In women who were exposed to certain chemicals, vaginal adenosis may arise in up to 90%. Since these contraceptives were discontinued, incidence has dropped dramatically. [4] Risk is however still present in subsequent generations due to recent exposure. [5] It is thought steroid hormones play a stimulatory growth in adenosis formation. [6]
Sclerosing polycystic adenosis (also abbreviated SPA) is a rare salivary gland tumor first described in 1996 by Dr. Brion Smith. [1] The major salivary glands, specifically the parotid gland (about 70% of cases) and the submandibular gland , are affected most commonly.
Adenosis involves an abnormal count and density of lobular units, while other lesions appear to mainly arise from ductal epithelial origins. There is evidence that iodine deficiency contributes to fibrocystic breast changes by enhancing breast tissue sensitivity to estrogen .
Chronic sclerosing sialadenitis is a chronic (long-lasting) inflammatory condition affecting the salivary gland.Relatively rare in occurrence, this condition is benign, but presents as hard, indurated and enlarged masses that are clinically indistinguishable from salivary gland neoplasms or tumors.
Due to the strong association with denture-wearing, the lesion tends to occur more in adults than children. There is no gender predilection. [1] In people who wear dentures 24 hours a day, its incidence is around 20%. Inflammatory papillary hyperplasia almost exclusively involves the hard palate, specifically the vault of the palate.
Clear cell adenocarcinoma of the vagina is a rare cancer that is related to DES exposure in utero. DES was a drug previously given to some women with high-risk pregnancies to prevent miscarriage. Women who were exposed to DES in utero should be evaluated yearly with a pap smear and pelvic exam due to risk of developing clear cell adenocarcinoma.
Idiopathic osteosclerosis, also known as enostosis or dense bone island, is a condition which may be found around the roots of a tooth, usually a premolar or molar. [2] It is usually painless and found during routine radiographs as an amorphous radiopaque (light) area around a tooth.
In cases due to viral infection symptoms usually recede spontaneously after 48 hours, symptoms of bacterial adenoiditis typically persist up to a week. Adenoiditis is sometimes accompanied by tonsillitis. Repeated adenoiditis may lead to enlarged adenoids.
