Pseudo-Kaposi Sarcoma

The development of pseudo-Kaposi's sarcoma after placement of a vascular access graft

“…The presence of nuclear atypia and vascular slits have been thought to distinguish Kaposi's sarcoma from other angiomatous neoplasms (Earhart et al, 1974;Lever & Schaumburg-Lever, 1975); our patient demonstrated both these findings.…”

“…The association of an underlying congenital arteriovcnous malformation with a cutaneous dysplastic angiopathy which may resemble Kaposi's sarcoma, both clinically and histologically, is well known. Stewart & Lauret (1970) and Earhart et al (1974) used the term pseudo-Kaposi's sarcoma to apply to such lesions. Baxt, Mori & Hoffman (1975) reported the development of Kaposi's sarcoma-like lesions 3 years after the appearance of an arteriovenous fistula of the hand.…”

Pseudo‐Kaposi Sarcoma with Arteriovenous Malformation

“…The patient may complain of pain and paresthesias. Histopathologic features include proliferation of small blood vessels and fibroblasts, extravasated erythrocytes, and hemosiderin deposition in the dermis without the characteristic vascular slits of Kaposi sarcoma (6).…”

“…In 1967 Bluefarb and Adams (5) described a patient who had congenital AVM with angiodermatitis that simulated Kaposi sarcoma clinically and histologically, but it was Earhart et al. (6) who proposed the term pseudo‐Kaposi sarcoma.…”

Recurrent Pyogenic Granuloma with Multiple Satellites

“…In recent years special attention has been given to a series of hyperplastic vascular pro cesses ofthe skin, which are of obscure patho genesis and are susceptible of being con fused with malignant vascular tumours: vég étant intravascular haemangioendothelioma or intravascular papillary endothelial hyperplasia [2,3], Kaposi's pseudosarcoma [5], angiolymphoid hyperplasia with eosinophilia [10], intravenous atypical vascular proliferation [13], papular angioplasia [16], atypical pyogenic granuloma [15] and recur rent pyogenic granuloma with multiple sat ellites [1,6,8.12,14, 18,19]. This last entity is one of the rare complications of pyogenic granuloma and usually presents subsequent to surgical extirpation or cauterization of the original lesion.…”
