It frequently causes pain that is worse at night and is exquisitely responsive to nonsteroidal anti-inflammatory drugs (NSAIDs).Nonossifying fibromas (NOFs) are common fibrous lesions. They are often incidental findings but can also cause chronic pain.Osteochondromas tend to present as a bony, nonpainful mass. Radiographically they appear as sessile or pedunculated lesions of the long bones.Patients with enchondromas may present with a mass or pathologic fracture but most are asymptomatic. The hands are most commonly involved.Solitary bone cysts in the lower extremity are prone to fracture and require excision.Aneurysmal bone cysts (ABCs) commonly involve the long bones. They are associated with rapidly progressive pain and swelling and can cause significant morbidity.
