A vascular tumor is a benign tumor with unique clinical and pathological features. Perirenal vascular tumor is extremely rare and has not yet been reported. Clinically, it manifests as soreness and swelling. Color ultrasound and renal angiography illustrated the perirenal mass, which was closely connected with the kidney and the surrounding tissues and organs. Histology showed extensive embedded perirenal fat, and thin-walled vascular tissue displayed a pink stain due to red blood cells.
Herein, a case of robot-assisted retroperitoneal laparoscopic excision of a perirenal vascular tumor is reported. Analysis of the clinical, biological, and histological features of the perirenal vascular tumor can provide an in-depth understanding of the disease, which provides a theoretical and practical basis for better diagnosis and treatment.
This study contributes to a practical basis for the diagnosis and treatment of perirenal hemangiom.
Core tip: Perirenal vascular tumor is an extremely rare disease. We summarized the clinical manifestations, imaging features, and pathological characteristics of a perirenal vascular tumor in a clinical case, and successfully removed the tumor using robotic surgery without complications. This provides a practical model for the diagnosis and treatment of this disease.
