Abstract
A relatively rare inherited condition known as Peutz-Jeghers syndrome (PJS) causes mucocutaneous pigmentation and gastrointestinal hamartomatous polyps. These polyps are non-cancerous, but the presence of PJS significantly increases the chances of developing various types of cancers, such as colorectal, pancreatic, gastric, and breast cancer. The purpose of this review article is to give an abbreviated summary of what is currently known about this syndrome, covering its clinical symptoms, pathophysiology, genetics, and management. PJS also raises the risk of getting many malignancies, especially gastrointestinal and pelvic cancers. Symptoms of the gastrointestinal tract brought on by hamartomatous polyps are frequent and include stool blockage, bleeding, and stomach pain. The pigmentation commonly appears as prominent bluish-black macules and frequently affects the skin and mucous membranes. Small macules and large regions of lentiginous pigmentation are both possible. Numerous areas, including the perioral area, buccal mucosa, fingers, and lips, exhibit pigmentation. Bowel obstruction and intussusception risk can be decreased by early identification and routine surveillance of gastrointestinal polyps. The gene serine/threonine kinase 11 (STK11) controls several biological functions, including cell polarity, growth, and proliferation. Genetic counseling is recommended for the affected individuals and their families. This can help assess the risk of passing on the condition to future generations and provide information about available reproductive options. Regular surveillance is crucial for managing the syndrome and reducing the risk of cancer development. Other syndromes and extra-gastrointestinal characteristics, such as somatic tumor polyps outside the gastrointestinal tract, are also linked to this syndrome.

Abstract
Solitary hamartomatous polyps with identical pathological features of the typical hamartomas of the Peutz-Jegher syndrome are extremely rare. These solitary lesions lack the associated intestinal polyposis, classic mucocutaneous pigmentation, and family history typifying the Peutz-Jegher syndrome. We describe the case of a 31-year-old woman with a giant solitary gastric hamartoma endoscopically diagnosed and laparoscopically resected.

Abstract
INTRODUCTION AND OBJECTIVES Peutz-Jeghers syndrome is a rare autosomal dominant inherited disease caused by a germline mutation of the STK11/LKB1 gene, located on chromosome 19p13.3. It is characterized by mucocutaneous hyperpigmentation, hamartomatous polyposis, and predisposition to cancer. The aim of the present study was to identify and register patients with Peutz-Jeghers syndrome, describe the disease, and estimate its prevalence in Valencia (Spain). MATERIALS AND METHODS A print-out of the clinical histories from 10 hospitals was obtained utilizing the ICD-9 code 759.6 from the Minimum Basic Data Set of Hospital Admissions of the Spanish Ministry of Health and Consumer Affairs. RESULTS From a total of 405 clinical histories found, 15 (9 males and 6 females) fit the diagnostic criteria of Peutz-Jeghers syndrome. Mean age at diagnosis was 13.8 years and mean age at death was 54.2 years. Four males died, all from cancer. The estimated disease prevalence was 0.4/100,000 inhabitants. All the patients presented with anemia and polyps in the small bowel (80% in the duodenum, 66.7% in the ileum, and 40% in the jejunum), 93.3% underwent urgent surgical intervention and presented with intestinal invagination, and 40% of the patients developed cancer at a mean age of 48.5 years. CONCLUSION The present study is the first register of patients with Peutz-Jeghers syndrome in Valencia, Spain. The ICD-9 code is nonspecific for rare diseases. The duodenum was the most frequent location for polyps and the majority of cases presented with intestinal invagination, bowel obstruction, and urgent surgical intervention. A large percentage of patients presented with cancer. It would be of interest to review and evaluate the existing surveillance protocols in the Valencian Community.

Abstract
OBJECTIVES The present study aims to identify the genotype-phenotype correlation in children with Peutz-Jeghers Syndrome (PJS) through the analysis of STK11 gene mutations in the context of clinical and pathological characteristics. METHOD In this observational cohort study, the clinical characteristics of 18 families diagnosed with pediatric PJS were collected. Genomic DNA from the peripheral blood of affected children and their family members was collected. The coding region of STK11 was amplified by PCR and screened for mutation by Sanger sequencing. The families that were negative for STK11 mutation were further assessed by multiplex ligation-dependent probe amplification (MLPA). RESULT Initial presentation in affected children was at 1.6 to 14.2 years and included anemia in 8 patients whereas 6 presented for screening by virtue of family history. All patients underwent endoscopy, colonoscopy, and polypectomy. Polyps were distributed throughout the gastrointestinal (GI) tract, including the small intestine, stomach, colon, and rectum.In the 18 pediatric PJS families, STK11 mutations were detected in 8 families by Sanger sequencing, and large deletions were detected in 3 by MLPA, respectively. Nine of the 11 STK11 mutations were de novo, 3 were novel (c.419T>C:p.L140P, c.314T>G:p.L105X), and (c.488_489insACGG p.L164fs). CONCLUSIONS Although the main clinical features of pediatric PJS were similar to those of PJS cases in adults, a high frequency of STK11 de novo mutations were encountered in our population of patients with PJS.

Abstract
We conducted a retrospective study based on the Surveillance, Epidemiology, and End Results Program (SEER) database to establish a novel nomogram prognostic prediction system and to estimate the association between overall survival and prognostic factors, as well as to explore surgical treatment strategies for adenocarcinoma of the jejunum and ileum. A total of 883 patients from the SEER database were included in this study. Eight potential prognostic factors were included in a nomogram model and discriminatory power and accuracy were examined using the Harrell's C-index and Akaike Information Criterion (AIC) index. In comparison with the AJCC TNM staging system, the nomogram prediction system was more accurate and homogeneous (Harrell's C-index, 0.731 vs. 0.667; AIC index, 4852.9 vs. 4913.723). For surgical management, resection of more than 12 local lymph nodes could improve the likelihood of survival. This study demonstrates that our nomogram model is more accurate and homogeneous than the traditional AJCC TNM staging system, and proper surgical strategies for mesenteric lymphadenectomy improve overall survival.

Abstract
BACKGROUND AND OBJECTIVE Labial lentigines associated with Peutz-Jeghers syndrome are cosmetically disfiguring and distressful. Although multiple treatment modalities including Q-switched ruby laser and Q-switched alexandrite laser have been proposed, experience with Q-switched Nd:YAG laser has been lacking. This study aimed to retrospectively evaluate the efficacy and safety of Q-switched Nd:YAG laser (532 nm) for labial lentigines in Peutz-Jeghers syndrome. PATIENTS AND METHODS Demographic and clinical data of 11 patients diagnosed with Peutz-Jeghers syndrome were analyzed. A quartile grading system was used. All patients were treated with a Q-switched Nd:YAG laser system with the following parameters: wavelength 532 nm; spot size 3 mm; pulse duration 5-20 ns; fluence 1.8-2.2 J/cm(2) . RESULTS After two to six (mean 3.6) treatment sessions, an average grade of 3.73 was achieved. Eight patients (72.7 %) showed an excellent response with more than 75 % lesion clearance. Three patients (27.3 %) showed a good response. Repeated treatments led to improved clearance of labial lentigines. Age, gender, and Fitzpatrick skin type were not statistically associated with efficacy grades after the first treatment session. Neither recurrence in treated areas nor significant complications were observed. CONCLUSIONS Q-switched Nd:YAG laser provides an effective and safe treatment option for labial lentigines associated with Peutz-Jeghers syndrome.

Abstract
BACKGROUND Several polyposis syndromes of the gastrointestinal tract have been recognized which carry increased risk for cancer and have a genetic predisposition. There is a paucity of literature regarding the occurrence and the burden of colonic polyposis syndromes in the Indian subcontinent. This study attempts to highlight this hitherto unaddressed burden and the associated increased risk for inherited colonic cancer in this geographical location. METHODS A retrospective study of various colonic polyposis syndromes encountered at a tertiary centre in South India over a period of 8 years (2005 to 2012) was performed. The diagnosis in each case was made histologically with clinicopathological correlation. RESULTS Fifty cases were identified as belonging to a colonic polyposis syndrome, during the study period. There were 27 males and 23 females with a median age of 36.5 years (range 19 months to 78 years). The commonest syndrome was familial adenomatous polyposis (n = 27; 54 %) followed by Peutz-Jeghers syndrome (n = 11), attenuated familial adenomatous polyposis (n = 7), juvenile polyposis syndrome (n = 3), hyperplasic polyposis syndrome (n = 1) and Cronkhite-Canada syndrome (n = 1). Colonic malignancy was documented at first presentation in 22 patients (44 %). CONCLUSIONS Our study highlights the various colonic polyposis syndromes encountered in a tertiary care institution in Southern India.

Abstract
Peutz Jeghers syndrome (PJS) is an autosomal dominant disease characterized by hamartomatous polyposis and distinct mucocutaneous pigmentation. PJS is associated with an increased risk for several cancers and other complications such as small intestine intussusception, short bowel syndrome, and anemia. Medical management mainly consists of treatment of the polyps and surveillance. This medical management update will review clinical concepts, therapeutic advances, and emphasize features of PJS important to the oral health care provider.

Abstract
Since the histologic description of the hamartomatous polyp in 1957 by Horrilleno and colleagues, descriptions have appeared of several different syndromes with the propensity to develop these polyps in the upper and lower gastrointestinal tracts. These syndromes include juvenile polyposis, Peutz-Jeghers syndrome, hereditary mixed polyposis syndrome, and the phosphatase and tensin homolog gene (PTEN) hamartoma tumor syndromes (Cowden and Bannayan-Riley-Ruvalcaba syndromes), which are autosomal-dominantly inherited, and Cronkhite-Canada syndrome, which is acquired. This article reviews the clinical aspects, the molecular pathogenesis, the affected organ systems, the risks of cancer, and the management of these hamartomatous polyposis syndromes. Although the incidence of these syndromes is low, it is important for clinicians to recognize these disorders to prevent morbidity and mortality in these patients, and to perform presymptomatic testing in patients at risk.

Abstract
INTRODUCTION We report a case of unusual co-existence of multiple primary neoplasms of female genital tract. CASE A 62-year-old gravida 2, para 2 was referred with spotting and vaginal discharge for about 6 months. Fractionate curettage was performed and documented endocervical squamous cell carcinoma in situ. Subsequently total abdominal hysterectomy and bilateral salphingo-oophorectomy was performed. Final pathological report demonstrated cervical squamous cell carcinoma, right ovarian Brenner tumor, left ovarian granulosa tumor and endometrial polyps. DISCUSSION Multiple primary neoplasms of female genital tract is a well-recognized yet rare occurrence. Although the presented case is probably an incidental event, the pathogenesis of the neoplastic process affecting the tissues with different embryological origin needs further research and evaluation. It is important to distinguish multiple primary neoplasms from metastatic disease because of the fact that overall survival as well as treatment would vary considerably.

Abstract
BACKGROUND Although an increased cancer risk in Peutz-Jeghers syndrome is established, data on the spectrum of tumors associated with the disease and the influence of germ-line STK11/LKB1 (serine/threonine kinase) mutation status are limited. EXPERIMENTAL DESIGN We analyzed the incidence of cancer in 419 individuals with Peutz-Jeghers syndrome, and 297 had documented STK11/LKB1 mutations. RESULTS Ninety-six cancers were found among individuals with Peutz-Jeghers syndrome. The risk for developing cancer at ages 20, 30, 40, 50, 60, and 70 years was 2%, 5%, 17%, 31%, 60%, and 85%, respectively. The most common cancers represented in this analysis were gastrointestinal in origin, gastroesophageal, small bowel, colorectal, and pancreatic, and the risk for these cancers at ages 30, 40, 50, and 60 years was 1%, 9%, 15%, and 33%, respectively. In women with Peutz-Jeghers syndrome, the risk of breast cancer was substantially increased, being 8% and 31% at ages 40 and 60 years, respectively. Kaplan-Meier analysis showed that cancer risks were similar in Peutz-Jeghers syndrome patients with identified STK11/LKB1 mutations and those with no detectable mutation (log-rank test of difference chi2 = 0.62; 1 df; P = 0.43). Furthermore, the type or site of STK11/LKB1 mutation did not significantly influence cancer risk. CONCLUSIONS The results from our study provide quantitative information on the spectrum of cancers and risks of specific cancer types associated with Peutz-Jeghers syndrome.

Abstract
The authors describe a 14-year-old girl with Peutz-Jeghers syndrome who presented with progressive abdominal distention. Radiologic investigation revealed large polycystic tumors on both ovaries. Bilateral ovariectomy was performed and microscopic examination showed mucinous ovarian tumors. The authors discuss the increased risk for cancer in patients with the Peutz-Jeghers syndrome and review the different ovarian tumors associated with this syndrome. They also stress that these patients must be followed not only for gastrointestinal disease but also by regular gynecologic examination.

Abstract
The human LKB gene (official HUGO symbol, STK11) encodes a serine/threonine protein kinase that is defective in patients with Peutz-Jeghers syndrome (PJS). PJS is an autosomal dominantly inherited syndrome characterized by hamartomatous polyposis of the gastrointestinal tract and mucocutaneous pigmentation. To date, 145 different germline LKB1 mutations have been reported. The majority of the mutations lead to a truncated protein product. One mutational hotspot has been observed. A 1-bp deletion and a 1-bp insertion at the mononucleotide repeat (C6 repeat, c.837-c.842) between the codons 279-281 have been found in six and seven unrelated PJS families, respectively. However, these mutations account only for approximately 7% of all mutations identified in the PJS families (13/193). A review of the literature provides a total of 40 different somatic LKB1 mutations in 41 sporadic tumors and seven cancer cell lines. Mutations occur particularly in lung and colorectal cancer. Most of the somatic LKB1 mutations result in truncation of the protein. A mutational hotspot seems to be a C6 repeat accounting for 12.5% of all somatic mutations (6/48). These results are concordant with the germline mutation spectrum. However, the proportion of the missense mutations seems to be higher among the somatic mutations (45%) than among the germline mutations (21%), and only seven of the mutations are exactly the same in both of the mutation types.

Abstract
Peutz-Jeghers syndrome (PJS) is a rare disorder characterized by benign intestinal hamartomatous polyps and mucocutaneous pigmentation, and with an increased risk for intestinal and extra-intestinal neoplasms. Sertoli cell tumors in boys with PJS have been increasingly recognized as a cause of prepubertal gynecomastia. However, an association between nephrocalcinosis and PJS has not been reported before. We report on a 7.25-year-old boy with PJS, bilateral gynecomastia, Sertoli cell tumor and nephrocalcinosis, and present the outcome of 1-year treatment with the aromatase inhibitor testolactone. The patient presented with bilateral breast and testis enlargement, and mucocutaneous pigmentation. Testicular ultrasound revealed parenchymal multiple microcalcifications. Histopathological examination was consistent with Sertoli cell tumors. Nephrocalcinosis due to idiopathic renal hypercalciuria was also detected. The aromatase inhibitor testolactone was begun in an attempt to prevent acceleration in skeletal maturation. One-year treatment with testolactone reduced the breast base diameter from 7 to 3 cm, and bone age advanced 1.2 years during this period. Our case demonstrates that waiting for the effect of aromatase inhibitors on gynecomastia before making a decision for mastectomy may be a reasonable option. We also consider that the association between PJS and nephrocalcinosis may be a coincidence.

Abstract
Besides gastrointestinal hamartomatous polyposis and melanin spots in the skin and mucosa, patients with the Peutz-Jeghers syndrome (PJS) have repeatedly been observed with a variety of tumours, including lung cancer. Available data indicate an increased cancer risk among PJS patients, which suggests that the gene involved in PJS, STK11 on chromosome 19p13.3, may be a tumour suppressor gene. Herein, bronchioloalveolar carcinoma (BAC) of mucinous type is reported in a 22-year old male PJS patient with a novel germline frameshift insertion in exon 2 at codon 118 of the STK11 gene. Molecular studies of his BAC indicated loss of heterozygosity (LOH) in the region of STK11 on chromosome 19p13.3. This observation supports the hypothesis that STK11 is a tumour suppressor gene which is involved in the development of lung adenocarcinoma.

Abstract
Inherited forms of gastrointestinal cancer have been a major focus of study and advancement over the past decade. Familial adenomatous polyposis and hereditary nonpolyposis colon cancer are the two most common heritable colon cancer syndromes. Inherited polyposis syndromes are characterized by the dominant type of polyp (whether adenomatous or hamartomatous) present and by the polyp's location within the gastrointestinal tract. The hamartomatous polyposis syndromes are characterized by an overgrowth of cells native to the area in which they normally occur. They represent a small but appreciable number of the gastrointestinal inherited cancer predisposition syndromes; it is now known that many of these syndromes carry a substantial risk for developing colon cancer as well as other gastrointestinal and pancreatic cancers. Patients afflicted with these syndromes are also at significant risk for extraintestinal malignancies. Seven inherited hamartomatous polyposis syndromes have been described: familial juvenile polyposis syndrome, Cowden's syndrome, Bannayan-Ruvalcaba-Riley syndrome, Peutz-Jeghers syndrome, basal cell nevus syndrome, neurofibromatosis 1, and multiple endocrine neoplasia syndrome 2B. Hereditary mixed polyposis syndrome is a variant of juvenile polyposis characterized by both hamartomatous and adenomatous polyps. The hamartomatous syndromes occur at approximately 1/10th the frequency of the adenomatous syndromes and account for <1% of colorectal cancer in Northern America. While the diagnosis of these inherited syndromes is primarily clinical, genetic testing is now available for all six syndromes. However, there are a significant number of spontaneous mutations seen in each of the syndromes. The management of these patients necessitates a coordinated multidisciplinary approach. The purpose of this review is to characterize the clinical and pathological features of these syndromes and to review the targets of cancer surveillance. The molecular alterations responsible for the inherited hamartomatous polyposis syndromes will also be discussed.

Abstract
Germ-line mutations in the serine-threonine kinase gene STK11 (LKB1) cause Peutz-Jeghers syndrome (PJS), a rare autosomal dominantly inherited disease, characterized by hamartomatous polyposis and mucocutaneous pigmentation. STK11 mutations only account for about half of PJS cases, and a second disease locus has been proposed at chromosome segment 19q13.4 on the basis of genetic linkage analysis in one family. We identified a t(11;19)(q13;q13.4) in a PJS polyp arising from the small bowel in a female infant age 6 days. Because the breakpoint in 19q13.4 may disrupt the putative PJS disease gene mapping to this region, we mapped the breakpoint and analyzed DNA from the case and a series of STK11-negative PJS cases. Using two-color interphase fluorescence in situ hybridization, the breakpoint region was refined to a 0.5-Mb region within 19q13.4. Eight candidate genes mapping to the breakpoint region--U2AF2, EPN1, NALP4, NALP11, NALP5, ZNF444, PTPRH, and KIAA1811--were screened for mutations in germ-line and polyp DNA from the case and from 15 PJS cases that did not harbor germ-line STK11 mutations. No pathogenic mutations in the candidate genes were identified. This report provides further evidence of the existence of a second PJS disease locus at 19q13.4 and excludes involvement of eight candidate genes.

Abstract
We analyzed 72 patients with ovarian sex cord-stromal tumors (OSCST) registered at the German Pediatric Tumor Registry in Kiel over a 20-year period. Juvenile granulosa cell tumors (JGCT, n=48) were the most frequent histological subtype. In addition, there were 14 Sertoli-Leydig cell tumors, 5 sclerosing stromal tumors, 2 sex cord tumors with annular tubules, 2 thecomas and 1 steroid cell tumor. Stage according to FIGO (International Federation of Gynecologists and Obstetricians) was Ia in 39 patients, Ic in 17 patients, II in 3 patients and III in 1 patient (60 patients with complete data). Compared with adult granulosa cell tumors, JGCT showed pronounced mitotic activity [mean 9.8 mitoses/10 high power field (HPF)], which was significantly higher than in other histological subtypes (2.7/10 HPF, P=0.001). Immunohistochemical analysis revealed frequent coexpression of vimentin (positive in 52/52 examined tumors), cytokeratin (27/33), and inhibin (19/20). Of patients, 12 with Ic or higher stage tumors received adjuvant cisplatinum-based chemotherapy. Event-free survival at 10 years was 0.88 +/- 0.05 (38/43 patients with follow-up data). Outcome significantly correlated with stage and mitotic activity (<20 versus > or =20 mitoses/10 HPF: event-free survival 1.0 versus 0.48 +/- 0.05, P=0.0001). In conclusion, this analysis confirms that the majority of patients with OSCST present at low tumor stage and that prognosis in these patients is excellent. Refractory tumors are characterized by high proliferative activity. Therefore, histopathological evaluation substantially contributes to risk assessment in patients with OSCST and might be useful for therapy stratification in prospective therapeutic protocols.

Abstract
Germline mutations in the LKB1/STK11 tumour suppressor gene cause Peutz-Jeghers syndrome (PJS), a rare dominant disorder. In addition to typical hamartomatous gastrointestinal polyps and pigmented perioral lesions, PJS is associated with an increased risk of tumours at multiple sites. Follow-up information on carriers is limited and genetic heterogeneity makes counselling and management in PJS difficult. Here we report the analysis of the LKB1/STK11 locus in a series of 33 PJS families, and estimation of cancer risks in carriers and noncarriers. Germline mutations of LKB1/STK11 were identified in 52% of cases. This observation reinforces the hypothesis of a second PJS locus. In carriers of LKB1/STK11 mutations, the risk of cancer was markedly elevated. The risk of developing any cancer in carriers by age 65 years was 47% (95% CI: 27-73%) with elevated risks of both gastrointestinal and breast cancer. PJS with germline mutations in LKB1/STK11 are at a very high relative and absolute risk of multiple gastrointestinal and nongastrointestinal cancers. To obtain precise estimates of risk associated with PJS requires further studies of genotype-phenotype especially with respect to LKB1/STK11 negative cases, as this group is likely to be heterogeneous.

Abstract
Despite the relatively high prevalence of ovarian cancer (1% of American women will develop this disease in their lifetime) and recent developments in its molecular genetic understanding (several proto-oncogenes, such as AKT2 and cKRAS, and tumor suppressor genes, such as BRCA1 and BRCA2, have been implicated), little is known about the presence of ovarian tumors and cancer in women already diagnosed with other familial multiple tumor syndromes. In this review, we focus on the possible association of ovarian tumors with multiple endocrine neoplasias (MENs) and their related syndromes, such as Carney complex (CNC), Peutz-Jeghers syndrome (PJS), von Hippel-Lindau disease (VHLD), and Cowden's disease (CD). These conditions recently have been molecularly elucidated, and some of the genes responsible for them (including STK11/LKB1 and PTEN, the genes responsible for PJS and CD, respectively) have already been investigated in series of sporadic ovarian lesions, mostly carcinomas. A brief description of each disease is followed by a literature search for affected patients with ovarian tumors; we review our own experience with CNC patients and ovarian tumors. An association between PJS and CNC and ovarian neoplasms seems likely; carcinoids of the ovary may occur in patients with MEN 1. Only few patients with CD and VHLD have any ovarian pathology, but PTEN, the CD gene has been investigated in sporadic ovarian tumors. The aim of the present report is to alert clinicians who care for patients with MENs, CNC, PJS, VHLD, CD, and other syndromes for possible associations between various types of ovarian tumors and these conditions.

Abstract
Small intestinal neoplasms are uncommonly encountered in clinical practice. They may occur sporadically, in association with genetic diseases (e.g., familial adenomatous polyposis coli or Peutz-Jeghers syndrome), or in association with chronic intestinal inflammatory disorders (e.g., Crohn's disease or celiac sprue). Benign small intestinal tumors (e.g., leiomyoma, lipoma, hamartoma, or desmoid tumor) usually are asymptomatic but may present with intussusception. Primary malignancies of the small intestine-including adenocarcinoma, leiomyosarcoma, carcinoid, and lymphoma-may present with intestinal obstruction, jaundice, bleeding, or pain. Extraintestinal neoplasms may involve the intestine via contiguous spread or peritoneal metastasis. Hematogenous metastases to the intestine from an extraintestinal primary are unusual and are most typical of melanoma. Because the small intestine is relatively inaccessible to routine endoscopy, diagnosis of small intestinal neoplasms is often delayed for months after onset of symptoms. When the diagnosis is suspected, enteroclysis is the most useful imaging study. Small bowel endoscopy (enteroscopy) is increasingly widely available and may permit earlier, nonoperative diagnosis.

Abstract
The list of multiple endocrine neoplasias (MENs) that have been molecularly elucidated is growing with the most recent addition of Carney complex. MEN type 1 (MEN 1), which affects primarily the pituitary, pancreas, and parathyroid glands, is caused by mutations in the menin gene. MEN type 2 (MEN 2) syndromes, MEN 2A and MEN 2B that affect mainly the thyroid and parathyroid glands and the adrenal medulla, and familial medullary thyroid carcinoma (FMTC), are caused by mutations in the REToncogene. Finally, Carney complex, which affects the adrenal cortex, the pituitary and thyroid glands, and the gonads, is caused by mutations in the gene that codes for regulatory subunit type 1A of protein kinase A (PKA) (PRKAR1A) in at least half of the known patients. Molecular defects have also been identified in syndromes related to the MENs, like Peutz-Jeghers syndrome (PJS) (the STK11/LKB1 gene), and Cowden (CD; the PTEN gene) and von Hippel-Lindau disease (VHLD; the VHL gene). Although recognition of these syndromes at a young age generally improves prognosis, the need for molecular testing in the diagnostic evaluation of the MENs is less clear. This review presents the newest information on the clinical and molecular genetics of the MENs (MEN 1, MEN 2, and Carney complex), including recommendations for genetic screening, and discusses briefly the related syndromes PJS, CD and VHLD.

Abstract
This chapter deals with pre-malignant epithelial lesions of the gastrointestinal tract that have the potential to become cancers. Pre-malignant lesions are divided into two types: those characterized by dysplastic mucosa and those without dysplasia. Examples of the two types are present in the oesophagus, stomach and intestine. In the oesophagus, dysplasia of the squamous epithelium is a precursor to squamous carcinoma. There are differences in interpretation between Western and Japanese pathologists in the diagnosis of oesophageal squamous lesions. Dysplasia in Barrett's oesophagus is regarded as a precursor of adenocarcinoma. The goal of endoscopic surveillance in Barrett's mucosa is the detection of high-grade dysplasia. There are several problems with our current knowledge of high-grade dysplasia and controversies regarding its management. There are differences in the interpretation of biopsies of gastric epithelial dysplasia between Japanese and Western pathologists. In the colon, pre-malignant lesions include dysplasia seen in inflammatory bowel disease and colonic adenomas. The most significant predictor of the risk of malignancy in patients with inflammatory bowel disease is the presence of dysplasia in colonic biopsies. Because of the similarity of neoplasia throughout the gastrointestinal tract, there have been attempts to unify its classification, terminology and diagnostic criteria internationally, the most recently proposed modified classification of gastrointestinal neoplasia being the Vienna classification. Dysplasia of the columnar mucosa has a similar appearance in Barrett's oesophagus, the stomach and the colon. Criteria for its histological diagnosis and grading are reviewed, with an emphasis on areas of diagnostic difficulty such as interobserver variation, and discrepancies between Western and Japanese pathologists. Implication of the presence of dysplasia that are specific to each organ site are discussed, highlighting weaknesses and controversies in current knowledge.

Abstract
UNLABELLED The Peutz-Jeghers syndrome is a hereditary disease that requires frequent endoscopic and surgical intervention, leading to secondary complications such as short bowel syndrome. CASE REPORT This paper reports on a 15-year-old male patient with a family history of the disease, who underwent surgery for treatment of an intestinal occlusion due to a small intestine intussusception. DISCUSSION An intra-operative fiberscopic procedure was included for the detection and treatment of numerous polyps distributed along the small intestine. Enterotomy was performed to treat only the larger polyps, therefore limiting the intestinal resection to smaller segments. The postoperative follow-up was uneventful. CONCLUSION We point out the importance of conservative treatment for patients with this syndrome, especially those who will undergo repeated surgical interventions because of clinical manifestation while they are still young.
