They can arise from nonneoplastic and neoplastic origin, the latter of which might be malignant. Juxtacortical lesions of neoplastic origin can be categorized into bone-forming lesions, cartilaginous lesions, fibrous lesions, lesions of local vascular or neurogenic origin, or metastatic lesions. Forming a differential diagnosis can be challenging for any physician assistant. We selected a series of cases from our tertiary care clinic that have been subject to discussion for their similarity but vastly different prognosis. Our aim is to provide a rubric to compare juxtacortical lesions with guide orthopaedic and sport medicine providers in determining the immediacy of referral and follow-up.
