Intravascular papillary endothelial hyperplasia of the bladder: Case report and review of the literature

Abstract

Intravascular papillary endothelial hyperplasia (IPEH), also known as Masson's tumor, is a benign unusual vascular lesion thought to arise from an organizing thrombus. Histologically, IPEH is characterized by papillary fronds lined by proliferating endothelium that may mimic angiosarcoma, and therefore the correct diagnosis may prevent unnecessary radical procedures. Involvement of the bladder is extremely rare, with only three cases reported in the literature. We report a case of IPEH arising in the bladder of a patient with history of prostate cancer treated with radiotherapy.

Intravascular Papillary Endothelial Hyperplasia of the Foot

“…The mean age at representation is approximately 40 years. It has been reported in various locations, including the fingers (2), ankle (3), lip (4), buccal mucosa, oral mucosa (5), hypopharynx (6), larynx (6), intestines (7), intracranial (8,9), liver (10), and bladder (11). In the present report, we describe a case of IPEH of the dorsum of the foot.…”

Concomitant Retroperitoneal Intramuscular Hemangioma and Intravascular Papillary Endothelial Hyperplasia: An Unusual Case Report

“…IPEH is usually asymptomatic and often an accidental finding in radiological studies. However, uncommon symptoms resulting from tumor bleeding or peripheral organ compression such as epigastralgia, inguinal pain, low back pain, melena, and hematuria have been reported [7] [8]. No previous published case of a patient presenting with acute sciatica complicated with lumbosacral plexopathy was found in our literature review.…”

Cutaneous Intravascular papillary endothelial hyperplasia – A case series

“…6 Few Case reports of IPEH are available involving head and neck, hand, skull, bladder, liver, uterus, brain and gastrointestinal tract. 1,[7][8][9][10][11] In this series the primary lesions presented as solitary swellings of an average of less than two centimeters as described in literature and all were cutaneous in origin involving head, arm, thigh, finger and anal region lesion.…”
