BACKGROUND Vascular tumors of the kidney are rare tumors that are usually diagnosed and confirmed by histopathological examination due to the difficulty in definitive diagnosis by clinical and radiological examination. Anastomosing hemangioma is a rare variant of capillary hemangioma that mimics angiosarcoma. CASE REPORT Here, we present a case of a 55-year-old female with a history of partial nephrectomy due to clear cell renal cell carcinoma three years earlier, who presented with a contralateral anastomosing capillary hemangioma. The diagnosis was confirmed by histopathology and immunohistochemistry studies. CONCLUSIONS Anastomosing hemangioma is a rare variant of capillary hemangioma. It has a sinusoidal growth pattern which resembles splenic parenchyma. It mimics malignant neoplasms, thus, clinical and radiological examination are not enough for accurate diagnosis. In this paper, we discuss the most crucial differential diagnoses and the pitfalls in diagnosing this rare variant of hemangioma. Furthermore, we present a literature review of all cases reported in the English-language literature.
背景 肾血管肿瘤是罕见肿瘤，由于临床和放射学检查难以明确诊断，通常需经组织病理学检查来确诊。吻合性血管瘤是毛细血管瘤的一种罕见变异型，可酷似血管肉瘤。病例报告 在此，我们报告一例55岁女性患者，3年前因透明细胞肾细胞癌行部分肾切除术，现发现对侧有吻合性毛细血管瘤。诊断经组织病理学和免疫组织化学研究得以证实。结论 吻合性血管瘤是毛细血管瘤的一种罕见变异型。它呈窦状生长模式，类似脾实质。它酷似恶性肿瘤，因此临床和放射学检查不足以准确诊断。在本文中，我们讨论了诊断这种罕见血管瘤变异型的最关键鉴别诊断及陷阱。此外，我们还对英文文献报道的所有病例进行了文献综述。
