Living with Mycosis fungoides

The most common form of cutaneous T-cell lymphoma, a blood cancer that shows up on the skin as patches, plaques, or tumors.

Understanding Mycosis fungoides

Mycosis fungoides is the most common type of cutaneous T-cell lymphoma, a blood cancer in which cancerous T cells affect the skin.

The skin cells themselves are not cancerous. The skin problems happen when cancerous T cells move from the blood into the skin. It usually appears in adults over age 50, although children can be affected. It may progress slowly through stages: patches (flat, scaly, red or pink areas that can itch), then plaques (raised lesions), then sometimes tumors. Not everyone goes through every stage.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Flat, scaly pink or red patches (often itchy)
  • Raised skin plaques
  • Itching
  • Skin tumors
  • Redness of the skin
  • Swollen lymph nodes

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include blood and bone marrow specialists, cancer specialists and skin, hair, and nail specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Cutaneous Lymphoma Foundation may keep lists of experts for this condition.
