The most likely underlying pathology is Bacterial infection Viral sialadenitis Lymphoepithelial cysts Lymphoma HIV-associated lymphoepithelial cysts are common in HIV. Presents as bilateral, painless parotid enlargement. 2 / 15 Patient develops xerostomia after starting new medication. Most likely class? Antidepressants Antihypertensives Antibiotics Anticholinergics Anticholinergics are most common cause of drug-induced xerostomia through muscarinic blockade. 3 / 15 The most common malignant tumor of minor salivary glands is Acinic cell Mucoepidermoid Squamous cell Adenoid cystic Adenoid cystic carcinoma is most common in minor glands, especially palate. Known for perineural invasion. 4 / 15 Patient presents with rapidly growing parotid mass and facial weakness. Most concerning for? Warthin tumor Pleomorphic adenoma Mucoepidermoid carcinoma Adenoid cystic carcinoma Facial nerve involvement, rapid growth, pain, and fixation strongly suggest malignancy. Requires immediate biopsy. 5 / 15 Patient post-radiation with severe dry mouth. Best initial treatment? Surgery Artificial saliva Antibiotics Pilocarpine Pilocarpine stimulates residual salivary function. Start with salivary substitutes and maintain oral hygiene. 6 / 15 A woman with dry eyes, dry mouth, joint pain. Most likely diagnosis? Sjögren's syndrome IgG4 disease Arthritis Lymphoma Sjögren's syndrome - autoimmune condition affecting salivary and lacrimal glands. Associated with positive SSA/Ro antibodies. 7 / 15 Which of the following conditions may require immediate surgical treatment? Ranula Deep lobe abscess Sialolithiasis Viral sialadenitis Deep lobe parotid abscess can spread to parapharyngeal space causing airway compromise. Treatment includes broad spectrum antibiotics and drainage. 8 / 15 The most reliable test for Sjögren's syndrome diagnosis is Anti-SSA antibodies Salivary flow Schirmer test Minor gland biopsy Minor salivary gland biopsy showing focal lymphocytic sialadenitis has highest specificity for diagnosis. 9 / 15 The most appropriate initial imaging for suspected salivary stone is Ultrasound CT scan MRI Sialogram Ultrasound is first-line - no radiation, can visualize stones, assess duct dilation, and guide procedures. 10 / 15 A 45-year-old presents with a painless, slowly growing mass in the parotid. What is the most common benign tumor? Warthin tumor Oncocytoma Basal cell adenoma Pleomorphic adenoma Pleomorphic adenoma is the most common benign tumor (80% of benign parotid tumors). Typically presents as painless, slow-growing mobile mass. 11 / 15 During parotidectomy, which structure most reliably identifies the facial nerve trunk? Styloid process Retromandibular vein Tragal pointer Digastric muscle The tragal pointer is a reliable landmark - facial nerve is 1-2cm deep and anterior to it, lying just inferior to the tympanomastoid suture. 12 / 15 A 50-year-old man has painful submandibular swelling during meals. Most likely diagnosis? Ranula Tumor Sialolithiasis Sialadenitis Sialolithiasis most commonly affects submandibular gland (80-90%) due to tortuous duct and calcium-rich secretions. 13 / 15 Child presents with bilateral painful parotid swelling. Most likely cause? Bacterial infection Stones Viral sialadenitis Juvenile recurrent parotitis Viral sialadenitis (commonly mumps) is most common cause of bilateral parotid swelling in children. 14 / 15 The most common complication of submandibular stone removal is Bleeding Lingual nerve injury Infection Duct stricture Lingual nerve injury is most common due to close anatomical relationship in floor of mouth. 15 / 15 The most concerning feature of malignant transformation in pleomorphic adenoma is Rapid growth Facial weakness Firmness Pain Rapid growth in longstanding pleomorphic adenoma suggests malignant transformation (carcinoma ex pleomorphic adenoma).
