Staging
Following are stages for mycosis fungoides and Sézary syndrome:
• Stage IA: Less than 10% of the skin is covered in red patches or
plaques.
• Stage IB: 10% or more of the skin is covered in patches or
plaques.
• Stage IIA: Any amount of the skin surface is covered with
patches or plaques and lymph nodes are enlarged and inflamed,
but the cancer has not spread to the nodes.
• Stage IIB: One or more tumors are found on the skin, lymph
nodes may be enlarged, but cancer has not spread to the nodes.
• Stage III: Nearly all of the skin is reddened and may have
patches, plaques or tumors; lymph nodes may be enlarged, but
cancer has not spread to them.
• Stage IVA: Most of the skin is reddened and malignant cells
are found in the blood; cancer has spread to the lymph nodes.
• Stage IVB: Most of the skin is red, any amount of skin is
covered in patches, plaques or tumors, cancer has spread to
other organs.
