摘要
Abstract
Reactive lesions of bone and soft tissue can appear alarming on histologic examination because they are often cellular and have atypical cytologic features, such as distinct nucleoli, mild hyperchromasia, and mitotic activity. Reactive lesions of bone and periosteum also produce bone and cartilage matrix, resulting in confusion with osteosarcoma or chon-drosarcoma. Careful attention to key cytomorphological features such as the pattern of bone formation, uniform appearance of cells, and absence of atypical mitoses should help identify the reactive nature of a lesion. Correlation with clinical and radiological findings is also imperative to avoid misclassification of the tumor because reactive lesions often arise at sites where osteosarcoma and chondrosarcoma are rare (eg, the hand) and lack aggressive radiological features. Here we pres-ent a case of exuberant callus formation after avulsion fracture of tibia in a three year-old Iranian girl which misdiagnosed as osteosarcoma. 关键词
