Bilateral Pseudo-Kaposi Sarcoma in Upper Limbs

Diffuse dermal angiomatosis: a contributory factor to ulceration in a patient with renal transplant

“…Indeed, the vascular proliferation seen here mimics acroangiodermatitis, which usually refers to skin changes in the lower leg of patients with severe and long‐standing venous insufficiency . Similar changes have also been described with congenital and surgically formed AV fistulas . However, the classic features of acroangiodermatitis, with red blood cell extravasation and haemosiderin deposition, were not convincingly seen in our case.…”

Case of bilateral acroangiodermatitis due to symmetrical arteriovenous fistulas of the soles

“…PubMed search using the terms "acroangiodermatitis", "pseudo-Kaposi sarcoma", "bilateral" and "both legs" revealed several reports of bilateral cases, but they were due to exacerbated stasis dermatitis, 6 vein harvest 7 or arteriovenous shunts from hemodialysis. 8 This is the first case of bilateral acroangiodermatitis due to symmetrical arteriovenous fistulas. The small size of the symmetrical arteriovenous fistulas suggests that these are congenital malformations.…”

“…Because of the organic disorder of the vasculature, this skin disturbance generally presents with unilateral lesions. A PubMed search using the terms “acroangiodermatitis”, “pseudo‐Kaposi sarcoma”, “bilateral” and “both legs” revealed several reports of bilateral cases, but they were due to exacerbated stasis dermatitis, vein harvest or arteriovenous shunts from hemodialysis . This is the first case of bilateral acroangiodermatitis due to symmetrical arteriovenous fistulas.…”

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

“…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. The AAD was reported in patients with paralyzed limbs [3], hemodialysis patients with arteriovenous shunts [4] or after minor trauma [5] as well as in amputees with suction-socket prostheses [6,7].…”

“…Regardless of histopathological features that may be utilized to distinguish these angioproliferative disorders (a lobular arrangement of blood vessels with thick walls and "chubby" endothelial cells, absence of cell atypia and lesser inflammatory infiltrate that is generally poor in plasma cells in AAD), immunostaining for the CD34 antigen as well as tissue, most importantly, and blood studies for Kaposi's sarcoma-associated herpesvirus (HHV-8) were adopted to differentiate these entities of significantly distinct prognosis [8][9][10]. Other methods of distinction may be CD31-immunolabelling, endothelial cell markers UEA-1 and factor VIII, or radiological imaging (ultrasonography, Doppler ultrasound, magnetic resonance tomography, computed tomography, angiography and phlebography) [4,[11][12][13]. The first suctionsocket prosthesis was invented by Dubois D. Parmelee in 1863.…”
