A desmoplastic fibroma of the left humerus with a pathological fracture in a 9-year-old girl is presented. The postoperative course was uncomplicated: no recidive occurred. The histological picture of this rare bone tumor (76 similar cases were reported in the literature) is identical both with aggressive fibromatosis and with the desmoid tumor. It contains areas with abundant collagen fibers and densely packed areas composed of fibrocytes, fibroblasts as well as myofibroblasts. Myofilaments have been detected by electron microscopy in the latter cell type.
本文报道了一名9岁女孩左肱骨促纤维组织增生性纤维瘤合并病理性骨折的病例。术后过程顺利：未出现复发。这种罕见骨肿瘤（文献报道过76例类似病例）的组织学表现与侵袭性纤维瘤病和硬纤维瘤相同。它包含富含胶原纤维的区域以及由纤维细胞、成纤维细胞和肌成纤维细胞密集组成的区域。通过电子显微镜在后者细胞类型中检测到了肌丝。
