The first case of benign fibrous histiocytoma of the renal capsule is reported in a male aged 44 years. The tumor had its point of origin in the renal capsule. Histologically, the tumor was composed of intersecting fascicles of fibroblastic cells forming a loose crisscross or "storiform" pattern. Electron microscopic studies of tumor cells revealed intermediate filaments and membrane-bound collagen fibers which continued to extracellular collagen bundles. This deep seated fibrous histiocytoma had a more prominent storiform pattern and fewer secondary elements such as xanthoma cells than cutaneous ones.
报告了首例发生于一名44岁男性肾包膜的良性纤维组织细胞瘤。肿瘤起源于肾包膜。组织学上，肿瘤由成纤维细胞相互交叉的束状结构组成，形成疏松的十字交叉或“车辐状”图案。对肿瘤细胞的电子显微镜研究显示，中间丝和膜结合胶原纤维延伸至细胞外胶原束。这种深部纤维组织细胞瘤的车辐状图案比皮肤型更明显，黄色瘤细胞等次要成分较少。
