Cowden syndrome is considered a PTEN hamartoma tumor syndrome (PHTS), which also includes Bannayan-Riley-Ruvalcaba syndrome, Proteus syndrome and Proteus-like syndrome

PTEN hamartoma tumor syndrome is a genetic condition in which non-cancerous growths, called hamartomas, develop in different areas of the body. In addition to hamartomas, patients can have other physical findings, including larger-than-average head size, abnormal skin growths, and intellectual disabilities

some ten (PTEN) hamartoma tumor syndrome has a high rate of colonic polyposis. In contrast with prior dogma, the majority of patients will have mixed polyp histologies including adenoma, hamartoma and hyper-plastic. Thus, multiple polyp types should spur investi-gation for this syndrome with a thorough clinical exam and possibly genetic testing Genetic testing for PTEN may be considered medically necessary to confirm the diagnosis when a patient has clinical signs of a PTEN hamartoma tumor syndrome. Targeted genetic testing for a PTEN familial variant may be considered medically necessary in a first-degree rela-tive of a proband with a known PTEN pathogenic variant The PTEN Hamartoma Tumor Syndrome Foundation was founded to find treatments or therapies for PTEN Syndromes by funding research, providing PHTS education, su.. Germline mutations in the human phosphatase and tensin homolog (PTEN) gene cause a collection of rare syndromes collectively known as PTEN hamartoma tumor syndrome (PHTS; ref. 1).The best-described syndrome within PHTS is Cowden's disease (), where PTEN mutations have been identified in more than 80% of patients (1, 3).Clinical presentation of Cowden's disease is complex, like other PHTS.

Participants included patients with PTEN hamartoma tumor syndrome (PHTS) (n = 481), molecularly defined as carrying germline pathogenic PTEN mutations.

PTEN. hamartoma tumor syndrome (PHTS), a heterogeneous spectrum of disorders ranging from autism spectrum disorder (ASD) and brain patterning defects (Lhermitte-Duclos disease) to cancer predisposition syndromes (Cowden syndrome) (Hollander et al., 2011; Kurek et al., 2012a; Pilarski et al., 2011) The PTEN Hamartoma Tumor Syndrome Foundation has designated Cleveland Clinic as one of only three PTEN Clinical Centers of Excellence in the United States. Cleveland Clinic's PTEN Multidisciplinary Clinic provides clinical services and support for children and adults with a confirmed or possible diagnosis of PTEN hamartoma tumor syndrome and other disorders within the PHTS spectrum PTEN hamartoma tumor syndrome (PHTS), which comprises CS, adult Lhermitte-Duclos disease (LDD), Bannayan-Riley-Ruvalcaba syndrome (BRRS), and Proteus-like syndrome, represents a spectrum of hamartomatous overgrowth manifestations associated with germline mutations in the PTEN gene Somatic PTEN mutation occurs in a proportion of ovarian endometrioid carcinomas. However, these cancers have seldom been reported in diseases associated with germline PTEN variants, such as Cowden syndrome (CS). The present case was a 39-year-old woman with a left ovarian carcinoma who demonstrated a germline splice variant of PTEN (c.1026 + 1G > T) following genome-wide whole exome sequencing. This test is used to detect the presence of PTEN mutations in patients with PTEN Hamartoma Tumor Syndrome (PHTS); the PHTS diagnosis includes Cowden Disease (CD)/Cowden Syndrome (CS), Bannayan-Riley-Ruvalcaba Syndrome (BRSS), Proteus Syndrome (PS), and Proteus-like syndromes

PTEN (phosphatase and tensin homolog) gene mutation is associated with a few conditions known as PTEN-related diseases, with relatively similar clinical and radiological manifestations. They include: Bannayan-Riley-Ruvalcaba; COLD syndrome. Cowden syndrome; Lhermitte-Duclos disease; Those not formally fulfilling the criteria of PTEN-related diseases are often described as PTEN hamartoma tumor. In addition to the Cowden syndrome, Bannayan-Riley-Ruvalcaba syndrome, Proteus syndrome, and Proteus-like syndrome are grouped into PTEN hamartoma tumor syndrome (PHTS). Because of associated risk of malignancy in Cowden syndrome, follow up cancer surveillance based on their accompanying phenotypic features is recommended in individuals with PTEN hamartoma tumor syndrome [ 5 ] Objective: To formally study the prevalence and histologic classification of renal cell carcinoma (RCC) in a series of patients with PTEN hamartoma tumor syndrome (PHTS). Methods: We evaluated prevalence of RCC within a prospectively-accrued series of 219 patients found to have pathogenic germline PTEN mutations Alma Hoxhaj, MD, Radboud University Medical Center, Nijmegen, Netherlands, shares the findings of a retrospective study of breast cancer surveillance in women with PTEN hamartoma tumor syndrome (PHTS), assessing the frequency, imaging features and pathology of breast lesions in women with PHTS. 64 patients were included in the study. 30.2% were diagnosed with breast cancer during the mean 5.8. PTEN is a tumor suppressor gene that classically dampens the PI3K/AKT/mTOR growth-promoting signaling cascade.PTEN dysfunction causes dysregulation of this and other pathways, resulting in overgrowth. Cowden syndrome, a hereditary cancer predisposition and overgrowth disorder, was the first Mendelian condition associated with germline PTEN mutations. . Since then, significant advances by the.

PURPOSE: To report the first case of choroidal schwannoma in a patient affected by PTEN hamartoma tumor syndrome (PHTS) and investigate the molecular involvement of the phosphatase and tensin homolog (PTEN) and neurofibromin 2 (NF2) genes in this rare intraocular tumor Other clinical syndromes that are part of the PTEN hamartoma tumor syndrome are Bannayan-Riley-Ruvalcaba syndrome (BRR; diagnosed in children), Proteus syndrome, and Proteus-like syndrome. CS is characterized by a high risk of both benign and cancerous tumors of the breast, thyroid, endometrium (uterus), colorectal, kidney, and skin

Tumor-to-tumor metastasis is a rare phenomenon, but it has been suggested to be more frequent in patients with hereditary cancer syndrome. We report an autopsy case of tumor-to-tumor metastasis in a 75-year-old male. At 6 months before his death, the patient complained of hoarseness and dysphagia, and clinical whole-body examinations revealed advanced lung adenocarcinoma (T4N2M1b, Stage IV. The PTEN hamartoma tumor syndrome (PHTS) incorporates several rare diseases that occur secondary to germline mutations within the PTEN gene. The component syndromes include Cowden syndrome and Bannayan-Riley-Ruvalcaba syndrome (BRRS), which many now consider a single entity with age-related phenotypic presentations[2-5] 81323 PTEN (phosphatase and tensin homolog) (e.g., Cowden syndrome, PTEN hamartoma tumor syndrome) gene analysis; duplication/deletion variant 81403 Molecular Pathology Procedure Level 4 81435 Hereditary colon cancer disorders (e.g., Lynch syndrome, PTEN hamartoma syndrome, Cowden syndrome, familial adenomatosi Background Cowden syndrome (CS) is associated with benign hamartomatous lesions and risks for thyroid, breast and endometrial cancers.

PTEN hamartoma tumour syndrome (PHTS) is an autosomal dominant cancer-predisposition syndrome caused by mutations in the tumour suppressor gene PTEN (OMIM #601728) on chromosome 10q23.31. PHTS encompasses two overlapping phenotypes, Cowden syndrome (CS) and Bannayan-Riley-Ruvalcaba syndrome (BRRS) Marsh et al. (1999) suggested that the spectrum of disorders caused by mutation in the PTEN gene be referred to as PTEN hamartoma tumor syndrome (PHTS). Lachlan et al. (2007) concluded that the Bannayan-Riley-Ruvalcaba syndrome and Cowden syndrome represent a single condition with variable expression and age-related penetrance, which is common in tumor-suppressor disorders, and suggested that. Cowden disease (multiple hamartoma syndrome) is associated with a mutation in the tumor suppressor gene PTEN (also termed MMAC1 or TEP1) on band 10q23.PTEN is a lipid phosphatase that removes phosphate groups from signaling molecules.
