Patient Information Leaflets (PILs)

These Patient Information Leaflets (PILs) are specially written by the British Association of Dermatologists (BAD).

Please note:

  1. There are thousands of different skin complaints, therefore, the focus of the British Association of Dermatologists' PILs production is on the most common, rarest or debilitating skin conditions.
  2. The offer to provide details of source materials used to inform the British Association of Dermatologists' PILs is for instances where the advice provided in the PILs does not reflect local practice and therefore evidence supporting said advice needs to be produced. It is not an offer to conduct literature searches or supply bibilographic materials for your own research.

For the latest BAD advice on Covid-19 for patients, please check the News and Media section of the website. Find this here. Our information for healthcare professionals is here.

Kaposi's sarcoma

Kaposi’s sarcoma is a growth of the cells lining lymphatic vessels, caused by a virus in people with a weakened immune system. The virus is called human Herpes virus type 8 (Kaposi sarcoma herpes virus, HHV8). A common cause of the weakened immune system is HIV infection. It is named after Dr Moritz Kaposi, a Hungarian dermatologist, who first described it in 1872. ‘Sarcoma’ (from ancient Greek ‘flesh’) means a cancerous growth starting from abnormal cells of connective tissue.

Kaposi’s sarcoma can be limited, only affecting the skin, or more extensive with involvement of lymph nodes and internal organs such as the lungs or digestive system. It may be chronic which means it slowly gets worse, or it may rapidly worsen.
