摘要
Aneurysmal bone cyst (QOA) is a benign bone tumor consisting of blood-filled cavities lined by connective tissue septa. The known association with other neoplastic lesions QOA and the difficulty of differential diagnosis, requiring the comprehensive study on histological examination of the material obtained by curettage and a close radiological monitoring. We report for their rarity and diagnostic difficulty, a case of telangiectatic osteosarcoma (OT) located in the femur in a patient with a history of QOA. There is no report of this kind in our country. We describe a patient who developed an OT at the site of a previously treated QOA after obtaining complete curettage and bone grafting of the cyst. We describe the clinical, radiographic and light microscopy. The development of this case illustrates the great difficulty in differentiating a QOA of OT. In these cases the clinical course can be directed to more appropriate behavior, without being over treated a benign lesion or let a malignancy lesion without treatment. Little is known about the time from the origin of osteosarcoma at the time of clinical manifestation in this case was preceded by a QOA but we cannot ensure that the tumor was not present from the start. One cannot exclude the possible alternative of aneurysmal bone cyst was transformed into a malignant lesion.
