Hereditary multiple osteochondromas (HMO), also known as hereditary multiple exostoses, is a disorder characterized by the development of multiple benign osteocartilaginous masses (exostoses) in relation to the ends of long bones of the lower limbs such as the femurs and tibias and of the upper limbs such as the humeri and forearm bones.
Head and neck cancer is a general term encompassing multiple cancers that can develop in the head and neck region. These include cancers of the mouth, tongue, gums and lips (oral cancer), voice box (laryngeal), throat (nasopharyngeal, oropharyngeal, hypopharyngeal), salivary glands, nose and sinuses. [5] Head and neck cancer can present a wide ...
Ewing sarcoma is a type of pediatric cancer [ 5 ] that forms in bone or soft tissue. [ 1 ] Symptoms may include swelling and pain at the site of the tumor, fever, and a bone fracture. [ 2 ] The most common areas where it begins are the legs, pelvis, and chest wall. [ 4 ]
A non-ossifying fibroma (NOF) is a benign bone tumor of the osteoclastic, giant cell -rich tumor type. [1] It generally occurs in the metaphysis of long bones in children and adolescents. [2] Typically, there are no symptoms unless there is a fracture. [2] It can occur as part of a syndrome such as when multiple non-ossifying fibromas occur in ...
Metaphysis. The metaphysis (pl.: metaphyses) is the neck portion of a long bone between the epiphysis and the diaphysis. [1] It contains the growth plate, the part of the bone that grows during childhood, and as it grows it ossifies near the diaphysis and the epiphyses. The metaphysis contains a diverse population of cells including mesenchymal ...
Sebaceous carcinoma is a neoplastic growth of sebaceous glands. It is predominantly seen in the head and neck region given the high density of sebaceous glands in this region. The periocular region, which includes the meibomian, Zeis, and sebaceous glands of the caruncle and eyelid, is the most common site accounting for up to 75% of SGc. [6]
Common [4] A bone tumor is an abnormal growth of tissue in bone, traditionally classified as noncancerous (benign) or cancerous (malignant). [1][4] Cancerous bone tumors usually originate from a cancer in another part of the body such as from lung, breast, thyroid, kidney and prostate. [1] There may be a lump, pain, or neurological signs from ...
A bone scan or bone scintigraphy / sɪnˈtɪɡrəfi / is a nuclear medicine imaging technique of the bone. It can help diagnose a number of bone conditions, including cancer of the bone or metastasis, location of bone inflammation and fractures (that may not be visible in traditional X-ray images), and bone infection (osteomyelitis).
