Adenomas

  1. 1. Gregory Noah Henry Lyfiona Wesley Ros Alwani Izatty Lim
  2. 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. 3.   Mixed tumor  Most common  Arise commonly from parotid gland (tail) Pleomorphic Adenoma
  4. 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. 5.   Biphasic:  Polygonal epithelial  Spindle-shaped myoepithelial  Stroma:  Mucoid  Fibroid  Vascular  Myxochondroid  Chondroid  Encapsulated with pseudopods Pleomorphic Adenoma
  6. 6.   FNAC  Imaging:  Ultrasound  CT scan  MRI Pleomorphic Adenoma
  7. 7.   Surgical:  Enucleation  high recurrence  Total / superficial parotidectomy Pleomorphic Adenoma
  8. 8.   Papillary cystadenoma lymphomatosum  Warthin tumor Adenolymphoma
  9. 9.   Male (5:1)  Usually arise from tail of parotid  Characteristic of tumor:  Rounded  Encapsulated  Cystic  Mucoid / brownish fluid Adenolymphoma
  10. 10.   Epithelial & lymphoid element  Stroma:  Lymphoid  Germinal center formation Adenolymphoma
  11. 11.   FNAC  Imaging:  Ultrasound  CT scan  MRI  Enucleation  Superficial parodiectomy Adenolymphoma
  12. 12.   Most common benign tumour of parotid in children Hemangioma
  13. 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. 14.   Surgical excision: If do not regress spontaneously Hemangioma
  15. 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. 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. 17.   Large dilated spaces  Formed by endothelial-lined space Lymphangiomas (Cystic Hygroma)
  18. 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)
  19. 19.  Thank You
