Kaposi Sarcoma

The cancer Kaposi Sarcoma (KS) affects the cells lining blood arteries, causing them to develop abnormally and create tumors or lesions. While KS can develop everywhere on the body, it is most frequent on the foot, where it manifests as slow-growing red or purple lesions.

Connection between KS and Foot

The clinical types of KS on the foot are classed as:

  1. Classic,
  2. Endemic
  3. Iatrogenic
  4. Epidemic (HIV-associated).

The classic form, which manifests as slow-growing lesions on the skin of the lower limbs, particularly the feet, is more frequent in older men of Mediterranean or Eastern European ancestry.

The endemic strain is widespread in Africa and causes a more severe sickness with lymph node and other internal organ involvement.

The iatrogenic form is linked to immunosuppressive therapy or organ transplantation, whereas the epidemic form is linked to HIV infection.

Depending on the kind and stage of the illness, the appearance of KS lesions on the foot might vary. KS on the foot may manifest as tiny, flat or elevated red or purple patches that mimic bruises in the early stages. These patches may gradually thicken and become more noticeable over time. Lesions can be unpleasant in some situations, especially if they form on the sole of the foot or other weight-bearing regions.


KS on the foot is commonly diagnosed using a combination of visual examination, biopsy, and imaging studies such as X-rays or CT scans. A tiny sample of tissue may be taken and analyzed under a microscope if a lesion is thought to be KS. Imaging tests may also be performed to assess the severity of the disease and if it has spread to other sections of the body.


The kind and stage of the illness, as well as the individual's overall health and other medical issues, all influence treatment for KS on the foot. If the lesions are tiny and not producing any symptoms, no treatment may be required. But, if the lesions are developing or causing discomfort, surgery, radiation therapy, or chemotherapy may be recommended. In certain circumstances, medications that target the blood arteries that feed the tumors, such as bevacizumab, may be employed.
