Sublingual Gland Neoplasms: Neoplasms of the sublingual glands.Sublingual Gland: A salivary gland on each side of the mouth below the TONGUE.Salivary Gland Neoplasms: Tumors or cancer of the SALIVARY GLANDS.Ranula: A form of retention cyst of the floor of the mouth, usually due to obstruction of the ducts of the submaxillary or sublingual glands, presenting a slowly enlarging painless deep burrowing mucocele of one side of the mouth. It is also called sublingual cyst and sublingual ptyalocele.Sebaceous Gland NeoplasmsAnal Gland Neoplasms: Tumors or cancer of the anal gland.Submandibular Gland: One of two salivary glands in the neck, located in the space bound by the two bellies of the digastric muscle and the angle of the mandible. It discharges through the submandibular duct. The secretory units are predominantly serous although a few mucous alveoli, some with serous demilunes, occur. (Stedman, 25th ed)Salivary Glands: Glands that secrete SALIVA in the MOUTH. There are three pairs of salivary glands (PAROTID GLAND; SUBLINGUAL GLAND; SUBMANDIBULAR GLAND).Perianal GlandsAdenoma, Pleomorphic: A benign, slow-growing tumor, most commonly of the salivary gland, occurring as a small, painless, firm nodule, usually of the parotid gland, but also found in any major or accessory salivary gland anywhere in the oral cavity. It is most often seen in women in the fifth decade. Histologically, the tumor presents a variety of cells: cuboidal, columnar, and squamous cells, showing all forms of epithelial growth. (Dorland, 27th ed)Parotid Neoplasms: Tumors or cancer of the PAROTID GLAND.Parotid Gland: The largest of the three pairs of SALIVARY GLANDS. They lie on the sides of the FACE immediately below and in front of the EAR.Carcinoma, Mucoepidermoid: A tumor of both low- and high-grade malignancy. The low-grade grow slowly, appear in any age group, and are readily cured by excision. The high-grade behave aggressively, widely infiltrate the salivary gland and produce lymph node and distant metastases. Mucoepidermoid carcinomas account for about 21% of the malignant tumors of the parotid gland and 10% of the sublingual gland. They are the most common malignant tumor of the parotid. (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p575; Holland et al., Cancer Medicine, 3d ed, p1240)Salivary Proteins and Peptides: Proteins and peptides found in SALIVA and the SALIVARY GLANDS. Some salivary proteins such as ALPHA-AMYLASES are enzymes, but their composition varies in different individuals.Serous Membrane: A thin lining of closed cavities of the body, consisting of a single layer of squamous epithelial cells (MESOTHELIUM) resting on a thin layer of CONNECTIVE TISSUE, and covered with secreted clear fluid from blood and lymph vessels. Major serous membranes in the body include PERICARDIUM; PERITONEUM; and PLEURA.Silver Proteins: Compounds of silver and proteins used as topical anti-infective agents.Palatal Neoplasms: Tumors or cancer of the PALATE, including those of the hard palate, soft palate and UVULA.Acinar Cells: Cells lining the saclike dilatations known as acini of various glands or the lungs.Mouth, Edentulous: Total lack of teeth through disease or extraction.Chloroprene: Toxic, possibly carcinogenic, monomer of neoprene, a synthetic rubber; causes damage to skin, lungs, CNS, kidneys, liver, blood cells and fetuses. Synonym: 2-chlorobutadiene.Carcinoma, Adenoid Cystic: Carcinoma characterized by bands or cylinders of hyalinized or mucinous stroma separating or surrounded by nests or cords of small epithelial cells. When the cylinders occur within masses of epithelial cells, they give the tissue a perforated, sievelike, or cribriform appearance. Such tumors occur in the mammary glands, the mucous glands of the upper and lower respiratory tract, and the salivary glands. They are malignant but slow-growing, and tend to spread locally via the nerves. (Dorland, 27th ed)Mouth FloorMucin-5B: A gel-forming mucin that is predominantly expressed by submucosal glands of airway tissues and the SUBLINGUAL GLAND. It is one of the principal components of high molecular weight salivary mucin.Myoepithelioma: A usually benign tumor made up predominantly of myoepithelial cells.Adenolymphoma: A benign tumor characterized histologically by tall columnar epithelium within a lymphoid tissue stroma. It is usually found in the salivary glands, especially the parotid.Submandibular Gland NeoplasmsSalivary Glands, Minor: Accessory salivary glands located in the lip, cheek, tongue, floor of mouth, palate and intramaxillary.
Serous demilunePolymorphous low-grade adenocarcinoma: Polymorphous low-grade adenocarcinoma, often abbreviated PLGA, is a rare, asymptomatic, slow-growing malignant salivary gland tumor. It is most commonly found in the palate.Xanthocanace ranulaSebaceous adenoma: Sebaceous adenoma is a cutaneous condition characterized by a slow-growing tumor usually presenting as a pink, flesh-coloured, or yellow papule or nodule.James et al.Submandibular gland: The paired submandibular glands are major salivary glands located beneath the floor of the mouth. They each weigh about 15 grams and contribute some 60–67% of unstimulated saliva secretion; on stimulation their contribution decreases in proportion as the parotid secretion rises to 50%.Dredge turning gland: Dredge Turning Gland is a Trailing Suction Hopper Dredger component.Weaire–Phelan structure: In geometry, the Weaire–Phelan structure is a complex 3-dimensional structure representing an idealised foam of equal-sized bubbles. In 1993, Trinity College Dublin physicist Denis Weaire and his student Robert Phelan found that in computer simulations of foam, this structure was a better solution of the "Kelvin problem" than the previous best-known solution, the Kelvin structure..Sialoblastoma: A sialoblastoma is a low-grade salivary gland neoplasm that recapitulates primitive salivary gland anlage. It has previously been referred to as congenital basal cell adenoma, embryoma, or basaloid adenocarcinoma.Julie Campbell TathamChloropreneAdenoid cystic carcinomaDark FieldsEpithelial-myoepithelial carcinoma: Epithelial-myoepithelial carcinoma, abbreviated EMCa, is a rare malignant tumour that typically arises in a salivary gland and consists of both an epithelial and myoepithelial component.

(1/7) Acinic cell carcinoma found by recurrence of a mucous cyst in the sublingual gland.
This case report describes an acinic cell carcinoma found by a recurrence of a ranula in the sublingual gland. A 42-year-old male was admitted to the hospital of the Tokyo Dental College with a swelling in his right oral floor but without pain. The lesion was treated by windowing the same day under the diagnosis of a ranula, but the swelling appeared again at the same area eight months after the first operation. A resection was performed, and the specimen was sent to the clinical laboratory for pathological diagnosis. Proliferating serous cells were seen in part of the wall of an exudative mucous cyst. PAS staining was partially positive, and immunohistochemical staining for S-100 protein, lactoferrin, and amylase were also positive in cytoplasmic granules. This report concludes that the pathological diagnosis is beneficial in clarifying the reasons for the recurrence of a benign lesion. (+info)
(2/7) Salivary glands: report of a rare case of myoepithelial carcinoma involving tongue base treated by CO2 Laser.
Epithelial-myoepithelial carcinoma is a rare malignant tumour of the salivary glands. Herewith, the clinical evolution, anatomo-pathological characteristics and treatment adopted are described in a case occurring in the minor salivary glands of the tongue base. To our knowledge, this location has not been previously described in the literature. In fact, due to the rarity of the epithelial-myoepithelial carcinoma, there is no uniformity of data in the literature and very different therapeutic strategies have been suggested. In this report, the possibility of applying conservative surgery using CO(2) Laser is proposed. Results obtained in the case described confirm that conservative surgery is feasible in this type of neoplastic lesion of the tongue. (+info)

(6/7) Bilateral submandibular gland lymphoma in Sjogren's syndrome.
Salivary gland lymphoma is associated with Sjogren's syndrome. A case of bilateral submandibular gland and sublingual gland lymphoma, arising in Sjogren's syndrome, is presented. A lymphoma involving more than one salivary gland may occur in Sjogren's syndrome, and there is an increased risk of developing an extrasalivary lymphoma. (+info)
(7/7) Epstein-Barr virus (EBV) infection in salivary gland tumors: lytic EBV infection in nonmalignant epithelial cells surrounded by EBV-positive T-lymphoma cells.
To elucidate the association of Epstein-Barr virus (EBV) and salivary gland tumors, 114 cases of tumors of major salivary glands were investigated. EBV DNA was detected in all 6 cases of undifferentiated carcinoma and all 3 cases of T-cell lymphoma, but not in other tumor tissues. In situ hybridization studies for EBV DNA and EBV-encoded small RNA 1 (EBER1) showed specific localization of the EBV sequences to the undifferentiated carcinoma cells and T-lymphoma cells. Moreover, intense DNA signals were detected on nonneoplastic epithelial cells of T-lymphoma tissues. These epithelial cells were negative for EBER1 and expressed BZLF1, BALF2, and gp350/220 proteins associated with virus production. In contrast, nonmalignant epithelial cells surrounded by undifferentiated carcinoma cells showed no evidence of EBV infection or virus replication. These results indicate that there is an unusual association of salivary gland T-cell lymphomas with lytic EBV replication of nonmalignant epithelial cells. (+info)
