Chondromyxoid fibroma is a relatively rare benign bone tumor whose histologic and radiologic patterns are well known. In this article, we describe a 16-year-old boy with such a tumor in his left tibia. Scintigraphically, this tumor is represented by a "doughnut sign". This aspect, though not pathognomonic, has been reported sporadically in a few diseases: osteoporosis circumscripta cranii, angioblastic meningioma, cranial coccidioidomycosis, and aseptic necrosis of frontal bone. Because of their sites, it is easy to reject these diagnoses in our patient. The most pertinent differential diagnosis with regard to the clinical, radiological, and scintigraphic aspects in the patient is that of a giant cell tumor.

Chondromyxoid fibroma (CMF) in the foot is a rare condition. We report a case of CMF in a 7-year-old girl, affecting the distal phalanx of the great toe. Radiographs revealed a lytic lesion involving the entire distal phalanx, with destruction of both the medial and lateral cortices, while the articular surfaces remained intact.

Background: Benign bone lesions are a common incidental finding in athletes during workup for musculoskeletal complaints, and athletes are frequently advised to halt participation in contact sports. There are no current guidelines to assist clinicians in referring patients with these lesions to a subspecialist or in advising athletes on the safety of returning to sport.
Purpose: To assist sports medicine physicians in appropriate referral for patients with benign bone lesions through presentation of a literature review and the case of an adolescent athlete with a benign bone lesion in a location with a significant fracture risk.
