OPT Salivary

mucocele (mucus extravasation phenomenon) rupture of salivary gland duct with mucus spillage into soft tissues; most frequently in anterior and lower lip
ranula mucocele in the floor of the mouth
plunging/cervical ranula occurs when mucus dissects through mylohyoid and produces sweeping of the neck
superficial mucocele mucus accumulates right under surface epithelium and produces clear, small vesicles; common in posterior buccal mucosa and soft palate
salivary gland duct cyst (mucus duct cyst, sialocyst) epithelium-lined cavity that arises from salivary gland tissue but does not communicate with the lumen of the duct; contains watery fluid in the regions of the salivary ducts
sialolith dystrophic calcifications in salivary gland ducts, unrelated to blood calcium levels
sialadenitis inflammation of salivary glands from various causes; often Staph aureus and mumps
surgical mumps sialadenitis and enlargement in patients given atropine while NPO during surgical procedures
acute sialadenitis pain, swelling, purulence of salivary glands; usually bacterial and in parotid gland
chronic sialadenitis secondary to persistent salivary gland duct obstruction, usually from sialoliths; sialograms exhibit "sausaging" of Stensen's duct
juvenile recurrent parotitis most common salivary disorder in kids; recurring episodes of parotid swelling
cheilitis glandularis rare inflammatory disorder of labial minor salivary glands of unknown cause but probably sun damage
xerostomia subjective sensation of dry mouth, usually in females
Sjogren syndrome chronic systemic autoimmune disorder of salivary and lacrimal glands resulting in dry mouth and eyes -{primary Sjogren}- process occurs alone -{secondary Sjogren}- in conjunction with rheumatoid arthritis or lupus
sicca syndrome combination of dry mouth and eyes
benign lymphoepithelial lesion histologic pattern of Sjogren affected gland; acinar atrophy, lymphocytic infiltrate and residual ductal epithelium
epimyoepithelial islands duct cells and myoepithelial cells become hyperplastic and form these surrounded by lymphocytic infiltrate in Sjogren's
Mikulicz disease bilateral parotid and lacrimal gland enlargement due to benign lymphoepithelial lesions
Mikulicz syndrome any bilateral enlargement of parotid and lacrimal glands
Schirmer test strips of filtered paper that are placed in lower eyelid to gauge tear production
adenomatoid hyperplasia idiopathic process that affects hard and soft palates with painless, benign enlargements
necrotizing sialometaplasia secondary to ischemia of salivary tissue that leads to infarction and necrosis, 75% in posterior palate; often misdiagnosed as mucoepidermoid carcinoma but is benign and resolves in 5-6 weeks
pleomorphic adenoma (benign mixed tumor) most common salivary gland neoplasm; mixture of ductal and myoepithelial cells, painless, slow-growing, benign mass of considerable size
Warthin tumor (papillary cyst adenoma lymphomatosum) firm benign mass at tail of parotid/angle of mandible; associated with smoking
canalicular adenoma uncommon benign tumor in minor salivary glands, especially upper lip
basal cell adenoma uncommon benign neoplasm of basal cell layer of salivary gland ducts; 75% in parotid gland, most arise de novo
mucoepidermoid carcinoma most common malignant salivary gland tumor, can be in kids and mostly in parotid; can be confused with mucocele
intraosseous mucoepidermoid carcinoma uncommon malignant neoplasm from omnipotential odontogenic epithelium; develop with impacted teeth or odontogenic cysts, usually in the mandible
acinic cell carcinoma low-grade malignancy of mature-appearing serous acinar cells; can occur in kids
malignant mixed tumors malignant counterparts of benign pleomorphic adenoma with 3 patterns
carcinoma ex pleomorphic adenoma transformation of previously benign pleomorphic adenoma, usually after 15 years; a malignant mixed tumor
carcinosarcoma rare malignant mixed tumor of epithelial and stromal malignancies
metastasizing mixed tumor malignant mixed tumor that appears benign but exhibits metastasis in bones and lungs
adenoid cystic carcinoma (cylindroma) common malignancy of salivary glands with basaloid epithelial cells arranged in {cribriform/Swiss cheese pattern} and exhibits {perineurial invasion}
cribriform / Swiss cheese pattern arrangement of cells in adenoid cystic carcinoma; also exhibits {perineurial invasion)
polymorphous low-grade adenocarcinoma malignant salivary gland tumor, almost always in minor salivary glands with cells in many different patterns
salivary adenocarcinoma, NOS salivary gland carcinomas that defy existing classification scheme; 'trash bag' of unknown diagnoses
