Large osteosarcoma of the leg: that's about the diagnosis on an eight year old boy in the pediatrics service of local hospital center of Abidjan (Côte d'Ivoire).

Abstract

Background: In pediatric, it is sometimes difficult to differentiate the relapse of primary tumor from other diagnoses such as osteomyelitis, without performing an organ biopsy. In addition, primitive bone cancer represents 6% of children cancer. Etiologies are predominated by the osteosarcoma that represents around 30 - 80% of the original sarcomas of the skeleton. Case presentation: The authors report a case of 8 years old african boy with osteosarcoma. He suffered of a painful tumefaction of the left leg. That was declared since 6 months with the alteration of his general shape. In the beginning of his symptomatology, he was taken in charge by a small town near Abidjan where the osteomyelitis diagnosis was made. He was not only given an antibiotherapy but also his leg was put in plaster. Conclusion: The biopsy osseous performed on a piece representing the histological exam remains the very key of the diagnosis. The association of both the conservative surgery of the limb and the adjuvant chemotherapy allows today to have a reproduction rate of 7%.
