Lymphoma Cutaneous T Cell Anatomy

To better understand cutaneous T cell lymphoma, it helps to understand the anatomy of the lymphatic system.

The lymphatic system consists of a network of lymph vessels and lymph nodes throughout the body. The system transports a type of white blood cell, called lymphocytes. These cells play a role in fighting infection.

There are two main types of lymphocytes:

  • B lymphocytes
  • T lymphocytes

The lymphatic system performs two major functions:
  • Stores and transports cells that fight infection
  • Removes excess fluid from body tissues

The lymphatic system consists of:
  • Lymph vessels:
    • A network of vessels throughout the body that transport white blood cells called lymphocytes.
    • There are two main types of lymphocytes: B-cells and T-cells.
  • Lymph glands:
    • The lymph vessels connect in many areas known as lymph nodes.
    • The nodes act as filters to fight infection in the body.
    • Lymph nodes can enlarge in response to inflammation.
    • This can occur due to cancer or an infection nearby the lymph vessels.

Anatomy examples:
  • Areas of lymph nodes in the body
  • Areas in the body where lymph nodes can be felt
  • Abnormal lymph node cells due to Hodgkin's disease
  • Lymphatic system around the armpit and breast
  • Lymphatic system in the abdomen
