Pseudo-Kaposi sarcoma in scar: A case report

"nPseudo-Kaposi sarcoma (PKS) or acroangiodermatitis is a benign angioproliferative disease which shares many clinical and histopathological features with Kaposi sarcoma. Clinical presentations include violaceous macules, papules or plaques in the lower extrimities, which is usually associated with chronic venous insufficiency or congenital or acquired arterio-venous malformations. Its pathogenesis is not well recognized yet but the ischemia due to venous insufficiency or arterio-venous malformation is considered to play a role. The diagnosis is made through the histopathologic examination of biopsy specimens. Different treatment modalities have been suggested including conservative treatment or correction of vascular abnormalities."nThis paper introduces a 28-year old man with a brown linear plaque in a scar of 3-month duration due to trauma on the anterior of left thigh. A biopsy was performed and the histopathologic examination confirmed the clinical diagnosis of Pseudo-kaposi sarcoma.
