A one-month-old female baby had been noted to have multiple vesicles and pustules over the head, face, trunk and four extremities since she was one-week-old. Under the impression of disseminated herpes virus infection, intravenous acyclovir was given after admission. Serum herpes simplex virus and varicella zoster virus enzyme-linked immunosorbent assay test and virus culture were all fruitless...

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...

Giant cell tumour (GCT) is a benign, locally aggressive tumour of the bone that accounts for 5% of primary bone tumours and 21% of benign bone tumours. This tumour more commonly presents as a single (solitary) lesion; however, it may appear with multiple (multicentric) lesions in less than 1% of the cases. According to the literature, 1-9% of solitary GCTs metastasizes to the lung, more commonl...

Fibrous dysplasia (FD) belongs to a group of lesions known as fibro osseous lesions (FOL) whereby normal bone is replaced with fibrous tissue containing abnormal bone or cementum. FOL are the most frequent and the most difficult lesions to diagnose, as they share overlapping spectrum of clinicopathological, radiological, and immunological characteristics. In this retrospective study of 134 maxi...

Cherubism is a benign fibro-osseous disease of childhood limited specifically to the maxilla and mandible. The progressive replacement of the jaw bones with expansile multilocular cystic lesions causes eventual prominence of the lower face, and hence the classic "cherubic" phenotype reflecting variable extents of jaw hypertrophy. Histologically, this condition has been characterized as replacem...

No. 123, Ta Pei Road, Kaohsiung 833, Taiwan, R.O.C. Aneurysmal bone cyst (ABC) infrequently involves the calvarium and is even more unusual at the skull base. The sporadic reported cases of ABC occur primarily in the pediat...

In spite of very high sensitivity, bone scan is quite nonspecific in evaluation of bony lesions. In interpretation of bone scan special attention to patient’s clinical presentation and correlation with other lab and imaging modalities should be paid. In this report a patient with Erdheim Chester disease a rare and unusual form of lipidosis is presented and the pattern of 99mTc-MDP bone sc...

An unmet need remains for a bone graft substitute material that is biocompatible, biodegradable and capable of promoting osteogenesis safely in vivo. The aim of this study was to investigate the use of a novel collagen-hydroxyapatite (CHA) bone graft substitute in the clinical treatment of a mandibular bone cyst in a young horse and to assess its potential to enhance repair of the affected bone...
