Please add some details. 123456789101112131415 Salivary Gland Disease | Level I 1 / 15 Patient presents with rapidly growing parotid mass and facial weakness. Most concerning for? Pleomorphic adenoma Adenoid cystic carcinoma Mucoepidermoid carcinoma Warthin tumor Facial nerve involvement, rapid growth, pain, and fixation strongly suggest malignancy. Requires immediate biopsy. 2 / 15 During parotidectomy, which structure most reliably identifies the facial nerve trunk? Retromandibular vein Tragal pointer Styloid process 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. 3 / 15 Patient develops xerostomia after starting new medication. Most likely class? Antihypertensives Antibiotics Anticholinergics Antidepressants Anticholinergics are most common cause of drug-induced xerostomia through muscarinic blockade. 4 / 15 A woman with dry eyes, dry mouth, joint pain. Most likely diagnosis? Lymphoma Sjögren's syndrome Arthritis IgG4 disease Sjögren's syndrome - autoimmune condition affecting salivary and lacrimal glands. Associated with positive SSA/Ro antibodies. 5 / 15 The most common complication of submandibular stone removal is Bleeding Infection Duct stricture Lingual nerve injury Lingual nerve injury is most common due to close anatomical relationship in floor of mouth. 6 / 15 Which of the following conditions may require immediate surgical treatment? Ranula Deep lobe abscess Viral sialadenitis Sialolithiasis Deep lobe parotid abscess can spread to parapharyngeal space causing airway compromise. Treatment includes broad spectrum antibiotics and drainage. 7 / 15 Patient post-radiation with severe dry mouth. Best initial treatment? Antibiotics Pilocarpine Artificial saliva Surgery Pilocarpine stimulates residual salivary function. Start with salivary substitutes and maintain oral hygiene. 8 / 15 The most concerning feature of malignant transformation in pleomorphic adenoma is Pain Rapid growth Facial weakness Firmness Rapid growth in longstanding pleomorphic adenoma suggests malignant transformation (carcinoma ex pleomorphic adenoma). 9 / 15 Child presents with bilateral painful parotid swelling. Most likely cause? Juvenile recurrent parotitis Viral sialadenitis Stones Bacterial infection Viral sialadenitis (commonly mumps) is most common cause of bilateral parotid swelling in children. 10 / 15 A patient with HIV presents with bilateral parotid enlargement. The most likely underlying pathology is Viral sialadenitis Lymphoma Lymphoepithelial cysts Bacterial infection HIV-associated lymphoepithelial cysts are common in HIV. Presents as bilateral, painless parotid enlargement. 11 / 15 A 45-year-old presents with a painless, slowly growing mass in the parotid. What is the most common benign tumor? Warthin tumor Pleomorphic adenoma Oncocytoma Basal cell adenoma Pleomorphic adenoma is the most common benign tumor (80% of benign parotid tumors). Typically presents as painless, slow-growing mobile mass. 12 / 15 The most appropriate initial imaging for suspected salivary stone is CT scan Ultrasound Sialogram MRI Ultrasound is first-line - no radiation, can visualize stones, assess duct dilation, and guide procedures. 13 / 15 The most reliable test for Sjögren's syndrome diagnosis is Salivary flow Minor gland biopsy Schirmer test Anti-SSA antibodies Minor salivary gland biopsy showing focal lymphocytic sialadenitis has highest specificity for diagnosis. 14 / 15 A 50-year-old man has painful submandibular swelling during meals. Most likely diagnosis? Sialolithiasis Sialadenitis Ranula Tumor Sialolithiasis most commonly affects submandibular gland (80-90%) due to tortuous duct and calcium-rich secretions. 15 / 15 The most common malignant tumor of minor salivary glands is Mucoepidermoid Acinic cell Adenoid cystic Squamous cell Adenoid cystic carcinoma is most common in minor glands, especially palate. Known for perineural invasion. Your score is LinkedIn Facebook Twitter 0% Restart quiz
