Resumen (ES)
Diagnosis of osteosarcoma presents specific problems. In fact, several and different
varieties, presenting different prognosis and requiring different treatments, have to be recognized.
Moreover, the adoption of new therapeutic protocols including preoperative chemotherapy, requires
a careful histopathological evaluation of the specimen to quantify the chemotherapy-induced necrosis
and the surgical margins. This paper analyzes the different histopathological varieties and problems
related to the evaluation of the effects on the resected specimen of preoperative chemotherapy.
