osteoblastoma is a rare benign, but locally aggressive bone tumor with rare malignant transformation. it mostly affects the vertebral column and long bones. radiographically, it is seen as an expansile, oval, sclerotic or lytic mass-like lesion with well-defined borders, although sometimes it may mimic a malignant tumor such as osteogenic sarcoma by its irregular borders. herein, we report a ca...

Fibro-osseous lesions of the maxillofacial bones should be classified based on their radiographic growth pattern. This method can simplify this category of lesions, which have considerable overlapping histologic features. These neoplasms can be grouped into three categories: (a) fibrous dysplasia; (b) ossifying fibroma; (c) and osseous dysplasia. Important lesions in the differential diagnosis ...

OBJECTIVES To investigate the clinical manifestation and surgical outcome of spinal osteoblastoma. METHODS From June 2006 to July 2011, 18 patients with spinal osteoblastoma treated surgically were analyzed retrospectively. There were 11 males and 7 females with an average age of 27.5 years（range, 16-38 years). The tumors were located at C5 in 7, C6 in 6, C7 in 3, C6-T1 1 in 1 and T11 in 1. B...

A retrograde analysis of 64 spinal osteoblastomas treated by surgery during the period 1963 - 2005 has been made. Spinal osteoblastomas were presented in 36% of all skeletal localizations. There were 44 male and 20 female patients. The average age of patients at the time of surgery was 14 years. Localizations of the osteoblastomas were cervical spine in 8 cases, dorsal spine in 16 cases, lumbar...

osteomyelitis is an inflammatory infectious condition of bones, occurring either acutely or chronically. the clinical course of the disease leads to destructive or sclerosing patterns of the involved bone. this report presents a case of chronic focal sclerosing osteomyelitis in a 19-year-old male with a history of an uncontrolled convulsive condition. the lesion was first diagnosed as an osteob...
