Hiperplastik kallus formasyonu: erişkin hastada nadir bir vaka

Hyperplastic callus formation is a rare condition that may occur in patients with impaired fracture healing. It is important for the differential diagnosis of malignancies such as osteosarcomas and chondrosarcomas. Some case reports in the literature were misdiagnosed as osteosarcoma, especially in pediatric patients with osteogenesis imperfecta. Here, we present the case of an adult patient with osteoporosis. Cross-sectional imaging showed a mass that had destroyed the bone cortex with soft tissue components and with mineralized matrix in the right superior and inferior pubic rami. The radiological diagnosis was chondrosarcoma, and the mass was completely removed. The patient was diagnosed with a hyperplastic callus that had developed due to osteoporosis.
