%X <strong><span style=\"font-family:Verdana;\">Introduction:</span></strong><span><span style=\"font-family:;\" \"=\"\"><span style=\"font-family:Verdana;\"> Osteosarcoma is the most common primary malignant
bone tumor in children. It is highly aggressive and has a poor prognosis. A
late presentation modifies and makes difficult the management affecting the
survival of children. We report the case of a large conventional osteosarcoma
in a 13-year-old girl. </span><b><span style=\"font-family:Verdana;\">Case Presentation:</span></b><span style=\"font-family:Verdana;\"> Adolescent girl admitted for
painful swelling of the left shoulder with absolute functional impotence of the
thoracic limb and severe anemia. The painful swelling was thought to have been
caused by a minor trauma that had occurred six months previously. The pat</span><span style=\"font-family:Verdana;\">ient¡¯s general condition was poor, and she
presented with a large, shin</span><span style=\"font-family:Verdana;\">y, painful mass over the shoulder and upper
2/3 of the left arm, measuring 28 cm long by 28 cm wide and 57 cm in circumference,
and a large fistulous axillary adenopathy. CT scan showed a tumour lesion of
the left humerus with liver and lung metastases, raising suspicion of
osteogenic osteosarcoma. The tumor was classified according to TNM staging:
T2N1M1(a</span></span></span><span><span style=\"font-family:;\" \"=\"\"> </span></span><span style=\"font-family:Verdana;\"><span style=\"font-family:Verdana;\">+</span></span><span><span style=\"font-family:;\" \"=\"\"> </span></span><span><span style=\"font-family:;\" \"=\"\"><span style=\"font-family:Verdana;\">b). Management was modified when uncontrolled bleeding developed. It
consisted of an extended amputation of the left thoracic limb. Pathological
analysis showed a high</span><span style=\"font-family:Verdana;\">-grade conventional
osteosarcoma. Quality improvement was obtai</span><span style=\"font-family:Verdana;\">ned for thirty days, followed
by the onset of dyspnea. The evolution was towards death at forty days
post-operatively. </span><b><span style=\"font-family:Verdana;\">Conclusion:</span></b><span style=\"font-family:Verdana;\"> Osteosarcoma is a highly aggressive
cancer. Delayed treatment leads to a fatal outcome. Early diagnosis is one of
the challenges to be met in order to improve survival.</span></span></span>
