Intravascular papillary
endothelial hyperplasia of renal vein: report of 2 cases.Arch
Pathol Lab Med. 2005 Apr;129(4):516-9.
Intravascular
papillary endothelial hyperplasia is a benign intravascular process
thought to arise from an organizing thrombus. The lesion may present
clinically as an abnormal mass and, depending on the location, may be
confused with benign or malignant neoplasms. It has been described in
a variety of locations. Involvement of the renal vein by papillary
endothelial hyperplasia is extremely rare, with only 4 cases reported
in the literature. We describe 2 additional cases. In both cases, the
radiologic examination revealed a well-circumscribed mass in the hilar
region of the kidney, which was considered to be a renal neoplasm.
Nephrectomy specimen in each case revealed characteristic features of
intravascular papillary endothelial hyperplasia. It is suggested that
intravascular papillary endothelial hyperplasia should be included in
the differential diagnosis of a hilar renal mass.

papillary endothelial hyperplasia of the hand: a case report and
review of the literature.

Intravascular
papillary endothelial hyperplasia (IPEH) is a rare benign endothelial
proliferation that bears a remarkable resemblance to angiosarcoma. We
report a case of cutaneous IPEH in the thumb of a seven-year old girl
which was successfully treated with excision. The relevant literature
is reviewed and histopathological features, differential diagnosis and
natural history of the lesion are discussed. |
