conclusion:
In brief, our case illustrates the difficulties in distinguishing primary bone lymphoma from osteomyelitis as both have similar presentations, while the radiologic findings can overlap and mimic one another.
Our experience with this case emphasizes the fact that for an accurate diagnosis while the clinical manifestations and Para clinical findings are suggestive for malignancies and tumors, in this case, lymphoma, and the results from core needle biopsy are incoherent, open biopsy is to be considered.
