INTRODUTION

Tumor-like bone lesions (TLBL) are non-neoplastic conditions that simulate bone tumors,1 due to clinical findings and appearance on imaging. It is important to recog- nize them because they may be confused with true bone neoplasms and eventually receive excessive or inadequate orthopedic treatment.1

The differential diagnosis is wide, and it is important to rule out other patholo- gies.2 Adequate history and physical examination, associated with plain radiographs and, eventually, advanced imaging methodologies usually lead to a diagnosis;2 even- tually, an excisional biopsy may be necessary for definitive diagnosis.2

TLBL occur so often in the age group between five and 25 years, in sites with higher bone growth, with 60% of the cases located around the knee.1 TLBL located in the upper limbs may present symptomatically or asymptomatically,1 which may cause fractures, deformities, discrepancy in member length, functional limitation and disability.1

The goals of treatment of TLBL in the extremities are to reduce pain, optimize function and prevent local recurrence. Due to the diversity of conditions treated by the orthopedic oncologist, treatment is individualized in all cases.3 The treatment of these lesions has presented recent and continuous innovations, such as the use of new drugs and modalities of adjuvants and bone substitutes, in addition to advan- ced techniques of surgical approach,1 regarding the accesses (minimally invasive) and equipment used.
