Three source-backed schematics turn the page into a map, a mechanism, and a discriminator.
Commit before the lesson
A patient has recurrent swelling and colicky pain beneath the mandible that begins just before meals and improves afterward. Palpation of the floor of mouth reproduces the pain.
Which diagnosis is most likely?
Reason it through
What makes symptoms appear?Salivary stimulation during anticipation and eating.
Which duct has an uphill course and viscous secretion?Wharton duct from the submandibular gland.
Pain with meals is a plumbing problem until proven otherwise.
Ulcer, stone, infection, or cancer
Time course and trigger narrow the oral differential before biopsy or imaging.
Aphthous ulcers are painful, shallow, round or oval mucosal defects with a fibrinous yellow-gray base and erythematous rim that usually heal without scarring.
Sialolithiasis causes obstructive gland pain and swelling with salivary stimulation; secondary sialadenitis adds persistent tenderness, erythema, fever, or purulent duct drainage.
Oral squamous-cell carcinoma commonly presents as a persistent ulcer, indurated mass, leukoplakic or erythroplakic lesion, or unexplained pain and is associated with tobacco, alcohol, and selected HPV-related sites.
Switch among the lesion patterns.
Painful shallow recurrent ulcer on nonkeratinized mucosa; usually self-limited.
Preprandial or meal-related gland pain and swelling from duct obstruction.
Inflamed tender gland from obstruction, bacterial or viral infection, or autoimmune disease.
Nonhealing indurated ulcer or mass, irregular raised border, red or white precursor lesion, or cervical nodes.
Recurrent and healing suggests aphthae; persistent and indurated demands tissue diagnosis.
How a stone becomes an infection
Stasis removes the gland's mechanical defense and invites ascending oral bacteria.
Dehydration, thick saliva, duct anatomy, or local injury promotes mineral precipitation and obstruction.
Salivary stimulation raises pressure behind the obstruction, creating the classic meal-related pain and swelling.
Prolonged stasis permits ascending bacterial infection, often with acute tenderness and purulence; recurrent injury can produce chronic sialadenitis and gland fibrosis.
Reveal the obstruction-to-infection sequence.
Salivary flow slows or precipitate formsA calculus develops within a major salivary duct.
Meal stimulation increases secretionPressure rises behind the obstructed duct.
Gland becomes painful and swollenSymptoms peak around eating.
Oral bacteria ascend through stagnant ductAcute bacterial sialadenitis develops.
Repeated inflammation scars the glandChronic dysfunction and recurrent episodes follow.
The smaller the gland, the larger the malignancy concern
Most salivary tumors occur in parotid, but location changes the probability of malignant behavior.
Most parotid tumors are benign, and pleomorphic adenoma is the most common benign salivary neoplasm.
A progressively larger share of tumors are malignant in submandibular, minor, and especially sublingual glands, so an uncommon location deserves greater suspicion.
Pain, rapid growth, fixation, skin or mucosal ulceration, cervical nodes, and facial-nerve weakness are red flags for malignant invasion.
Which feature most strongly suggests salivary malignancy?
A painless mass can still be cancer, but nerve weakness is an alarm bell.
Know the gland and its duct
Anatomic route explains which stones can be palpated and which infections threaten the facial nerve region.
Parotid glands drain through Stensen ducts across the masseter and through buccinator opposite the upper second molar; the facial nerve traverses the gland but does not provide its secretomotor supply.
Submandibular glands wrap around the mylohyoid and drain through long Wharton ducts to the sublingual caruncles beside the frenulum, making distal stones accessible in the floor of mouth.
Sublingual glands drain through multiple small ducts along the sublingual fold and are less often the site of stones but carry a higher malignancy proportion when a neoplasm occurs.
Open each gland and route.
Three salivary tumors worth separating
Histology and patient pattern distinguish the common benign tumors from the common malignant one.
Pleomorphic adenoma is a benign mixed epithelial and myoepithelial tumor with chondromyxoid stroma; incomplete excision or capsular rupture increases recurrence risk, and long-standing lesions can transform malignantly.
Warthin tumor is a benign cystic oncocytic parotid tumor with lymphoid stroma, strongly associated with smoking and capable of being bilateral or multifocal.
Mucoepidermoid carcinoma is a common malignant salivary tumor composed of mucous, squamoid, and intermediate cells; grade and stage determine behavior.
Open each tumor profile.
Pleomorphic adenoma
Most common benign salivary tumor; mobile painless parotid mass; mixed epithelial and chondromyxoid appearance; recurrence if incompletely excised.
Warthin tumor
Benign cystic parotid tumor in smokers; oncocytic epithelium with lymphoid germinal centers; may be bilateral.
Mucoepidermoid carcinoma
Common malignant salivary histology with mucous and epidermoid cells; low- and high-grade forms.
Carcinoma ex pleomorphic adenoma
Rapid change, pain, fixation, or nerve deficit in a long-standing pleomorphic adenoma suggests malignant transformation.
Malignancy probability rises as gland size falls
Parotid produces most tumors; sublingual and minor glands produce fewer but more suspicious tumors.
A parotid mass is statistically more likely benign than a mass arising in a smaller major gland, although metastatic skin cancer and primary malignancy remain important.
Submandibular, sublingual, and minor-gland masses carry progressively greater malignant concern and should not be reassured by painless presentation alone.
Classify each site by relative probability that a salivary neoplasm is malignant.
Most tumors choose parotid; malignancy chooses the smaller glands more often.
