Chondroblastoma has a predilection for the epiphyses or apophyses of long tubular bones. Management of lesions in the proximal tibia is challenging because it is difficult to gain access to intraepiphyseal lesions for completion of curettage. From October 2007 to December 2011, 9 patients with de novo chondroblastoma of the proximal tibia underwent surgery at the authors' institution. All patie...

OBJECTIVES Chondroblastoma is a rare tumor accounting for 1% of primary bone tumors. Chondroblastoma involving the skull base is exceedingly rare with approximately 60 cases reported. We reviewed our experience with chondroblastoma of the skull base with an emphasis on current lateral skull base approaches and long-term tumor control. STUDY DESIGN AND SETTING A retrospective case review at a ...

Surgical management of tumors located in the spine and the pelvis involves greater difficulty. Moreover, these tumors are usually very large and vascularized. Preoperative embolization of the internal iliac artery is a relatively safe procedure that may reduce the risk of bleeding and local recurrence in the case of benign tumors. Chondroblastoma is a tumor that is rarely located in the pelvis;...

Benign chondroblastoma of mandibular bone is an extremely rare tumor. Although 9 cases have been reported in the mandibular condyle in the English literature, to the best of our knowledge this is the first case originated from anterior mandible in a 31-year-old male.

A benign chondroblastoma of bone is reported. It was unusual because it occurred in an old lady, in a toe, and it was not painful and radiologically resembled a chondroma. The coarsely lobulated tumour showed a varied microscopic appearance, but it consisted chiefly of closely packed sheets of small, round polygonal or fusiform cells. There was some calcification present. The literature is revi...

o bjectives: pneumatized articular eminence or tubercle (pat) is an air cell cavity in the zygomatic process of the temporal bone. pneumatization of articular eminence may be seen incidentally on panoramic radiographs (pr) as a unilocular or multilocular, radiolucent defect. the aim of this study was to assess the prevalence and the pattern of pat on pr in an iranian population. materials and m...

PURPOSE To review all patients with chondroblastoma treated in our hospital between 1993 and 2004. METHODS Six men and 4 women aged 13 to 33 (mean, 21) years with histologically proven chondroblastomas were retrospectively reviewed through our tumour registry, patient records, radiographic and histopathologic reports. All patients underwent intralesional curettage and bone grafting with or wi...

introduction: osteomas are asymptomatic and rare slow growing bony tumors in temporal bone, and should be taken into account in differential diagnosis of the osteolytic solitary skull lesions. sometimes is associated with pain and functional loss. only a few cases have been reported.   case report: we describe a case of an osteoid osteoma of the temporal bone (mastoid) in a 31-year-old woman pr...

in this research, anatomical descriptions of the structure of the temporal bone and auditory ossicles have been performed based on dissection of ten guinea pigs. the results showed that, in guinea pig temporal bone was similar to other animals and had three parts; squamous, tympanic and petrous .the tympanic part was much better developed and consisted of oval shaped tympanic bulla with many re...
