Osteoid osteoma: two unusual case reports

Osteoid osteoma is a relatively common bone tumor that is diagnosed easily but requires a high index of suspicion. The increasing percentage of sports-related injuries in podiatrists' offices, including stress fractures, may cause a doctor to overlook the less frequent pathologic fracture. Two case reports of runners with osteoid osteoma in anatomic areas of classic overuse syndrome are described. A review of the diagnosis and treatment follows in an effort to increase awareness that runners do suffer nonmechanical foot disorders.
