Osteoid osteoma is a benign bone tumor, which represents approximately 10% of all benign bone tumors. When localized to the carpus, osteoid osteomas are most often seen in the scaphoid and capitate. Rarely, these tumors can also be observed in the trapezium. Given the infrequency with which osteomas are located in the trapezium and often nonspecific presenting symptoms, diagnosis of this tumor ...

The learning objectives of this review article are to identify benign vs. malignant criteria in bone tumor diagnosis and also to differentiate the types of bone tumors and their characterization. Based on the Lodwick classification an overview of the three main types of bone destruction patterns visible on radiographs will be given with many examples. Typical examples of benign and malignant bo...

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 Although primary bone tumors are relatively uncommon, they constitute the most important tumors in patients less than 20 years. We aimed to determine the frequencies of primary bone tumors and tumor-like lesions of bone and the anatomical sites of their occurrence. METHODS A retrospective review of histopathology reports of all bone specimens received in a private pathology laborat...

Desmoplastic fibroma is a rare benign primary bone tumor that is histologically similar to the soft tissue desmoid tumor. It most often involves the mandible, large long bone or iliac bone. Desmoplastic fibroma in a toe has been extremely rarely reported. Authors report a rare case of desmoplastic fibroma of bone occurring in the distal phalanx of a foot, with descriptions of the radiographic a...

To date, there are still very few reports on benign-tumor cases based on East Asian skeletal series, even though other regions and continents have been well represented. In our study on the Joseon Human Skeletal Series, we identified benign bone tumors in two skeletons (cases Nos. 75 and 96). Our radiological analyses showed both cases to be homogeneous sclerotic bone masses aligned with the cr...

Background: Bone tumors are infrequently encountered disease constituting only 0.5% of the total world cancer incidence. There worldwide variations in different bone lesion and patterns cancer. Histologic evaluation is one first prerequisites evaluating any primary tumor. Methods: The present study was carried out at Gauhati Medical College hospital (GMCH), Guwahati, Assam for a period 2 years....

Chondromyxoid fibroma (CMF) is a rare benign cartilaginous tumor with a predilection for the bones of lower extremities and about one fourth of the tumors involve the foot. Radiologically, an eccentric lytic lesion with well-defined margins is seen in the metaphysis of the bone. We hereby, report an 18 yr old young male who presented to Orthopedic Outpatient Department, JN Medical College, Alig...

Benign primary bone tumors are commonly treated with intralesional curettage with or without the use of surgical adjuvants. The reconstructive approach to the resulting contained bone defects is controversial, and clinical practice is varied. Synthetic bone substitutes may provide early mechanical support while minimizing the risks of disease transmission, nonunion, infection, and donor-site mo...
