When to Worry About a Rash in Adults?

Leukemia as a cause of skin rash

The most feared cause of skin rash in adults is leukemia, a type of blood cancer. However, it is by far one of the most uncommon causes. The majority of adults with a skin rash will be diagnosed either with infectious diseases or allergic reactions. But in some cases, it might be due to hemorrhagic causes, and leukemia should be ruled out sometimes.

Leukemia causes a skin rash because it is a dysfunction of the cells in the bone marrow. These cells produce red blood cells, white blood cells, and thrombocytes. By increasing the production of white blood cells exaggeratedly, leukemia impairs the production of other cell lines. Thus, the majority of patients have low levels of thrombocytes, and their blood clotting function becomes impaired.

However, as stated above, leukemia is not the most frequent cause of skin rash. This type of skin cancer is usually diagnosed through a combination of signs and symptoms, and not by having skin rash alone. Thus, let us review what signs and symptoms usually accompany skin rash in cases of leukemia and other life-threatening conditions in adults.
