Histological studies showing the presentation of the recurrent lesion and the result of treatment after the last operation. (a) Magnetic resonance imaging scan reveals the recurrent tumor mass at the right tibial metaphysis. (b) A histological section of the recurrent tumor displaying nests and cords (arrow) of atypical cells, mimicking the features of the primary lesion in Figure 1c (hematoxylin and eosin stain; original magnification, ×400).
