Cowden Syndrome breast, endometrial, and thyroid cancer. SYNONYMS, multiple hamartoma syndrome. PATHOGENESIS, CHARACTERIZATION. Identification of a PTEN http://www.thedoctorsdoctor.com/diseases/cowdensyndrome.htm
Extractions: Background Cowden syndrome (CS) is a autosomal dominant inherited syndrome. These patients are characterized by multiple hamartomas occurring in the skin, breast, thyroid, gastrointestinal tract, endometrium, and brain. Patients do have an increased risk of experiencing malignant tumors with the most common ones are breast, endometrial, and thyroid cancer. SYNONYMS Multiple hamartoma syndrome PATHOGENESIS CHARACTERIZATION Identification of a PTEN mutation in a family with Cowden syndrome and Bannayan-Zonana syndrome J Am Acad Dermatol 2001;44:183-7 Single kindred with individuals manifesting both CS and BZS phenotypes (CS/BZS overlap family) Novel mutation in PTEN by DNA sequencing. The PTEN gene (phosphatase and tensin homolog deleted from chromosome 10) has been identified as the susceptibility gene for CS and BZS Also known as MMAC1 (mutated in multiple advanced cancers) or TEP1 (TGF-regulated and e pithelial cell-enriched p hosphatase), is a tumor suppressor gene located on chromosome 10q23.28-30 It has 9 exons that encode a protein of 403 amino acids. The presence of individuals with CS and BZS within the same family, and moreover the identification of identical PTEN gene mutations in these individuals, suggest that these two syndromes represent different phenotypic expressions of one disease

Extractions: Last Revised: April 2002 Other Names The use of different names can be confusing. The problem started when several different groups of physicians and researchers began describing collections of features they observed in their patients. Each group believed that they were describing a new condition. Because CS consists of various features that occur at different times or not at all, the names became even more confused. Simply put, different people will show different features even though they have the same genetic condition. That was enough to make researchers at the time believe they were describing different conditions. In fact, scientists did not realize that all these names were describing one condition until 1986 when it was proposed that Bannayan syndrome and Ruvalcaba-Myhre syndrome were one and the same. In 1996, the overlap of features in CS and Bannayan-Riley-Ruvalcaba syndrome was recognized and molecular evidence for this observation was reported in 1997 and 1999. Since then, many names have been added to the list of syndromes. Below are several names that you may encounter as well. Bannayan-Zonana syndrome Riley-Smith syndrome Ruvalcaba-Myhre syndrome

It is associated with the increased risk of colorectal cancer. Ataxia-Telangiectasia : This inherited disorder affects many multiple systems in the body, including progressive degeneration of the cerebellum, a part of the brain, the appearance of spider veins, immunodeficiency that leads to recurrent respiratory infections, and a predisposition to cancer. It may include cancer of the brain, breast, leukemia, lymphoma, skin, stomach and uterus. Basal Cell Nevus Syndrome Bloom Syndrome : An inherited disorder characterized by short height, a sun-sensitive redness on the face, susceptibility to infections, and a tendency to develop several types of cancers, including breast, cervix, colon, esophagus, larynx, lung, skin, and tongue cancers, and leukemia and lymphoma. : A mutation prevents this gene from producing a tumor suppression protein which controls cell growth. This gene was discovered in 1995 and is linked to breast and pancreatic cancer, and possibly colon and prostate cancer.

TRICHILEMMOMA Cowden s syndrome (multiple hamartoma syndrome) is an autosomal dominant disease characterized by multiple cutaneous hamartoma (trichilemmoma, fibroma http://www.geocities.com/sampyroy2000/T.html
Extractions: Histologically trichilemmoma is a symmetrical tumour with well circumscribed margin resting on PAS positive thickened basement membrane.The tumour is composed of glycogenated clear epithelial cells with peripheral palisading in deeper parts. These cells are PAS diastase positive. Some lesions contain eosinophilic "intermediate cells" (some times known as follicular poroma).The architectural patterns ranges from follicle like,vertically orientated , bulbous, lobular, verrucous or acrospiroma like. In many cases there is broad connection with overlying surface epithelium .Some trichilemmomas display connection with individual hair follicle. This is a variant of trichilemmoma characterized by extensive stromal component together with complex strands of clear epithelial cell in the periphery. Stroma is also present in the centre of epithelial nodules. Eosinophilic, amorphous alcian blue and PAS diastase positive material may be present (basement membrane material). CD34 positive cells are identified in trichilemmoma. The stroma contains vimentin positive cells.

Extractions: Cutaneous Markers of Internal Malignancy http://www.medicad.com I. Direct tumour spread: The skin is a relatively uncommon site for metastatic deposits compared to organs such as liver, lung and bone. The most common sources of cutaneous metastases are lung, breast and colon. Renal and thyroid skin deposits may be vascular and are occasionally misdiagnosed as benign haemangiomas. Direct invasion of the skin: The most frequent cause is carcinoma of the breast either as skin ulceration, Paget's disease, carcinoma erysipeloides, or carcinoma en cuirasse. Squamous-cell carcinoma of the oral cavity also may ulcerate onto the face. Paget's disease of the breast is an epidermal manifestation of an underlying ductal adenocarcinoma. Extramammary Paget's, e.g. in anogenital area may be a marker of underlying neoplasia such as adenocarcinoma of the rectum. Specific cutaneous infiltrations may occur with lymphoma and leukaemia II.

Leesiot käsittävät papuloita, jotka voivat olle pieniä ja lukuisia tai papillomatoottisia ja syylämäisiä muodostelmia, jotka usein yhdistyvät ja peittävät laajoja alueita suun limakalvoa ja saavat limakalvon näyttämään "mukulakivimäiseltä". Suun limakalvon papillomatoosi käsittää pääasiassa sileäpintasia papuloita, jotka ovat ikenissä, kielessä, huulessa, uvulassa ja suulaessa.
