Typically, this lesion affects adolescents and young adults and presents as a swollen, painful, and erythematous finger or toe. Spjut and Dorfman reported that the lesion appears benign radiographically but could be mistaken for a variety of malignant lesions, especially osteosarcoma, on histological examination13. Magnetic resonance imaging scans often demonstrate massive signal changes within the soft tissue that are consistent with infection, trauma, or a tumor of the soft tissue or bone. We report the case of a five-year-old girl who was followed clinically and radiographically after the diagnosis of florid reactive periostitis ossificans involving the proximal aspect of the tibia. To our knowledge, we are the first to . . . [Full Text of this Article]
