E.N.T 5th year, 5th lecture (Dr. Sherko)

  1. 1. Tumours of the Pharynx<br />
  2. 2. TUMOURS OF THE NASOPHARYNX<br />Tumours of the nasopharynx can be benign or malignant. Benign tumours of the nasopharynx are rare. These are grouped as follows.<br />1. Juvenile angiofibroma<br />2. Hamatomas and dermoids<br />3. Craniopharyngiomas (from Rathke's pouch)<br />4. Lipoma, fibroma and neurofibroma<br />
  3. 3. TUMOURS OF THE NASOPHARYNX<br />Nasopharyngeal Angiofibroma<br />This is a benign but locally invasive lesion of the nasopharynx. It occurs almost exclusively in males between 10 to 25 years of age. The tumour tends to regress or stop growing after 25 years of age.<br />
  4. 4. TUMOURS OF THE NASOPHARYNX<br />Nasopharyngeal Angiofibroma<br />Pathology<br /> 1-Vascular component<br /> 2-Fibrous stroma<br />
  5. 5. TUMOURS OF THE NASOPHARYNX<br />Nasopharyngeal Angiofibroma<br />Spread of Tumour<br />The tumour from its origin in the nasopharynx, fills the nasopharyngeal space and may spread anteriorly to the nasal cavities. It may extend to pterygopalatinefossa and present in the orbit or cheek. The tumour can spread into the intracranial cavity by eroding its base or through it foramina.<br />
  6. 6. TUMOURS OF THE NASOPHARYNX<br />Clinical feature: nasal obstr and epistaxis<br />Investigation : biopsy ?<br />Ext carotid angiography<br />X ray <br />Treatment<br />Correction of anaemai and surgery<br />
  7. 7. TUMOURS OF THE NASOPHARYNX<br />Malignant Tumours of Nasopharynx<br />. Squamous cell carcinoma 60-75%. (commonest)<br />Aetiological Factors in Carcinoma of the Nasopharynx<br />This cancer is common in people of Chinese origin. Males are more commonly affected and growths are more common in the relatively younger age group. Epstien-Barr virus may be the cause, but its role is not clear. Susceptible genetic constitution plays a part.<br />
  8. 8. TUMOURS OF THE NASOPHARYNX<br />Malignant Tumours of Nasopharynx<br />
  9. 9. TUMOURS OF THE NASOPHARYNX<br />Malignant Tumours of Nasopharynx<br />Clinical feature<br />Nasal<br />Aural<br />Neurological<br />nodal<br />
  10. 10. TUMOURS OF THE NASOPHARYNX<br />Malignant Tumours of Nasopharynx<br />Diagnosis<br />Biopsy<br />Traement<br />radiotherapy<br />
  11. 11. TUMOURS OF THE OROPHARYNX<br />The common benign tumours from the oropharyngeal region include papilloma and plemorphic adenoma.<br />Papillomas<br />Papillomas usually arise on the soft palate or the faucial pillars and form mobile warty growths. They are mostly asymptomatic. Treatment is surgical excision. <br />Pleomorphic Salivary Adenoma<br />Tumour may sometimes arise from the salivary glandular tissue distributed over the palate or faucial region.<br />
  12. 12. TUMOURS OF THE OROPHARYNX<br /> <br />The commonest malignant neoplasm of this region is the squamous cell carcinoma.<br />SquamousCell Carcinoma in the Oropharyngeal Region<br />It may arise from tonsils, palate or the posterior pharyngeal wall. The disease is common in men than in women. There is strong relationship of this disease with smoking and betelnut chewing.<br />
  13. 13. TUMOURS OF THE OROPHARYNX<br />Squamous Cell Carcinoma in the Oropharyngeal region<br />Staging<br />T1—Tumour less than 2 cm in diameter.<br />T2—Tumour 2-4 cm in diameter.<br />T3—Tumour more than 4 cm.<br />T4—Massive tumours.<br />
  14. 14. TUMOURS OF THE OROPHARYNX<br />Squamous Cell Carcinoma in the Oropharyngeal region<br />Treatment<br />radiotherapy<br />
  15. 15. TUMORS OF THE LARYNGOPHARYNX<br />Squamous cell carcinoma (moderately differentiated) is the commonest type of cancer of this region.<br />Regions <br />Pyriformfossae<br />Post cricoid<br />Post pharyngeal wall<br />
  16. 16. TUMORS OF THE LARYNGOPHARYNX<br />Clinical features<br />Dysphagia<br />Muffled voice <br />Referred otalgia<br />Treatment<br />Surgery and radiotherapy<br />
