Week 8

Lecture outline

The remaining three weeks are devoted to neoplasia which accounts for 25% of deaths in the population. The principles of benign and malignant tumours are described and their classification explained.

Tumour Classification 5

Created by Prof. Mike Dixon

Male age 28

Tissue: Parotid gland

The patient had noticed increasing swelling at the angle of his jaw on the left side over many months. There was no pain or tenderness. He only sought medical attention when his partner became alarmed and insisted that he saw a doctor. Following clinical examination he underwent a CT scan and subsequently had resection of the tumour followed by irradiation of the parotid region.

A slice across the parotid gland reveals a well circumscribed tumour composed of white 'glassy' - possibly cartilaginous, tissue together with some apparently mucinous areas. There is a narrow rim of salivary tissue around the tumour.
