1. Primary reticulum-cell sarcoma of bone arises from the reticulo-histiocytic elements of bone marrow. 2. The authors have studied ten cases of primary reticulum-cell sarcoma of bone, and have compared the clinical, pathological and radiographic features with those of thirty-five cases of Ewing's sarcoma. 3. In their microscopic studies Hortega's staining techniques were used in addition to orthodox methods. 4. There are histological differences between a reticulum-cell sarcoma and Ewing's sarcoma. 5. Certain clinical and radiographic features help the differentiation between the two tumours. 6. The progress and treatment of the reticulum-cell sarcoma are reviewed in detail.
