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