Kaposi sarcoma is a rare skin cancer that is often associated with people with HIV/AIDS. This people group and others with weakened immune systems (such as organ transplant patients) are most likely to develop Kaposi sarcoma. Others with an increased risk include young men who live in Africa, older men who are Italian or have Eastern European Jewish heritage.
Kaposi sarcoma develops in the blood vessels of your skin; it presents as red or purple spots on either the skin or the mucous membranes.
Merkel cell carcinoma is most often associated with the elderly. The skin cancer lesion is usually flesh-colored or bluish- red, and it is usually found on the face, head, or neck. Sun exposure and decreased immune system are two warning factors for this cancer. It grows fairly fast and spreads to other parts of the body.
Sebaceous gland carcinoma is both a rare and aggressive form of skin cancer. It develops in the skin’s oil glands. These skin cancers, hard and painless, can occur anywhere but are most common on the eyelid. Because of their location, they are often misdiagnosed at first for other eye ailments.
If you have anything new or different on your skin – and please do a monthly self skin check – contact your dermatologist immediately. Not all skin changes mean skin cancer; your doctor can test, diagnose, and guide you through the best treatment plan for you.
