Lesions typically arise in vascular regions of the head and neck or extremities, but involvement of other organ systems has been reported. Clinically, IPEH mimics other benign lesions (hemangiomas) and malignant neoplasms (angiosarcoma) depending on the affected site. Diagnosis is essential because local excision of certain IPEH subtypes is curative. IPEH in the gastrointestinal tract is rare with few reported cases. We present a case of obscure-overt gastrointestinal bleeding from IPEH of the jejunum.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.14309\/crj.2017.80","type":"journal-article","created":{"date-parts":[[2017,6,27]],"date-time":"2017-06-27T10:55:43Z","timestamp":1498560943000},"page":"e80","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":5,"title":["Intravascular Papillary Endothelial Hyperplasia of the Jejunum as a Cause of Obscure-Overt Gastrointestinal Bleeding"],"prefix":"10.14309","volume":"4","author":[{"given":"Jonathan","family":"Gotfried","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raul Berio","family":"Dorta","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jennifer","family":"Maranki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"issue":"6","key":"R1-80-20260710","doi-asserted-by":"crossref","first-page":"539","DOI":"10.1097\/00000372-198312000-00004","article-title":"Intravascular papillary endothelial hyperplasia: A clinicopathologic study of 91 cases.","volume":"5","author":"Hashimoto","year":"1983","journal-title":"Am J Dermatopathol"},{"issue":"1","key":"R2-80-20260710","first-page":"139","article-title":"Arteriovenous malformation associated with intravascular papillary endothelial hyperplasia in jejunal region.
