In this young, female patient with left-knee pain associated with a cartilaginous lesion of benign appearance, the relatively rare juxtacortical location, with associated cortical break, raises concern for a low-grade cartilaginous malignancy, such as a juxtacortical chondrosarcoma as opposed to the benign juxtacortical chondroma.
Clinically, presentation of a juxtacortical chondroma may be with a firm, nonmobile, slowly growing, palpable mass that may have pain that increases with lesion size.
