First described in 1965 by Mali et al., pseudo-Kaposi sarcoma (PKS), also known as acroangiodermatitis, is a rare disease inscribed in the setting of cutaneous reactive angiomatoses (CRAs). CRA are all characterized by occlusion and/or inflammation of cutaneous vessels, followed by histiocyte recruitment and endotheliocyte and pericyte hyperplasia. As the name suggests, PKS nearly resembles Kaposi sarcoma, but is benign in its nature. PKS typically presents with violaceous papules and plaques, usually located on the inferior limbs.
