Acroangiodermatitis presenting as unilateral hypertrophic verrucous plaques

Dermatol Online J. 2022 Mar 15;28(2). doi: 10.5070/D328257400.

Abstract

Acroangiodermatitis (AAD)[KL1] is a rare vasoproliferative disorder often involving the extremities that has been classified into two variants. Mali-type AAD is more common and associated with chronic venous stasis. Stewart-Bluefarb syndrome[KL2], the other variant, is associated with underlying arteriovenous abnormalities. Mali-type AAD is a relatively benign diagnosis but it may mimic more harmful etiologies such as Kaposi sarcoma both clinically and histologically. A 67-year-old woman with a history of varicose veins, deep vein thrombosis, stroke, and obesity presented to our outpatient clinic with verrucous red-brown papules and plaques on her right lower extremity worsening for three years. Biopsy was consistent with a diagnosis of Mali-type AAD. Providers should be aware of AAD and its variants to accurately differentiate it from more harmful entities.
