Intravascular papillary endothelial hyperplasia and osteoma: a case
report of an individual with 2 different pathologies.Quintessence
Int. 2007 Feb;38(2):e88-91.
Intravascular
papillary endothelial hyperplasia (IPEH) is an unusual, benign, non-neoplastic,
vascular lesion characterized histologically by papillary fronds lined
by proliferating endothelium. Osteoma is a benign osteogenic lesion
characterized by proliferation of compact or cancellous bone. Osteoma
of the maxillary sinus is an uncommon lesion. The purpose of this
report is to present a case with 2 different lesions (intravascular
papillary endothelial hyperplasia and osteoma) occurring at the same
time in 1 patient that may or may not be related to each other and to
stress the value of diagnostic imaging.
Intravascular
papillary endothelial hyperplasia of the jejunum: an unusual cause of
melena.Int
J Surg Pathol. 2007
Apr;15(2):192-5.
Intravascular
papillary endothelial hyperplasia is considered to be an unusual form
of thrombus organization that is marked by an excessive papillary
endothelial proliferation. This lesion has the propensity to occur in
the skin and the subcutis. Occurrence in the gastrointestinal tract is
very rare. The authors report an exceptional case of a 20-year-old
young woman with intravascular papillary endothelial hyperplasia in
the jejunum. The patient was referred to the hospital with a 1-week
history of melena. The lesion did not recur after surgery.
Histopathological examination revealed a papillary endothelial
hyperplasia with an underlying arteriovenous malformation. |
