Cowden syndrome
(重定向自Cowden disease)

Cowden syndrome (also known as "Cowden's disease," and "Multiple hamartoma syndrome") is a rare autosomal dominant inherited disorder characterized by multiple non-cancerous tumor-like growths called hamartomas, which typically are found in the skin, mucous membranes (mouth, nasal membranes, GI tract), thyroid gland, and breast tissue. While the hamartomas are benign, people with Cowden Syndrome are at increased risk of certain forms of cancer, including breast, thyroid, uterus (endometrial), and kidney cancers.
