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