Osteopoikilosis is a benign, autosomal dominant skeletal dysplasia that manifests radiographically as multiple bone islands which are especially seen near the joints, epiphyses, metaphyses of long and short tubular bones. The condition is also known as the spotted bone. The islands are also seen in in the pelvis and scapulae. The distribution is typically bilateral […]

Bone Island or Enostosis
A bone island or enostosis is a common benign bone lesion. It is asymptomatic and does not require treatment. It is usually seen as an incidental finding on x-ray, computed tomogram and MRI. A bone island is a focus of mature cortical bone within the cancellous bone. Pelvis, femur, and other long bones are the […]
Metastatic Bone Disease
A metastatic bone disease is said to occur when metastases spread to the bone. After lung and liver, bone is considered to be the third most common organ involved by metastases. In breast cancer, the bone is the second most common site for metastases. Metastases in bone need early detection and aggressive management. Aims of […]
What is Metastasis Process and Its Routes
The term metastasis refers to the spread of the cancer cells from their original or primary site to a different location in the body. It must be stressed that local invasive growth is not considered metastases but local spread or expansion of the tumor. Thus metastasis is the process by which cancer cells migrate throughout […]
Osteochondroma and Multiple Hereditary Exostoses
Osteochondroma is a cartilage-capped bony projection on the external surface of a bone and is considered a non-neoplastic anomaly similar to hamartoma. It can occur as a solitary lesion or as multiple hereditary exostoses associated with anomalies of skeletal modeling. Solitary osteochondroma is a developmental anomaly of bone that results in the formation of an […]
Osteoid Osteoma Diagnosis and Treatment
Osteoid osteoma is a benign [non-cancerous] osteoblastic tumor. It was first described by Bergstrand 1930 but its unique identity was recognized by Jaffe in 1935. Osteoid osteoma consists of osteoblastic [growing cells] mass called a nidus [very rich in blood supply]. Nidus is surrounded by a zone of sclerotic but otherwise normal bone. It is a […]
