What does erythroplakia look like?
Red, velvety patch…may be flat or slightly rounded
Who gets erythroplakia?
Adult tobacco users
What is the concern with erythroplakia?
Precancerous dysplasia…more so than with leukoplakia (erythroplakia is red because of blood supply)
What does actinic cheilosis look like?
Actinic cheilosis is a leukoplakic lesion of the lower lip that causes a loss of distinct demarcation between lip and skin

What are the common risk factors for oral cavity, oropharyngeal, hypopharyngeal, and laryngeal SCC?
Tobacco use
EtOH use
HPV
What is the biggest risk factor for nasopharyngeal SCC?
EBV
A patient has oral cavity or pharyngeal SCC, where are the most likely locations for metastases?
Cervical neck lymph nodes (typical presenting sign)
Mediastinal lymph nodes, lungs, liver, bone
What is xerostomia?
Dry mouth due to decreased saliva production
What are some possible causes of xerostomia?
Sjogren’s syndrome
Previous radiation therapy
Some medications
What is sialadenitis? What can be seen?
Inflammation of the salivary gland
There is a bulge/nodule/bump/etc
What are some possible causes of sialadenitis?
Trauma
Bacterial or viral infection (mumps)
Autoimmune disease (Sjogren’s)
What is the name of an autoimmune disease against salivary glands that produces a bulge/nodule/bump/etc?
Lymphoepithelial sialadenitis (LESA)
What is a possible cause of LESA?
Sjogren’s
What is a mucocele?
A mucocele is a fluid filled mucosal nodule caused by a minor salivary gland leaking
What are three types of mucocele?
Retention mucocele (caused by obstruction) Extravastion mucocele (caused by trauma) Ranula (mucocele of the sublingual gland)
What is the most common salivary gland tumor? What gland does it usually occur in?
Pleomorphic adenoma is the most common salivary gland tumor
Pleomorphic adenoma is most likely to occur in the parotid gland
What is the microscopic appearance of pleomorphic adenoma?
Mix of proliferating appearance
Mesenchymal matrix of myxoid, hyaline, and chondroid tissue
What are some gross features of pleomorphic adenoma?
Usually a discreet, painless mass that seems well circumscribed (but isn’t…still rarely becomes a carcinoma)
What is the second most common salivary gland tumor? What gland does it usually form in?
Warthin tumor
The parotid gland
What is the microscopic appearance of Warthin tumor?
Papillary, cystic lesion (dual layer of bland, neoplastic, eosinophilic epithelium
Associated with reactive lymphoid stroma
Well encapsulated
What is warthin tumor associated with?
Warthin tumor is associated with reactive lymphoid stroma
Smokers
What is the most common MALIGNANT salivary gland tumor (in adults AND kids)?
Mucoepidermoid carcinoma
What are some microscopic features of mucoepidermoid carcinoma?
Mixture of squamous cells, mucus-secreting cells, and intermediate cells
Appear encapsulated, but aren’t…infiltrate at margins
What is the most common malignant tumor of the MINOR salivary glands?
Adenoid cystic carcinoma
What are some features of adenoid cystic carcinoma?
It is slow growing
Its 5-year survival rate starts at 70% and then gets cut in half every five years
What are esophageal mucosal webs?
Protrusions of mucosa –> possible obstruction
Usually in upper esophagus
What are some differences between esophageal mucosal webs and Schatzki rings (esophageal rings)?
Schatzki rings are thicker and circumferential, may contain muscularis propria, occur in the lower esophagus
What is Zenker’s diverticulum?
An outpouching of mucosa and submucosa through a weakened posterior cricopharyngeus muscle (above the UES)
Is Zenker’s diverticulum a true diverticulum?
No…can become large enough to accumulate food and cause problems
