The risk factors for cutaneous lymphoma are much the same as the risk factors for non-Hodgkin's lymphoma, including age, gender, and immune deficiency and infections.
Most cases of cutaneous lymphoma have no known cause, so it is difficult to prevent; however, keeping your immune system healthy by avoiding risk factors for HIV/AIDS may lower your risk.
Because this is a skin disease, it is often noticed fairly quickly. Unfortunately, cutaneous lymphomas can frequently resemble other, more common diseases of the skin, such as eczema or psoriasis, often leading to delays in diagnosis especially with early disease.
The symptoms of cutaneous lymphoma depend on the type you have, but may include:
- Patchy, scaly red or purple patches, lumps or bumps on or under the skin
- Widespread, itchy rash
- Thickened skin
- Red pimples, nodules or plaques on your scalp, forehead, or body
You should see a doctor if you notice a new skin lesion, especially if it is raised, doesn’t go away, or changes in shape or size.
Cutaneous lymphoma can only be diagnosed with tests, including blood tests, imaging tests, and biopsies. A biopsy is a procedure in which a sample of tissue is taken and viewed under a microscope or evaluated using laboratory tests.
