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 6

Created by Prof. Mike Dixon

Female age 32

Tissue: Lymph node

The patient presented with enlarged lymph nodes in the neck. She had been aware of a gradual increase in size over the past 4 months. Otherwise she felt well, but she had noticed in recent weeks that she felt dizzy and flushed after drinking alcohol. On imaging she was found to have enlargement of the mediastinal nodes. A lymph node was removed from the lower neck for histological diagnosis.

This spleen comes from a similar case to the lymph node below. It has been surgically removed and photographed before fixation. The organ is enlarged and the capsule is distorted by numerous pale nodules elevating the surface. On sectioning they were scattered throughout the splenic pulp.
