摘　　要：Primary vascular tumours of the kidney are rare and may pose diagnostic difficulties because of their similar clinical,morphological,and immunohistochemical features.This article summarizes the clinical and pathological features of primary renal angiosarcoma and anastomosing haemangioma of the kidney including epidemiology,genetics,and prognosis.Renal anastomosing haemangiomas are benign neoplasms characterized by anastomosing capillary-sized vascular channels.These tumours are rare,with about 75 cases reported in the literature.Most anastomosing haemangiomas are found incidentally on ultrasound,computed tomography,or magnetic resonance imaging.Common symptoms include abdominal pain,haematuria,and abdominal mass.Renal anastomosing haemangiomas are characterized by recurrent mutations in GNAQ and GNA14 genes.The prognosis of anastomosing haemangioma is excellent.Primary renal angiosarcomas are malignant tumours showing endothelial differentiation.To date,76 cases have been described in the literature.Primary renal angiosarcomas are frequently symptomatic.The clinical features of renal angiosarcomas are similar to those of renal anastomosing haemangiomas,including abdominal pain,haematuria,and abdominal mass.Angiogenesis-related genes and vascular-specific receptor tyrosine kinases such as KDR,TIE1,SNRK,TEK,and FLT1 are upregulated in angiosarcomas.Primary renal angiosarcomas are highly aggressive neoplasms with a poor prognosis despite surgical treatment,chemotherapy,radiotherapy,or targeted therapy.
