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