How do you identify Sézary cells?
Blood tests: A complete blood count and peripheral blood smear check your red and white blood cells, platelets and hemoglobin. Blood flow cytometry can detect cancerous cells in your blood . Immunophenotyping: A blood or tissue sample can reveal markers present on cell surfaces.
What are Sézary cells?
(sey-zah-REE sel) A cancerous T cell (a type of white blood cell) found in the blood, skin, and lymph nodes of patients who have a fast-growing type of skin lymphoma called Sézary syndrome. Under a microscope, Sézary cells have an abnormally shaped nucleus and look larger than normal T cells.
How do you differentiate mycosis fungoides and Sezary syndrome?
Mycosis fungoides and Sézary syndrome are types of cutaneous T-cell lymphoma. A sign of mycosis fungoides is a red rash on the skin. In Sézary syndrome, cancerous T-cells are found in the blood. Tests that examine the skin and blood are used to diagnose mycosis fungoides and Sézary syndrome.
What does cutaneous T-cell lymphoma look like?
Signs and symptoms of cutaneous T-cell lymphoma include: Round patches of skin that may be raised or scaly and might be itchy. Patches of skin that appear lighter in color than surrounding skin. Lumps that form on the skin and may break open.
What does lymphoma of the skin look like?

What are hairy cells?
Hairy cell leukemia is a cancer of the blood and bone marrow. This rare type of leukemia gets worse slowly or does not get worse at all. The disease is called hairy cell leukemia because the leukemia cells look “hairy” when viewed under a microscope.
How do you rule out mycosis fungoides?
Mycosis fungoides is a type of skin lymphoma (cancer). It occurs when white blood cells become cancerous….To confirm or rule out mycosis fungoides, your healthcare provider will likely use additional tests such as:
- Skin biopsy or lymph node biopsy.
- Blood tests.
- CT scans.
- PET scans.
What causes Sezary syndrome?
Causes. The cause of Sézary syndrome is unknown. Most affected individuals have one or more chromosomal abnormalities, such as the loss or gain of genetic material. These abnormalities occur during a person’s lifetime and are found only in the DNA of cancerous cells.
What is the difference between B cell and T-cell lymphoma?
While B cells produce the antibodies that target diseased cells, T cells directly destroy bacteria or cells infected with viruses. This type of lymphoma is a fast-growing disease that is treated more like acute leukemia.
What does T-cell lymphoma look like?
Are lymphoma lumps visible?
One common symptom of lymphoma is swollen lymph nodes, which can create visible lumps under the skin, usually in the neck, armpit or groin area.
