What is SÚzary syndrome?
SÚzary syndrome is an aggressive form of a type of cancer called cutaneous T-cell lymphoma. Cutaneous T-cell lymphomas occur when certain immune cells, called T cells, become cancerous; these cancers characteristically affect the skin, causing different types of skin lesions. In SÚzary syndrome, the cancerous T cells are called SÚzary cells and are found in the skin, lymph nodes, and blood. A characteristic of SÚzary cells is an abnormally shaped nucleus, described as cerebriform.
People with SÚzary syndrome develop a red, severely itchy rash (erythroderma) that covers large portions of their body. SÚzary cells are found in the rash. However, the skin cells themselves are not cancerous; the skin problems result when SÚzary cells move from the blood into the skin. People with SÚzary syndrome also have enlarged lymph nodes (lymphadenopathy). Other common signs and symptoms of this condition include hair loss (alopecia), thickened skin on the palms of the hands and soles of the feet (palmoplantar keratoderma), abnormalities of the fingernails and toenails, and lower eyelids that turn outward (ectropion). Some people with SÚzary syndrome are less able to control their body temperature than people without the condition.
The cancerous T cells can spread to other organs in the body, including the lymph nodes, liver, spleen, and bone marrow. In addition, affected individuals have an increased risk of developing another lymphoma or other type of cancer.
SÚzary syndrome occurs in adults over age 60 and progresses rapidly; historically, affected individuals survived an average of 2 to 4 years after development of the condition, although survival has improved with newer treatments.
Although SÚzary syndrome is sometimes referred to as a variant of another cutaneous T-cell lymphoma called mycosis fungoides, these two cancers are generally considered separate conditions.

How common is SÚzary syndrome?
SÚzary syndrome is a rare condition, although its prevalence is unknown. It is the second most common form of cutaneous T-cell lymphoma after mycosis fungoides, accounting for approximately 3 to 5 percent of cases of cutaneous T-cell lymphoma.
What genes are related to SÚzary syndrome?
The cause of SÚzary 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. Abnormalities have been found on most chromosomes, but some regions are more commonly affected than others. People with this condition tend to have losses of DNA from regions of chromosomes 10 and 17 or additions of DNA to regions of chromosomes 8 and 17. It is unclear whether these alterations play a role in SÚzary syndrome, although the tendency to acquire chromosomal abnormalities (chromosomal instability) is a feature of many cancers. It can lead to genetic changes that allow cells to grow and divide uncontrollably.
How do people inherit SÚzary syndrome?
The inheritance pattern of SÚzary syndrome has not been determined. This condition occurs in people with no history of the disorder in their family and is not thought to be inherited in most cases.
