Mucocele
*salivary gland gets severed releasing secretions into tissue to cause an abscess |
|
|
1) Most common salivary gland for neoplasm? 2) Most common neoplasm? 3) Most common malignant neoplasm? 4) Most common site for malignant? 5) Only tumor w/ increased incidence in males? |
1) Parotid 2) Pleomorphic Adenoma 3) Mucoepidermoid Carcinoma 4) Minor salivary glands -- but Sublingual in most common major gland effected 5) Warthins Tumor |
|
Mass in mobile and painless. What RF may he have been exposed to? |
Pleomorphic Adenoma (aka Benign Mixed tumor)
*RF = Radiation *Benign tumor of myoepithelium and ducts *Mixed = may contain cartilage and bone! |
|
Taken from Parotid. Why does this tumor reoccur? |
Pleomorphic Adenoma (aka Benign Mixed tumor)
*Pseudo-encapsulated cause incomplete ressection leading to high reoccurance *small chance of malig. trans.
|
|
|
Warthin's Tumor
*Cystic w/ papillary growths of "bilayered Onco. epi" (ie 2 layers of nuclei) separated by lymphocyte infiltrate w/ +/- germ centers *Parotid only, 2nd most common benign, 10% bilateral, only CA w/ definite link to smoking |
|
|
Mucoepidermoid Carcinoma
*mucinous adenocarcinoma (green) w/ squamous component (yellow) *Sq. part most important for prognosis *Most in partoid. Intra-oral leisons = bluish *CN7 involvement and MET to neck |
|
|
Adenoid Cystic Carcinoma
*most common malig tumor in non-parotid gland (commonly occurs as ulcer on palate) |
|
|
Adenoid Cystic Carcinoma
*Cribiform = most common histo pattern |
|
How does this tumor spread, where to, and how does this effect prognosis? |
Adenoid Cystic Carcinoma
*Perineural spread w/ infiltrative borders *Distant MET's to lung *Good short-term prog, poor long-term |
|
What may have led to this condition? |
Sialalenitis (atrophy of gland acini)
*secondary to Sialothiasis (stone in salivary gland) leading to obstruction, infxn, and inflammation |
|
|
Thyroglossal Duct Cyst
*MID-LINE dev. cyst due to epithelial remnants of tract that thyroid gland follows from foramen cecum to adult location |
|
|
Branchial Cleft Cyst
*LATERAL developmental cyst
|
|
Taken from a cervical lymph node |
Branchial Cleft Cyst
*epithelial lined cysts w/ Lymphoid tissue in cervical wall |
|
|
What is the main RF for Laryngeal CA?
What is the main RF for Laryngeal Squamous Papillary CA? |
*Laryngeal CA = tobacco and EtOH
*Laryngeal Squamous Papillary CA = HPV-16& 18 |
