Myxomas are mesenchymal tumors commonly found in the heart and skin. Renal myxomas are rare, having only been documented 14 times. Our case is a 55-year-old woman who presented to our clinic after a right renal mass was incidentally found on CT. Evaluation with MRI showed a mass that appeared to arise from the supero-medial cortex of the right kidney. As the imaging was concerning for renal cell carcinoma, the patient underwent a partial nephrectomy. Microscopic examination showed a well-circumscribed mass with polygonal to spindle-shaped cells in a granular eosinophilic cytoplasm. Immunohistochemical staining for CD-10, Desmin, HMB-45, and Pankeratin were negative.
黏液瘤是常见于心脏和皮肤的间叶组织肿瘤。肾黏液瘤很罕见，仅有14例病例报道。我们的病例是一位55岁女性，因CT偶然发现右肾肿物后来到我们诊所。MRI检查显示一个肿物似乎起源于右肾的上内侧皮质。由于影像学表现提示肾细胞癌，患者接受了部分肾切除术。显微镜检查显示一个边界清楚的肿物，细胞呈多边形至梭形，胞质呈颗粒状嗜酸性。CD-10、结蛋白、HMB-45和全角蛋白的免疫组化染色均为阴性。
