1. Red or Purple Patches on the Skin
Red or purple raised patches can be a sign of Kaposi sarcoma. This skin cancer is very rare and generally occurs in people with AIDS or organ recipients.
It is sometimes found in young men living in Africa or older men of Italian or Eastern European Jewish ancestry.
Kaposi sarcoma develops in the skin’s blood vessels and creates painless lesions or tumors, most commonly on the face or legs. Tumors on the legs or groin may make the legs swell painfully.
