Hi Wendy. I would let oncologist know but would also get an appointment with a dermatologist. May or may not be related to CLL. Many things can give us rashes, etc(psoriasis, allergic reaction, etc) .

The skin is a very active zone for those bad WBC. I am very active and summer can cause a person’s body to be hot. I get “ Petechiae” with can look like a rash but it is circular dots at edge of rash. This is caused by exploding capillaries. When I jog or walk 5 or 6 miles and climb 20 to 30 flights of stairs this happens to my legs. It took me a month to clear my skin and avoid exercising stress.

That sounds really concerning, and it's completely understandable to want answers. A spreading rash like that definitely warrants a call to his doctor soon — don't wait for the next scheduled appointment.

CLL can affect the skin in several ways, and rashes are actually quite common. Since CLL and its treatments can weaken the immune system, the skin becomes more vulnerable. Some possibilities worth discussing with his doctor include:

- Skin infections — bacterial, viral, or fungal infections are more common with CLL due to a weakened immune system
- Insect bite-like reactions — some people with CLL develop itchy bumps that look like bug bites or rashes, even without any insect involvement
- Medication reactions — hives, itching, and rashes can be side effects of CLL treatments
- Leukemia cutis — in some cases, CLL cells can move into the skin, appearing as bumps, raised areas, or plaques One MyLeukemiaTeam member shared that they experienced terrible itching and hives as side effects from their CLL medication.

The fact that it's spreading from feet up to the torso is a reason to reach out to his hematologist or dermatologist promptly. They can properly identify the cause and recommend the right treatment.
