What is mycosis fungoides?
Mycosis fungoides is a form of T-cell lymphoma cancer, which largely manifests its symptoms on the skin. The skin itself is not cancerous, but cancerous T cells can be found on lesions, which occur in patches and may be scaly, pink and itchy. These patches can change, disappear, come back or stay the same. As the disease advances, lesions may turn into plaques.
Mycosis fungoides typically occurs in patients over 50 years old, in about one in 100,000 to 350,000 people. It is found all over the world, and in the United States, it affects approximately 3.6 per million citizens per year. It affects twice as many men as it does women.
