Introduction: A keratocystic odontogenic tumor is a benign intra-bone mass originating from dental lamina or its residue. It represents 2–11% of jaw cysts, and has a slow but aggressive growth. The evaluation of molecular characteristics, immunohistochemistry, and genetic expression currently have no established classification regarding the evolution and pathophysiologic pattern of these lesion...

Giant cell tumor (GCT) of the bone also known as osteoclastoma typically arises from meta-epiphyseal region long and comprises 5% all tumors 20% benign tumors. Understanding pathogenesis is key to successful systemic therapy with denosumab, a RANK-ligand inhibitor. In this context, we report seven GCT bone-treated denosumab radiotherapy cases diverse clinical presentation our institute, NRS Med...

Primary bone tumors can be either benign or malignant considering their natural history and cellular morphology. Benign bone tumors are much more frequent than malignant ones although some of them like giant cell tumor of bone can behave just like a malignant one that means has the capacity for massive local destruction and remote metastasis. Giant cell tumor of bone in adult people has a very ...

The diagnosis of a bone tumor in a child can be a source of great anxiety for the patient, the parents, and the treating physician. Fortunately, most bone tumors in children are benign. Although there are a variety of benign bone tumors that affect skeletally immature patients, most have such characteristic clinical and radiographic presentations that the diagnosis can be made with reasonable a...

Osteoid osteoma is a benign bone tumor that when located on the base of the coracoids process of the scapula is very rare and diagnosis and treatment is often delayed because of its rarity. Almost any bone can be involved, but half of cases involve the femur or tibia. The radiologic features of osteoid osteoma are well known, but these tumors may present with unusual features and be easily misd...

Background: Subungual exostosis is a relatively uncommon, slow-growing benign bone tumor that most often affects the toes of young people and has significant impact on quality life. The treatment which essentially based surgical excision with meticulous closure wound while avoiding causes nail dystrophy.

normal 0 false false false en-us x-none ar-sa unicameral bone cysts (ubcs) are benign, osteolytic lesions which are often asymptomatic and are commonly seen in the proximal of humerus and femur. the average age at diagnosis is 9-11 years and there is a male preponderance with a male-to-female ratio of approximately 2-2.5 to 1. we describe a case of 5-year-old girl who presented to orthopedic cl...

giant cell tumors (gct) are benign tumors with potential for aggressive behavior and capacity to metastasize. although rarely lethal, benign bone tumors may be associated with a substantial disturbance of the local bony architecture that can be particularly troublesome in peri-articular locations. its histogenesis remains unclear. it is characterized by a proliferation of mononuclear stromal ce...
