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