Adenomas
- 1. Gregory Noah Henry Lyfiona Wesley Ros Alwani Izatty Lim
- 2. ο ο Benign ο 80% parotid gland, followed by submandibular gland and other minor salivary gland Introduction Epithelial Mesenchymal Pleomorphic adenoma Hemangioma Adenolymphoma (Warthin tumor) Lymphangioma Oncocytoma Lipoma Other adenomas Neurofibroma
- 3. ο ο Mixed tumor ο Most common ο Arise commonly from parotid gland (tail) Pleomorphic Adenoma
- 4. ο ο 30-40 y/o ο Female ο Characteristic of tumor: ο Slow growing ο Painless ο Firm, single nodular mass ο Dysphagia (if deep lobe if involve) ο Deviation of uvula & pharyngeal wall towards midline ο Facial nerve not involve ο Malignant transformation Pleomorphic Adenoma
- 5. ο ο Biphasic: ο Polygonal epithelial ο Spindle-shaped myoepithelial ο Stroma: ο Mucoid ο Fibroid ο Vascular ο Myxochondroid ο Chondroid ο Encapsulated with pseudopods Pleomorphic Adenoma
- 6. ο ο FNAC ο Imaging: ο Ultrasound ο CT scan ο MRI Pleomorphic Adenoma
- 7. ο ο Surgical: ο Enucleation ο high recurrence ο Total / superficial parotidectomy Pleomorphic Adenoma
- 8. ο ο Papillary cystadenoma lymphomatosum ο Warthin tumor Adenolymphoma
- 9. ο ο Male (5:1) ο Usually arise from tail of parotid ο Characteristic of tumor: ο Rounded ο Encapsulated ο Cystic ο Mucoid / brownish fluid Adenolymphoma
- 10. ο ο Epithelial & lymphoid element ο Stroma: ο Lymphoid ο Germinal center formation Adenolymphoma
- 11. ο ο FNAC ο Imaging: ο Ultrasound ο CT scan ο MRI ο Enucleation ο Superficial parodiectomy Adenolymphoma
- 12. ο ο Most common benign tumour of parotid in children Hemangioma
- 13. ο ο Children, predominantly affecting females ο Mostly discovered at birth ο Characteristic of tumor: ο Grow rapidly in the neonatal period & then involute spontaneously ο Soft ο Painless ο Increase in size with crying or straining ο Overlying skin: May show bluish discoloration Hemangioma
- 14. ο ο Surgical excision: If do not regress spontaneously Hemangioma
- 15. ο ο Less common ο May involve parotid & submandibular gland ο Due to lymphatic sequestration of primitive embryonic lymph duct that undergo irregular growth and canalization. Lymphangiomas (Cystic Hygroma)
- 16. ο ο Can occur at any age, any part of body ο More common in children < 2 years, involve head & neck ο Characteristic of tumor: ο Slow growing ο Soft (doughy) ο Cystic ο Usually painless ο Spongy, multiloculated mass ο Yellowish or bluish surface ο Airway obstruction & swallowing difficutly Lymphangiomas (Cystic Hygroma)
- 17. ο ο Large dilated spaces ο Formed by endothelial-lined space Lymphangiomas (Cystic Hygroma)
- 18. ο ο HPE ο Prenatal Case: ο Ultrasound ο Amniocentesis ο Medical: ο sclerosing agents: ο OK-432 (an inactive strain of group A Streptococcus pyogenes) ο Bleomycin ο pure ethanol ο sodium tetradecyl sulfate ο doxycycline ο Surgical excision ο Preservation of vital structure ο Cosmetic reason Lymphangiomas (Cystic Hygroma)
