Mycosis fungoides basics

Review

Review

• The lymphatic system consists of lymph and

a network of vessels and organs. It helps kill

germs in the body and transports fluids to the

bloodstream.

• Lymphomas are cancers that start in

lymphocytes within the lymphatic system.

Mycosis fungoides is a cancer of T-cells that

collect in the skin.

• The most common symptom of mycosis

fungoides is skin lesions.

• One or more skin biopsies are needed to

diagnose mycosis fungoides.

• The biopsy tissue should be tested by a

dermatopathologist, hematopathologist, or

both. The pathologist will study your skin cells

with a microscope and may test for surface

proteins, Sézary cells in blood, and abnormal

genes.
