiating the old idea about many-staged cancerigenesis. As much as 94 per cent of colorectal carcinoma cases are assigned to the sporadic cancer diagnosis category. Familial polyposis accounts for 1 per cent of all neoplasms of the colon, while the remainder 5 per cent make part of diverse familial carcinoid syndromes. Most of the data on genetic etiology of colorectal carcinoma so far elucidated are presented in a summed up fashion.

Abstract
Gardner's syndrome is a congenital condition characterised by diffuse intestinal adenomatous polyposis (IAP) associated with maxillary osteomas, odontomas, hypertrophy of the retinal epithelium and skin tumours. It may affect subjects of all ages with equal frequency in males and females. The fact that diffuse adenomatous polyposis, the most serious clinical aspect of the syndrome, is treated surgically, has led to improved survival in patients and, consequently, an increased incidence in associated lesions, particularly maxillary osteomas. A personal case observed at the Odontostoma-tological Clinic of the University of Rome La Sapienza is reported.

Abstract
INTRODUCTION Familial adenomatous polyposis (FAP) is associated with malignant tumors of the central nervous system, predominantly medulloblastomas and glioblastoma multiforme (Turcot's syndrome) and with craniofacial osteomas (Gardner's syndrome). This report details the occurrence of benign, intracranial tumors in two related individuals with Gardner's syndrome, an association not previously described. PATIENTS AND METHODS A 57-year-old woman (the propositus), her sister, two of her nieces and one of her grandnephews were previously diagnosed with Gardner's syndrome. The propositus came to neurosurgical attention because of vertigo associated with what proved to be an epidermoid cyst of the cerebellopontine angle. Her unaffected children and her relatives with Gardner's syndrome were examined and underwent computed tomography or magnetic resonance imaging. RESULTS A 39-year-old woman with Gardner's syndrome, the niece of the propositus, was found to harbor an asymptomatic left frontal meningioma. DISCUSSION Familial adenomatous polyposis, Gardner's syndrome, and that variant of Turcot's syndrome in which medulloblastoma predominate, are associated with a mutation of the adenomatous polyposis coli gene. The demonstration that patients with Gardner's syndrome can also have benign, nonneuroglial, intracranial tumors adds to the previously known extracolonic lesions associated with FAP. The molecular characterization of our patients should reveal if benign intracranial tumors represent a pleiotropic manifestation of the adenomatous polyposis coli gene mutation or if other genes are implicated.

Abstract
INTRODUCTION Familial adenomatous polyposis (FAP) is an autosomal dominant disorder which typically presents with colorectal cancer in early adult life secondary to extensive adenomatous polyps of the colon. Gardner's syndrome is a variant of FAP in which desmoid tumors, osteomas and pigmented retinal lesions occur together with intestinal manifestations. The APC gene (adenomatous polyposis coli) at 5q21 is a tumor suppressor gene which is mutant in FAP. PATIENT A 36 year old woman presented with a history of polyposis ventriculi, ovarian desmoid cysts, and disseminated desmoid tumors. Her familial history was unremarkable. On admission she complained weight gain, secondary amenorrhea, and episodes of hypertension followed by paroxysmal headache. RESULTS Elevated urinary free cortisol (878 microg/24h), suppressed basal ACTH (< 5 pg/ml) and insuppressible serum cortisol after low dose dexamethasone (189 ng/ml) revealed adrenal Cushing's syndrome. Abdominal NMR showed an adrenal mass two centimeter in diameter with inhomogeneous contrast enhancement. Unilateral adrenalectomy was performed and an adrenal adenoma was diagnosed by histological criteria. For mutational detection DNA from peripheral blood leucocytes was extracted. A protein truncation test was performed, which revealed a termination mutation between codon 1099 and 1623 of the APC gene. Direct sequencing showed a point mutation in exon 15 of the APC gene at position 1542 (CAG --> TAG). This region is known to be altered in patients with extraintestinal manifestation of FAP. CONCLUSION In patients with Gardner's syndrome adrenal tumors leading to hormonal excess should be considered. Whether mutations in the APC gene have implications in sporadic adrenal tumorigenesis needs to be proven.

Abstract
BACKGROUND Familial adenomatous polyposis (FAP) is a familial cancer syndrome in which affected individuals develop multiple adenomatous polyps and are thereby at greatly increased risk of developing colorectal cancer. Gardner syndrome is a variant of FAP, in which the patients also develop extraintestinal tumors, in particular osteomas and desmoid tumors. An attenuated form of the disease (AFAP) is associated with fewer polyps, but still a high risk for colorectal cancer. Germline mutations in the adenomatosis polyposis coli (APC) gene cause FAP and Gardner syndrome and have recently been associated also with the development of AFAP. METHODS We have analysed the entire APC gene for germline mutations in 7 patients with FAP and in 6 patients with suspected AFAP. Mutation screening was performed by direct sequencing of exons 1-14 and using the protein truncation test for analysis of exon 15. RESULTS Novel disease-causing germline mutations, all of which resulted in truncation of the APC protein, were identified in 6 of the 7 patients with FAP or Gardner syndrome. No APC mutation was detected in any of the 6 patients with suspected AFAP. CONCLUSIONS This study reports novel FAP- and Gardner syndrome-causing mutations in the APC gene. The lack of APC mutations in patients with multiple polyps at young age indicates that other genetic defects may cause this phenotype.

Abstract
UNLABELLED Familial cancer syndromes reflect an inherited predisposition to develop benign and malignant tumors. Clinically, the cancers occur at an earlier age and involve multiple foci of tumor formation at multiple sites. In the past 10 years, the molecular basis of many of these cancer syndromes have been unraveled with the advent of powerful genetic technologies. Entities which were hypothesized to be related on the basis of clinical features have now been shown to be linked or disparate through genetic analysis. This article reviews some of the recent advances in the clinical and molecular aspects of familial cancer syndromes that involve the skin. (J Am Acad Dermatol 2000;42:939-69.)

Abstract
Although everybody is at some risk of developing cancer, individuals whose families show certain characteristics might be at high risk. The existence of families with hereditary cancers have been known for a long time. Meanwhile several genes for these dispositions have been identified, which gives high-risk individuals the opportunity to choose presymptomatic testing. This leads to a new group of "patients", the healthy gene carriers. Genetic counselling is a process which includes verification of diagnosis, pedigree analysis, individual risk assessment, explanation of complex medical and genetic facts and the choice of possible options to deal with the genetic burden (e.g. coping strategies, prevention). Presently cancer gene testing has 2 clinical applications. In affected individuals it is part of the diagnostic procedure, in at risk individuals it segregates gene carriers from non-carriers. With regard to the healthy carriers of highly penetrant mutated genes and to some extend also with regard to the non-carriers this means new medical, psychological, social and ethical tasks. Genetic counselling should be offered to any family with a history of cancer or cancer-linked conditions. It has to be considered that not only patients and their families are laymen with regard to medicine, but that we all are laymen with regard to the leading a life with the knowledge of once own deleterious heritage.

Abstract
Recent advancement of molecular biology disclose responsible genes of FAP(familial adenomatous polyposis) and HNPCC(hereditary non polyposis colorectal cancer). Gardner Syndrome is now categorized as subtype of FAP. Turcot Syndrome is now known as a heterogeneous disease. Turcot Syndrome caused by APC gene develops medulloblastoma and Turcot Syndrome caused by mismatch repair gene develops glioblastoma. Because of the discovery of APC gene, the presymptomatic diagnosis of asymptomatic gene carriers are now available and preventive surgery can be planned. FAP patients with mutated APC gene between codon 1250 and 1464 shows severe phenotype. It is known that FAP patient whose APC gene mutation locates at codon 1309 develops cancer 10 years earlier in comparison to the rest of the cases. Consequently risky rectal mucosa should be removed in this group of patients. As for HNPCC, presymptomatic diagnosis is still not possible because the penetrance rate has not been estimated yet and some additional responsible genes are expected to be discovered. Replication error, mutator phenotype of mismatch repair gene is useful indicator to predict second primary cancers. When the patient in a HNPCC family develops adenoma with microsatellite mistability, preventive colectomy might be one of the surgical option with the informed consent of the patient.

Abstract
PURPOSE Gardner syndrome, a variant of familial adenomatous polyposis, is characterized by colonic polyps that undergo malignant change and benign and malignant extracolonic lesions. Tumors frequently associated with Gardner syndrome include carcinoma of the ampulla of Vater, papillary carcinoma of the thyroid, and, in children, hepatoblastoma. The childhood malignancies often precede the appearance of other manifestations by several years. PATIENTS AND METHODS Two patients are described. Gardner syndrome was diagnosed in a 15-year-old girl with fibrolamellar hepatocellular carcinoma after desmoid tumors and colonic polyposis developed. Classic hepatocellular carcinoma was also diagnosed in a 9 1/2-year-old boy with familial adenomatous polyposis. RESULTS In patient 1, the diagnosis of fibrolamellar hepatocellular carcinoma preceded the diagnosis of Gardner syndrome by almost 2 years. The diagnosis was confirmed by identifying a germline mutation of the adenomatous polyposis coli (APC) gene. This is the first patient reported with fibrolamellar hepatocellular carcinoma associated with Gardner syndrome. Patient 2 had a strong family history of familial adenomatous polyposis but no manifestations of Gardner syndrome. He was not tested for the APC mutation. The current literature and previously reported cases of hepatocellular carcinoma in patients with Gardner syndrome or familial adenomatous polyposis are reviewed. CONCLUSIONS Because hepatocellular carcinoma is uncommon in the pediatric and adolescent population, it is important to consider the possibility of Gardner syndrome or familial adenomatous polyposis in these patients.

Abstract
Variegate porphyria (VP) is an autosomal dominant disorder characterised by a partial defect in the activity of protoporphyrinogen oxidase (PPO), and has recently been genetically linked to the PPO gene on chromosome 1q22-23 (Z=6.62). In this study, we identified a mutation in the PPO gene in a patient with VP and two unaffected family members. The mutation consisted of a previously unreported T to C transition in exon 13 of the PPO gene, resulting in the substitution of a polar serine by a non-polar proline (S450P). This serine residue is evolutionarily highly conserved in man, mouse, and Bacillus subtilis, attesting to the importance of this residue. Interestingly, the gene for Gardner's syndrome (FAP) also segregates in this family, independently of the VP mutation. Gardner's syndrome or familial adenomatous polyposis (FAP) is also an autosomal dominantly inherited genodermatosis, and typically presents with colorectal cancer in early adult life secondary to extensive adenomatous polyps of the colon. The specific gene on chromosome 5 that is the site of the mutation in this disorder is known as APC (adenomatous polyposis coli), and the gene has been genetically linked to the region of 5q22.

Abstract
This study was conducted to clarify the actual morbidity and clinicopathologic features of thyroid neoplasia in patients with familial adenomatous polyposis. We analyzed the clinical records of 49 Japanese patients with familial adenomatous polyposis diagnosed at our institute. Six of these patients had thyroid neoplasias (3 carcinomas, 2 adenomas, and 1 of unknown histology). Among 17 patients (11 men and 6 women) who had been examined by thyroid ultrasonography or in whom postmortem examination was performed; we categorized 6 patients with thyroid tumor as the TT group, and the remaining 11 without thyroid tumor as the NTT group. The clinical features of the two groups were compared. Thyroid neoplasia was detected by physical examination in 2.3% of 43 patients so examined and was detected in 25% of 8 patients examined by thyroid ultrasonography, and in 44% of the 9 patients subjected to postmortem examination. There were no significant differences between the TT and NTT groups in gender; age at first admission, colectomy, and last follow-up visit; number of colonic polyps; or in presence of colorectal cancers, gastroduodenal adenomas, gastric fundic gland polyposis, retinal pigmented lesions, or extraintestinal tumors. The thyroid gland is frequently affected in patients with familial adenomatous polyposis, but there may be no association between thyroid neoplasia and other clinical manifestations.
