ALVAREZ LOPEZ, Alejandro; CASANOVA MOROTE, Carlos; GARCIA LORENZO, Yenina  y  RODRIGUEZ RODRIGUEZ, Eugenio. Tumors and pseudotumoral bone injuries in children: A 10-year study. Rev Cubana Ortop Traumatol [online]. 2001, vol.15, n.1-2, pp. 79-83. ISSN 1561-3100.

A descriptive, cross-sectional and retrospective study was conducted among 159 patients at pediatric ages up to 15 years old with 184 tumors and primary bone pseudotumoral injuries. The age group 6-10 predominated with 32 % for males and 14.4 % for females. Males were the most affected with 63.5 %. The metaphyseal zones around the knee were the most frequent localization with 35.2 %, the metaphysis distal from the femur and 16.8 % the metaphysis proximal to the tibia. The osteochondroma prevailed as the most common benign tumor with 79.3 %. The most frequent pseudotoumoral injury was the non-ossifying fibroma with 15.2 %. The commonest malignant tumor was the osteosarcoma with 3.2 %. As regards the biological behavior of the bone tumors stated by Enneking, the active form predominated in 88.1 % of the cases, whereas it was observed a predominance of high degree osteosarcoma among the malignant tumors. The lung was the organ with the highest incidence of metastasis. Survival up to 5 years was 33.3 %.
