Arteriovenous malformation simulating Kaposi's sarcoma (pseudo-Kaposi's sarcoma). 1985

M E Marshall, and S T Hatfield, and D R Hatfield

A patient whose condition was initially misdiagnosed as Kaposi's sarcoma involving the left foot received radiation therapy for that disorder. Subsequent examination yielded a correct diagnosis of arteriovenous (AV) malformation. Such cases of AV malformations with skin changes resembling Kaposi's sarcoma have been called pseudo-Kaposi's sarcoma. The clinicopathologic distinctions between Kaposi's sarcoma and pseudo-Kaposi's lesions are discussed. All patients suspected of having Kaposi's sarcoma, especially those younger than 30 years of age, should have careful evaluation for an unsuspected AV malformation.

D001158	Arteries	The vessels carrying blood away from the heart.	Artery
D001165	Arteriovenous Malformations	Abnormal formation of blood vessels that shunt arterial blood directly into veins without passing through the CAPILLARIES. They usually are crooked, dilated, and with thick vessel walls. A common type is the congenital arteriovenous fistula. The lack of blood flow and oxygen in the capillaries can lead to tissue damage in the affected areas.	Arteriovenous Malformation,Malformation, Arteriovenous,Malformations, Arteriovenous
D012514	Sarcoma, Kaposi	A multicentric, malignant neoplastic vascular proliferation characterized by the development of bluish-red cutaneous nodules, usually on the lower extremities, most often on the toes or feet, and slowly increasing in size and number and spreading to more proximal areas. The tumors have endothelium-lined channels and vascular spaces admixed with variably sized aggregates of spindle-shaped cells, and often remain confined to the skin and subcutaneous tissue, but widespread visceral involvement may occur. Kaposi's sarcoma occurs spontaneously in Jewish and Italian males in Europe and the United States. An aggressive variant in young children is endemic in some areas of Africa. A third form occurs in about 0.04% of kidney transplant patients. There is also a high incidence in AIDS patients. (From Dorland, 27th ed & Holland et al., Cancer Medicine, 3d ed, pp2105-7) HHV-8 is the suspected cause.
