ABSTRACT

Primary bone tumors are relatively uncommon, occur at any age, and can be either benign or malignant. Secondary involvement by metastases is more common. In dealing with bone tumors, pathologists need to be familiar not only with the common tumors, but with the rare and unfamiliar tumors and tumor-like conditions. The consequences of a pathological misdiagnosis can be quite drastic to the patient’s management. The key to pathological diagnosis of bone tumors is the knowledge of clinical information and the imaging and X-radiographic findings.
