[Bilateral pseudo-Kaposi sarcoma in upper limbs].
Acroangiodermatitis or pseudo-Kaposi sarcoma is an angioproliferative, self-limited entity that includes a group of diseases, congenital or acquired, with cutaneous lesions similar to Kaposi sarcoma (KS). This term can lead to confusion because it comprises several entities that are completely different, nonetheless, it has an important clinical value as it guides the diagnosis and management of these patients. We report the case of a 67-year-old patient with lesions of acroangiodermatitis in both forearms secondary to arteriovenous shunts from hemodialysis. Doppler ultrasound showed a former arteriovenous fistula in addition to the one already known. Immunohistochemical study showed CD34+ staining in endotelial cells and absence of HHV-8 expression.
