Acroangiodermatitis (AAD), or Pseudo-Kaposi sarcoma (PKS), is a rare, benign skin condition, which can be seen by community nurses or in lymphoedema clinics, as it occurs in patients with lower limb oedema, chronic venous insufficiency (CVI), varicose vein removal, paralysis, congenital arteriovenous malformations (such as Klippel-Trenaunay and Parkes-Weber syndromes), or iatrogenic malformations caused by renal dialysis shunts or prosthetic suction limbs. AAD should be diagnosed by biopsy and differentiated from Kaposi sarcoma (KS), a rare malignancy with a similar presentation,
which is possible through histological differences. However, as said, the two conditions do present similarly, especially in the case of homosexual/bisexual men or human immunodeficiency virus (HIV) positive patients, as even with restored immune systems and an undetectable viral load, they are 30 times more likely to contract KS, which is malignant, than the general population. This article presents a clinical case, which is contrasted with past international case studies to portray a collective overview of AAD/PKS, and how to manage it effectively from the sparse literature available.
