In 1948, Steiner performed an analysis of cancer registries in the United States of America, estimating that primary bone tumors constituted approximately 1% of malignant fetal tumors. A similar incidence of primary bone tumors was observed in Great Britain, ranging from 0.

8% to 0. 9%.

A later statistic from the United States in v of 1. 87:1000 000 among children under 14 years of age, auamento to 11.

97:1000 000 deaths in persons aged 11 to 19 years. Since all bone components are derived from the mesoderm and have the potential to be composed of any of the four basic cell types: fibroblasts, chondroblasts, osteoblasts and the reticulo-myelogenous series, a correct diagnosis requires complementary radiologic and pathologic backdrops as well as biochemical and hematologic investigations.

The present research was focused on a retrospective, observational, quantitative, risk-free, quantitative study, based on the review of files and histological reports of patients who were treated at the Hospital de especialidades "Ignacio García Téllez" CMN IMSS. .
