Bone metastasis, or osseous metastatic disease, is a category of cancer metastases that result from primary tumor invasions into bones.Bone-originating primary tumors such as osteosarcoma, chondrosarcoma, and Ewing sarcoma are rare; the most common bone tumor is a metastasis. [1]
An osteosarcoma (OS) or osteogenic sarcoma (OGS) (or simply bone cancer) is a cancerous tumor in a bone.Specifically, it is an aggressive malignant neoplasm that arises from primitive transformed cells of mesenchymal origin (and thus a sarcoma) and that exhibits osteoblastic differentiation and produces malignant osteoid.
Ischaemic fasciitis, previously termed atypical decubital fibroplasia or decubital ischemic fasciitis, was thought to be a non-neoplastic lesion and to occur only in the deep subcutaneous tissue at pressure points or bone prominences but more recently has been found to be a benign neoplasm that can occur in a wider range of tissue sites. [5] [6]

Multiple myeloma is a hematologic cancer, originating in the bone marrow, which also frequently presents as one or more bone lesions. [10] Germ cell tumors, including teratoma, often present and originate in the midline of the sacrum, coccyx, or both. These sacrococcygeal teratomas are often relatively amenable to treatment. [11]
Plain films add valuable information in the initial evaluation or screening. The wide zone of transition (e.g. permeative) is the most useful plain film characteristic in differentiation of benign versus aggressive or malignant lytic lesions.

On X-ray, giant-cell tumors (GCTs) are lytic/lucent lesions that have an epiphyseal location and grow to the articular surface of the involved bone. [8] Radiologically the tumors may show characteristic 'soap bubble' appearance. [9] They are distinguishable from other bony tumors in that GCTs usually have a nonsclerotic and sharply defined border.
Intra-articular tumors typically occur in the knee (approximately 75% of cases) and hip (approximately 15% of cases). [3]: 102 Extra-articular tumors are usually found in the knee, thigh, and foot. [3]: 101 Symptoms include swelling, pain, sensitivity, and/or limited range of motion.
