Salivary Glands Flashcards
Extravasation of fluid into the surrounding tissue after s traumatic break into the continuity of minor salivary gland
Mucus extravasation cyst- mucocele
Common site of mucus extravasation cyst
Lower lip
Painless smooth surface may be bluish
Obstructed duct opening that cannot accomodate the exit of saliva produced leading to ductal dilation and surface swelling
Mucus retention cyst - mucocele
Ranula
Mucocele occuring floor of the mouth
Lateral to midline
Cervical ranula
Spilled nucin dissects through the myolohyoid muscle
Most common gland affected in ranula
Sublingual gland
Stone within the salivary gland
Sialolith
Sialolithiasis
Sialolith commonly occurs in
Submandibular gland
Locally destructive inflammatory condition of the SG, asymptomatic, necrotic, ulcerated area on the palate due to ischemia of minor SG, asa result of LA
Necrotizing sialometaplasia
Causative agent of mumps
Paramyxovirus
Benign asymptomatic enlargement of the SG or lacrimal gland commonly found in 50 yrs old females, infiltration of lymphocytes in myoepithelial islands
Mikulicz disease
Benign lymphoepithelial lesion
igG4 related disease
Autoimmune schronic systemic disorder results in xerostomia and keratoconjuctivitis sicca
Sjogrens syndrome
Secondary form of sjogrens syndrome
Xerostomia
Keratoconjuctivitis sicca
Autoimmune disorder - SLE rheumatoid arthritis
Sialography in sjogren syndrome
Fruit laden
Branch less
Cherry blossom appearance
Multi system disorder abnormal masses or nodules called granuloma in certain organs of the body, non tender smooth swelling if SG involved, bilateral parotid gland involved mimics sjogren syndrome
Sarcoidosis
Intraoral presentation of sarcoidosis
Submucosal mass
Granularity or ulceration
Gingiva and lips affected
Most common SG tumor
Pleomorphic adenoma
Features of pleomorphic adenoma
EO- parotid 85%
IO - post palate minor SG
Superficial lobe, swellings overlaying the mand ramus
3-4% will be malignant- CA ex pleomorphic adenoma
Basal cell adenoma locations
Parotid most common
Minor SG- upper lip and buccal mucosa
Common sites involving canalicular adenoma
Upper lip
Buccal mucosa
Involves Minor SG
Benign neoplasm in parotid gland, glandular cystic tumor lined by a bilayered - inner columnar oncocytic and outrr basal epi with lymphoid stroma
Warthins tumor
Papillary cystadenoma lymphomatosum
Swiss cheese pattern on histology
Adenoid cystic carcinoma
40-45% minor SG
Parotid and submandibular
Cribriform, tubular, solid
Perinueral invasion
Pain
Lungs bone brain involved
Most common malignant tumor
Mucoepidermoid carcinoma
Mucoepidermoid carcinoma found in
Parotid glands - asymptomatic swelling
Palate
Mucous and epidermoid cells
Polymorphous low grade adenocarcinoma
Second most common malignancy in minor SG
Palate
Lip
Buccal mucosa
Which tumor develops from eipthelial components of a preexisting pleomorphic adenoma
Malignant mixed tumors
