Pseudo-Kaposi sarcoma. A patient with arteriovenous malformation and skin lesions simulating Kaposi sarcoma

Vascular malformations

“…Skin changes mimicking Kaposi sarcoma, known as Stewart-Bluefarb syndrome, may develop in lower extremity AVMs. [75][76][77][78][79] Conversely, Kaposi sarcoma may be misdiagnosed as an AVM. 80 Advancement to this stage is commonly induced by puberty, trauma, and pregnancy.…”

Case report Acroangiodermatitis (Pseudo-Kaposi's sarcoma); A challenging vascular condition

“…Thus, they proposed the designation of "pseudoKaposi's sarcoma". 5 In 1982, Brenner et al published a study entitled "Kaposi-like arteriovenous malformation and Angiodermatitis". 6 Strutton and Weedon applied the designation of "Acroangiodermatitis".…”

Acroangiodermatitis in a leg amputee using a suction-socket prosthesis: clinical, histological as well as HHV-8 and CD34 immunohistochemical study

“…Acroangiodermatitis (pseudo-Kaposi sarcoma, AAD) is a rare, chronic vascular phenomenon of unclear pathogenesis described by Mali et al in 1965 [1,2]. The disease might be congenital, yet in acquired form chronic venous insufficiency and vascular anomalies seem to be an underlying background for proliferation of preexisting blood vessels.…”

“…Although vascular hyperplasia, blood extravasation leading to hemosiderin deposition and inflammatory infiltration are features of both AAD and Kaposi sarcoma (KS), both entities remain unrelated, despite the fact that a relationship might be suspected on the basis of misleading nosology proposed by Earhart et al [2]. Kaposi sarcoma is a progressive cancer of endothelial origin that may imitate AAD clinically and even histopathologically.…”
