How common is Cowden syndrome? ... help with understanding Cowden syndrome? What is Cowden syndrome? Cowden syndrome is an inherited disorder characterized by multiple tumor-like growths (called hamartomas) and an increased risk of certain cancers. Almost everyone with this condition has hamartomas. These small, noncancerous growths are most commonly found on the skin and mucous membranes (such as the lining of the mouth and nose), but can also occur in the intestinal tract and other parts of the body. People with Cowden syndrome have an increased risk of developing several types of cancer, including cancers of the breast, thyroid, and uterus. Noncancerous breast and thyroid diseases are also common. Other signs and symptoms of Cowden syndrome can include an enlarged head; a rare, noncancerous brain tumor called Lhermitte-Duclos disease; and mental retardation. How common is Cowden syndrome?

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.

Sarah Burton, UI Health Care Joy Larsen Haidle, M.S., C.G.C., UI Health Care Heather Hampel, M.S., C.G.C., Ohio State University Charis Eng, M.D., Ph.D., Ohio State University Peer Review Status: Internally reviewed by the authors First Published: Last Revised: April 2002 Cowden syndrome is a poorly recognized and thus under-diagnosed condition characterized by multiple hamartomas and a risk of breast, thyroid, and uterine neoplasias (both benign and malignant). The most consistent features of CS, occurring in 99 percent of individuals with this clinical diagnosis, are found on the skin. These are small flesh-colored bumps on the skin involving a hair follicle (trichilemmomas) and small wart-like growths (papillomatous papules). Less commonly, CS is associated with a large head size (macrocephaly), benign fatty tumors (lipomas), and blood vessel changes (hemangiomas). The frequency of hamartomatous polyps of the small and large intestine is unknown, but is thought to occur in fewer than 40 percent of CS individuals. What is known is that CS hamartomatous polyps are rarely symptomatic. Please see Diagram 1. There is no clinical data that tells us when the features begin to appear in CS. However, we do know that more than 90 percent of individuals with CS have some features by the age of 20.

Subtle clinical and distinctive histologic features may characterize these superficial cutaneous tumors. Their significance resides in the association with Cowden disease and the need to differentiate trichilemmomas from other more aggressive cutaneous tumors. Clinically, trichilemmomas present as smooth, asymptomatic papules or verrucoid growths. They may occur as a solitary lesion or as multiple lesions, and they are usually found on the face (see Image 1 ). These lesions often mimic a basal cell carcinoma or a wart. Trichilemmoma should be considered in the differential diagnosis of any indistinct facial papule. Differentiation from a basal cell carcinoma or a trichilemmal carcinoma is needed for appropriate patient management. Trichilemmomas are often reported in association with a nevus sebaceous of Jadassohn. When many trichilemmomas are present, Cowden disease (multiple hamartoma syndrome) should be suspected. The diagnosis of trichilemmoma is usually obtained by microscopic examination, revealing distinct histologic features.

Help Cowdens Syndrome cowdenssyndrome@groups.msn.com What's New Join Now Welcome general messages ... Tools Cowden syndrome is an inhereted genetic disease. If you have it your child has a 50% chance of having it. If your parent had it you also have a 50% chance of having it. It is caused by a mutation of the Pten gene. It is inhereted equally by both sexes, although the childhood version of the disease tends to be more common in males. The Pten gene is a cell regulator gene. This means it is one of our genes that helps control cell growth. We get two copies of this gene from our parents,and if one is damaged it is harder for the body to control cell growth. Due to this problem people who have the damaged gene and have cowdens syndrome or BRRS,which is the childhood version of the disease tend to easily grow various things on their body. The most common growth in the adult and childhood version of the disease is a hamartoma. Genetics people have recently renamed both diseases to "The Pten Hamartoma Tumor Syndrome". A hamartoma is basically an overgrowth of the same tissue on where its located. A lung hamartoma is lung tissue, a breast hamartoma is breast tissue. In Cowdens Syndrome the most known risks for these hamartomas to turn cancerous are in the breast.
