3 nosed lesions are best divided into biologically aggressive or nonaggressive categories. Biopsy is indicated if the lesion is aggressive. Otherwise, watchful waiting with follow-up imaging can be pursued. Aggressive features are detected on radiographs by evaluation of imaging characteristics, such as the appearance of the margin, cortical expansion, and periosteal reaction. Clinical examination findings, such as pain, are also contributory.
