Hypopharngeal Tumors

👉Histopathologic types of tumors of the hypopharynx:
1. The most common (90% to 95%) histologic type of cancer is squamous cell carcinoma.

2. Other malignant tumours present in a similar manner either with ulceration or as a non-ulcerative swelling:
– Malignant minor salivary gland tumors

– Lymphomas

– Sarcomas

👉Macroscopic pathology:
1. The majority of tumors present as ulcers and are widely infiltrative.
2. They have a tendency to extend submucosally and also also to metastasize to the local lymph nodes.

1. The hypopharynx is an uncommon site of tumors, the majority being malignant, and accounts for less than 10% of all squamous cell carcinomas overall.
2. The overall incidence in the Western world is one case per 100 000 per year:
– 1800 new cases each year of hypo pharyngeal cancers are reported in the USA.
3. There is a high incidence in Northern France of 14.8 per 100 000 per year, which accounts for 18% of head and neck cancer seen in France.
5. The mean age at presentation is 60 years.
6. The piriform sinus and posterior pharyngeal wall carcinomas demonstrate a male dominance: – 5 to 20 : 1.
7. Postcricoid lesions unlike other sites, shows a moderate female preponderance 1.5 : 1.
