Cutaneous T-cell lymphoma- Signs, Symptoms, Causes, Diagnosis and Treatment

Image

Cutaneous T-cell lymphoma (CTCL) is a rare type of cancer that begins in white blood cells called T cells (T lymphocytes). These cells normally help your body's germ-fighting immune system. In cutaneous T-cell lymphoma, the T cells develop abnormalities that make them attack the skin.

Cutaneous T-cell lymphoma can cause rash-like skin redness, slightly raised or scaly round patches on the skin, and, sometimes, skin tumors.

Several types of cutaneous T-cell lymphoma exist. The most common type is mycosis fungoides. Sezary syndrome is a less common type that causes skin redness over the entire body. Some types of cutaneous T-cell lymphoma, such as mycosis fungoides, progress slowly and others are more aggressive.

The type of cutaneous T-cell lymphoma you have helps determine which treatments are best for you. Treatments can include skin creams, light therapy, radiation therapy and systemic medications, such as chemotherapy.

Cutaneous T-cell lymphoma is one of several types of lymphoma collectively called non-Hodgkin's lymphoma.

Symptoms

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
  • Enlarged lymph nodes
  • Hair loss
  • Thickening of the skin on the palms of the hands and soles of the feet
  • A rash-like skin redness over the entire body that is intensely itchy

Causes

The exact cause of cutaneous T-cell lymphoma isn't known.

In general, cancer begins when cells develop changes (mutations) in their DNA. A cell's DNA contains instructions that tell a cell what to do. The DNA mutations tell the cells to grow and multiply rapidly, creating many abnormal cells.

In cutaneous T-cell lymphoma, the mutations cause too many abnormal T cells that attack the skin. T cells are part of your immune system, and they normally help your body fight germs. Doctors don't know why the cells attack the skin.

Diagnosis

  • Physical exam
  • Blood tests
  • Skin biopsies
  • Imaging tests

Treatment

  • Treatment options may include:
  • Skin creams and ointments
  • Light therapy (phototherapy)
  • Radiation therapy
  • Medications
  • Exposing blood cells to light
  • Bone marrow transplant
