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.
血管内乳头状内皮增生（IPEH），也称为马松瘤，是一种良性的罕见血管病变，被认为起源于机化血栓。在组织学上，IPEH的特征是由增生的内皮细胞排列的乳头状叶，可能会模仿血管肉瘤，因此正确的诊断可以避免不必要的根治性手术。膀胱受累极为罕见，文献中仅报道了3例。我们报告1例发生于1例有前列腺癌放疗史患者膀胱的IPEH。
