Kaposi’s Sarcoma – Definition

Kaposi’s sarcoma (KS) is a form of cancer. It affects the blood vessels. It can cause lesions on the skin, mucus membranes, or internal organs. It occurs most commonly in the gastrointestinal tract and lungs.

Cancer occurs when cells in the body divide without control or order. If cells keep dividing uncontrollably, a mass of tissue forms. This is called a growth or tumor. The term cancer refers to malignant tumors. They can invade nearby tissue and spread to other parts of the body.

KS can be classified according to the group of people that it affects:

  • Classic — usually affects men of Mediterranean descent
  • Endemic — usually affects people living in equatorial Africa
  • Transplant-related (acquired) — affects people who have received an organ transplant
  • AIDS-related (epidemic) — affects people with AIDS

Ichthyosis is a dry skin condition. There are two general types:

  • Inherited ichthyosis (several forms exist) — dryness and scaling of the skin due to hereditary factors
  • Acquired ichthyosis — thickening and scaling of the skin that is not inherited but is associated with certain medical disorders

Ichthyosis – Causes

Inherited ichthyosis is caused by a genetic defect that is passed from parent to child or that occurs spontaneously.

Acquired ichthyosis is relatively rare, but may be caused by any of the following:

  • Leprosy (extremely rare in the US)
  • Underactive thyroid
  • Lymphoma ( Hodgkin’s, Non-Hodgkin’s)
