Salivary Gland Neoplasms: Tumors or cancer of the SALIVARY GLANDS.Salivary Glands: Glands that secrete SALIVA in the MOUTH. There are three pairs of salivary glands (PAROTID GLAND; SUBLINGUAL GLAND; SUBMANDIBULAR GLAND).Adenoma, 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)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)Parotid Neoplasms: Tumors or cancer of the PAROTID GLAND.Salivary Glands, Minor: Accessory salivary glands located in the lip, cheek, tongue, floor of mouth, palate and intramaxillary.Palatal Neoplasms: Tumors or cancer of the PALATE, including those of the hard palate, soft palate and UVULA.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)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.Sebaceous Gland NeoplasmsAnal Gland Neoplasms: Tumors or cancer of the anal gland.Salivary Gland DiseasesSubmandibular 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)Sublingual Gland Neoplasms: Neoplasms of the sublingual glands.Perianal GlandsSubmandibular Gland NeoplasmsParotid 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.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.Sublingual Gland: A salivary gland on each side of the mouth below the TONGUE.Salivary Ducts: Any of the ducts which transport saliva. Salivary ducts include the parotid duct, the major and minor sublingual ducts, and the submandibular duct.Sjogren's Syndrome: Chronic inflammatory and autoimmune disease in which the salivary and lacrimal glands undergo progressive destruction by lymphocytes and plasma cells resulting in decreased production of saliva and tears. The primary form, often called sicca syndrome, involves both KERATOCONJUNCTIVITIS SICCA and XEROSTOMIA. The secondary form includes, in addition, the presence of a connective tissue disease, usually rheumatoid arthritis.Sialadenitis: INFLAMMATION of salivary tissue (SALIVARY GLANDS), usually due to INFECTION or injuries.Exocrine Glands: Glands of external secretion that release its secretions to the body's cavities, organs, or surface, through a duct.Salivary Gland Calculi: Calculi occurring in a salivary gland. Most salivary gland calculi occur in the submandibular gland, but can also occur in the parotid gland and in the sublingual and minor salivary glands.Mammary Glands, Animal: MAMMARY GLANDS in the non-human MAMMALS.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.Submandibular Gland DiseasesSweat Gland NeoplasmsSalivation: The discharge of saliva from the SALIVARY GLANDS that keeps the mouth tissues moist and aids in digestion.Endocrine Gland Neoplasms: Tumors or cancer of the ENDOCRINE GLANDS.Xerostomia: Decreased salivary flow.Immunohistochemistry: Histochemical localization of immunoreactive substances using labeled antibodies as reagents.Saliva: The clear, viscous fluid secreted by the SALIVARY GLANDS and mucous glands of the mouth. It contains MUCINS, water, organic salts, and ptylin.Sweat Glands: Sweat-producing structures that are embedded in the DERMIS. Each gland consists of a single tube, a coiled body, and a superficial duct.Sebaceous Glands: Small, sacculated organs found within the DERMIS. Each gland has a single duct that emerges from a cluster of oval alveoli. Each alveolus consists of a transparent BASEMENT MEMBRANE enclosing epithelial cells. The ducts from most sebaceous glands open into a HAIR FOLLICLE, but some open on the general surface of the SKIN. Sebaceous glands secrete SEBUM.Lacrimal Apparatus: The tear-forming and tear-conducting system which includes the lacrimal glands, eyelid margins, conjunctival sac, and the tear drainage system.Harderian Gland: A sebaceous gland that, in some animals, acts as an accessory to the lacrimal gland. The harderian gland excretes fluid that facilitates movement of the third eyelid.Diptera: An order of the class Insecta. Wings, when present, number two and distinguish Diptera from other so-called flies, while the halteres, or reduced hindwings, separate Diptera from other insects with one pair of wings. The order includes the families Calliphoridae, Oestridae, Phoridae, SARCOPHAGIDAE, Scatophagidae, Sciaridae, SIMULIIDAE, Tabanidae, Therevidae, Trypetidae, CERATOPOGONIDAE; CHIRONOMIDAE; CULICIDAE; DROSOPHILIDAE; GLOSSINIDAE; MUSCIDAE; TEPHRITIDAE; and PSYCHODIDAE. The larval form of Diptera species are called maggots (see LARVA).Adrenal Glands: A pair of glands located at the cranial pole of each of the two KIDNEYS. Each adrenal gland is composed of two distinct endocrine tissues with separate embryonic origins, the ADRENAL CORTEX producing STEROIDS and the ADRENAL MEDULLA producing NEUROTRANSMITTERS.Aquaporin 5: Aquaporin 5 is a water-specific channel protein that is expressed primarily in alveolar, tracheal, and upper bronchial EPITHELIUM. It plays an important role in maintaining water HOMEOSTASIS in the LUNGS and may also regulate release of SALIVA and TEARS in the SALIVARY GLANDS and the LACRIMAL GLAND.Sialography: Radiography of the SALIVARY GLANDS or ducts following injection of contrast medium.Insect Proteins: Proteins found in any species of insect.Carcinoma, Acinar Cell: A malignant tumor arising from secreting cells of a racemose gland, particularly the salivary glands. Racemose (Latin racemosus, full of clusters) refers, as does acinar (Latin acinus, grape), to small saclike dilatations in various glands. Acinar cell carcinomas are usually well differentiated and account for about 13% of the cancers arising in the parotid gland. Lymph node metastasis occurs in about 16% of cases. Local recurrences and distant metastases many years after treatment are common. This tumor appears in all age groups and is most common in women. (Stedman, 25th ed; Holland et al., Cancer Medicine, 3d ed, p1240; from DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p575)Parotid DiseasesLip: Either of the two fleshy, full-blooded margins of the mouth.Sodium Pertechnetate Tc 99m: A gamma-emitting radionuclide imaging agent used for the diagnosis of diseases in many tissues, particularly in the gastrointestinal system, cardiovascular and cerebral circulation, brain, thyroid, and joints.Parathyroid Glands: Two pairs of small oval-shaped glands located in the front and the base of the NECK and adjacent to the two lobes of THYROID GLAND. They secrete PARATHYROID HORMONE that regulates the balance of CALCIUM; PHOSPHORUS; and MAGNESIUM in the body.Meibomian Glands: The sebaceous glands situated on the inner surface of the eyelids between the tarsal plates and CONJUNCTIVA.Chironomidae: A family of nonbiting midges, in the order DIPTERA. Salivary glands of the genus Chironomus are used in studies of cellular genetics and biochemistry.Brunner Glands: The abundant submucosal mucous glands in the DUODENUM. These glands secrete BICARBONATE IONS; GLYCOPROTEINS; and PEPSINOGEN II.Adrenal Gland Neoplasms: Tumors or cancer of the ADRENAL GLANDS.Pancreatic Neoplasms: Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).Scent Glands: Exocrine glands in animals which secrete scents which either repel or attract other animals, e.g. perianal glands of skunks, anal glands of weasels, musk glands of foxes, ventral glands of wood rats, and dorsal glands of peccaries.

... is the most common type of minor salivary gland malignancy in adults. Mucoepidermoid carcinoma can also be found in other organs, such as bronchi, lacrimal sac and thyroid. Mucicarmine staining is one stain used by pathologist for detection. Occurs in adults, with peak incidence from 20-40 years of age. A causal link with cytomegalovirus (CMV) has been strongly implicated in a 2011 research. Presents as painless, slow-growing mass that is firm or hard. Most appear clinically as mixed tumors. This tumor is not encapsulated and is characterized by squamous cells, mucus-secreting cells, and intermediate cells. Mucoepidermoid carcinomas of the salivary and bronchial glands are characterized by a recurrent t(11;19)(q21;p13) chromosomal translocation resulting in a MECT1-MAML2 fusion gene. The CREB-binding domain of the CREB coactivator MECT1 (also known as CRTC1, TORC1 or WAMTP1) is fused to the ...

... is a common benign salivary gland neoplasm characterised by neoplastic proliferation of parenchymatous glandular cells along with myoepithelial components, having a malignant potentiality. It is the most common type of salivary gland tumor and the most common tumor of the parotid gland. It derives its name from the architectural Pleomorphism (variable appearance) seen by light microscopy. It is also known as "Mixed tumor, salivary gland type", which describes its pleomorphic appearance as opposed to its dual origin from epithelial and myoepithelial elements. The tumor is usually solitary and presents as a slow growing, painless, firm single nodular mass. Isolated nodules are generally outgrowths of the main nodule rather than a multinodular presentation. It is usually mobile unless found in the palate and can cause ...
... is a type of benign salivary gland tumor that occurs most often in minor salivary glands. In addition to pleomorphic adenoma, the two are the most common tumors of the upper lip. In 95% of cases, canalicular adenoma occurs on the upper lip. The next most common location is the buccal mucosa (inner cheek). Other sites of the mouth, including the parotid gland, are rare for this disease. Canalicular adenoma is most likely to occur in older adults around 70 years of age. There is a predilection for gender with most cases being in females. Canalicular adenoma is characterized as a slow growing, painless swelling, whose diameter can be up to 2 cm. It can be normal or bluish in color. The appearance of this tumor microscopically is very distinct. There are cords of columnar or cuboidal epithelium, which have basophillic nuclei. Parallel rows of cords appear to form long canals. Frequently, ...
... primarily affects older individuals (age 60-70 years). There is a slight male predilection according to recent studies. The tumor is slow growing, painless, and usually appears in the tail of the parotid gland near the angle of the mandible. In 5-14% of cases, Warthin's tumor is bilateral, but the two masses usually are at different times. Warthin's tumor is highly unlikely to become malignant. ...
... is a benign tumour of the salivary gland. Sebaceous lymphadenoma is a tissue diagnosis, e.g. salivary gland biopsy. It may be confused with a number of benign and malignant neoplasms, including Warthin tumour, mucoepidermoid carcinoma and sebaceous lymphadenocarcinoma. The treatment is simple excision and exclusion of a malignant neoplasm. Lymph node Lymphoma Salivary gland neoplasm Mishra, A.; Tripathi, K.; Mohanty, L.; Nayak, M.

... (commonly referred to as Sialendoscopy) is a minimally invasive technique that allows for salivary gland surgery for the safe and effective treatment of obstructive salivary gland disorders and other conditions of the salivary glands. During sialoendoscopy a small endoscope is placed into the salivary glands through the salivary ducts that empty into the mouth. Sialoendoscopy is an efficient yet simple mode of treatment for major salivary gland obstructions, strictures and sialoliths (salivary stones). Depending on the obstruction, sialoendoscopy can be conducted under local anesthesia in an outpatient office or in the operating room under general anesthesia. ...
... is a malignant neoplasm derived from ceruminous glands of the external auditory canal. This tumor is rare, with several names used in the past. Synonyms have included cylindroma, ceruminoma, ceruminous adenocarcinoma, not otherwise specified (NOS), ceruminous adenoid cystic carcinoma (ACC), and ceruminous mucoepidermoid carcinoma. This tumor only affects the outer 1/3 to 1/2 of the external auditory canal as a primary site. If this area is not involved, the diagnosis should be questioned. The most common tumor type is ceruminous adenoid cystic carcinoma and ceruminous adenocarcinoma, NOS. Pain is the most common symptom, followed by either sensorineural or conductive hearing loss, tinnitus or drainage (discharge). A mass lesion may be present, but it is often slow growing. Imaging studies are used to define the extent of the tumor and to exclude direct extension from the parotid gland or nasopharynx. The imaging findings are usually non-specific, and cannot give a ...
The serous fluid contains the enzyme amylase which acts in the digestion of carbohydrates. Minor salivary glands on the tongue secrete the amylase. The parotid gland produces purely serous saliva. The other major salivary glands produce mixed (serous and mucus) saliva. Another type of serous fluid is secreted by the two layered serous membranes which line the body cavities. The serous fluid between the two layers acts as a lubricant and reduces friction from muscle movement. ...

... s are glands that produce and secrete substances onto an epithelial surface by way of a duct. Examples of exocrine glands include sweat, salivary, mammary, ceruminous, lacrimal, sebaceous, and mucous. Exocrine glands are one of two types of glands in the human body, the other being endocrine glands, which secrete their products directly into the bloodstream. The liver and pancreas are both exocrine and endocrine glands; they are exocrine glands because they secrete products-bile and pancreatic juice-into the gastrointestinal tract through a series of ducts, and endocrine because they secrete other substances directly into the bloodstream. Exocrine glands contain a glandular portion and a duct portion, the structures of which can be used to classify the gland. The duct portion may be branched (called ...
The location of the Skene's glands are the general area of the vulva, located on the anterior wall of the vagina around the lower end of the urethra. The Skene's glands are homologous with the prostate gland in males, containing numerous microanatomical structures in common with the prostate gland, such as secretory cells.[2][3] Skene's glands are not, however, explicit prostate glands themselves. The two Skene's ducts lead from the Skene's glands to the surface of the vulva, to the left and right of the urethral opening from which they are structurally capable of secreting fluid.[2] Although there remains debate about the function of the Skene's glands, one purpose is to secrete a fluid that helps lubricate the urethral opening, possibly contributing antimicrobial factors to protect the urinary tract from infections.[3]. The source of female ejaculation has not been ...
