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.

Symptoms may worsen during certain parts of the menstrual cycle due to hormonal stimulation. [1] These are normal breast changes, not associated with cancer. [2] Risk factors include an early age at first menstrual period and either having children at a late age or not at all. [2] It is not a disease but represents normal breast changes. [3]
There are two features relatively inconsistent with diagnosis of IgG4-related disease which are the presence of epithelioid cell granulomas and a prominent neutrophilic infiltrate. [11] Sclerosing polycystic sialadenitis histologically resembles sclerosing adenosis/fibrocystic change of breast tissue. It composes of acini and ductal elements ...
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.
Vaginal adenosis is a benign abnormality in the vagina, commonly thought to be caused by intrauterine and neonatal exposure of diethylstilbestrol and other progestogens and nonsteroidal estrogens, however it has also been observed in otherwise healthy women and has been considered at times idiopathic or congenital.
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.
Rarely, a ranula may descend into the neck rather than the mouth (plunging ranula). If small, the ranula may be left alone; if it is larger and causing symptoms, excision of the sublingual gland may be indicated. Nicotinic stomatitis is whitening of the hard palate by hyperkeratosis caused by the heat from smoking or from drinking hot liquids ...
