|
|
|
Submandibular gland
|
mixed- mucinous and granular basophilic
|
|
|
Most salivary gland tumors arise from
|
parotid glands- vast majority are benign.
|
|
|
Pleimorphic adenoma
|
most common benign tumor of salivary gland parotid and submandibular.
Solid tumors with smooth edges and abundant myxoid EC material treatment = surgical excision |
|
|
Warthins Tumor
|
benign mixed tumor usu parotid gland tumor, and usu bilateral and in elderly men. cavitary structure within which you have polypoid projections. on palpation they feel softer. two major cell types- epithelium-neoplastic and lymphocytes(non neoplastic) reactive
treatment = NOTHING |
|
|
Adenoid cystic carcinoma
|
second most common, more common in submandibular than salivary
|
|
|
Sjogren's Syndrome
|
Xerostomia & Keratoconjunctivitis Sicca (corneal damage) from immunologically – mediated damage to salivary & lacrimal glands
90% middle aged or older women *Bilateral parotid enlargement (Mikulicz’s) SS-A & SS-B; RF; ANAs Periductal & perivascular lymphocytic (CD4) infiltrates Degenerative & hyperplastic ductal changes Acinar atrophy; fibrosis & fat |
|
|
Mucoepidermoid carcinoma
|
most common neoplastic salivary gland tumor. Squamous and adenocarcinoma.
treatment = parotidectomy |
|
|
Complications of parotidectomy |
•CN7 injury •Frey’sSyndrome (gustatory sweating) •Sialocele •Earnumbness (which nerve?)•Infection/Bleeding(hematoma) |
