The most common skin changes for patients with MDS are rashes or injection site reactions. A rash is a change of the skin which affects its color, appearance, or texture. A rash may be localized in one part of the body, or affect all of the skin. Rash is generally caused by a skin irritation that can result from chemotherapy, allergy, infection, or skin problem. Certain skin changes may indicate more severe skin infections, such as shingles.
