The term pseudo-Kaposi sarcoma is used to describe 2 variants of acroangiodermatitis:

Mali-type acroangiodermatitis is more common and is associated with chronic venous hypertension, whereas Stewart-Bluefarb type acroangiodermatitis is less common SBS and is associated with arteriovenous malformations or iatrogenic arteriovenous fistulas (Chea EPet al. 2019).

In chronic venous insufficiency: acroangiodermatitis

More rarely in AV shunts ( Klippel-Trénaunay-Weber syndrome), haemodialysis patients,: Stewart-Bluefarb syndrome

In exceptional cases in paralytic extremities, amputation stumps

In obesity (diagnosis of exclusion).
