本文介绍了20例良性骨母细胞瘤的临床和病理资料，迄今为止共观察到31例。这些良性的类骨质和骨形成肿瘤最常见于儿童或青少年，特别是四肢骨、脊柱和颅骨。X线照片可能不够独特，无法进行准确识别。在某些病变中，显微镜下的图像可能类似于骨样骨瘤;在其他病变中，可能有各种其他独特的模式，这已经被阐明。当类骨质形成和骨形成病变在其周围引起明显的反应性骨瘤时，即使它可能比通常的骨样骨瘤大得多，也被称为骨样骨瘤，而不是良性成骨细胞瘤。在这一系列的2例病例中，肿瘤在长骨的表面偏心发展，而不是在内部。这两个肿瘤是不寻常的：他们被暂时解释为良性成骨细胞瘤的骨膜对应物。手术治疗应根据肿瘤的良性性质，采取保守治疗。在脊柱良性骨母细胞瘤的治疗中，侵犯螺旋索或其神经根，外科医生应满足于完成减压，然后立即进行X线照射。
This paper presents clinical and pathological material from twenty additional cases of benign osteoblastoma, making a total of some thirty-one that have been observed to date. These benign osteoid-forming and bone-forming tumors are encounted most often in children or teen-agers, particularly in limb bones, the vertebral column, and the calvarium. The roentgen picture may not be sufficiently distinctive to permit accurate identification. In some lesions, the microscopic picture may resemble that seen in osteoid osteoma; in others, there may be a variety of additional distinctive patterns, which have been illustrated. When an osteoid-forming and bone-forming lesion provokes marked reactive osteosclerosis around it, it is designated as an osteoid osteoma, rather than benign osteoblastoma, even though it may be substantially larger than the usual osteoid osteoma. In 2 of the cases in this series, the tumor developed eccentrically on the surface of a long bone, rather than in the interior. These 2 tumors are unusual: they were interpreted provisionally as the periosteal counterpart of benign osteoblastoma. Surgical treatment shoud be conservative, in keeping with the benign character of the tumor. In the treatment of benign osteoblastoma in the vertebral column, impinging on the spiral cord or its nerve roots, the surgeon should be content to accomplish decompression, promptly followed by roentgen irradiation.
