Red spots on the skin that do not itch may be a sign of skin cancer, psoriasis, idiopathic thrombocytopenic purpura, or other causes.
Red spots caused by skin cancer usually appear in the areas most exposed to the sun. The lesions usually bleed, do not heal, grow over time and usually do not itch. However, there is a very aggressive form of skin cancer, the melanoma, which spots can be painful and itchy.
THE psoriasis is a disease of genetic origin, non-contagious, that causes inflammation of the skin. It manifests mainly in the knees, elbows and scalp, in the form of red patches on the skin that do not cause itching and peeling.
Already the idiopathic thrombocytopenic purpura is an autoimmune disease that affects the platelets, cells responsible for blood clotting. As a result of the destruction of these cells by the person's own immune system, red or purple spots appear on the body, in addition to bleeding in the digestive and urinary tract, gums and nose.
Seek a dermatologist in the presence of these symptoms or if the red spots do not disappear from the skin within a few days.
