Osteochondromas found within the soft tissue without osseous or intra-articular involvement are better described as extraskeletal osteochondromas. They are slow-growing, benign, osseous tumors, and are often misdiagnosed as conventional osteochondromas. Though extraskeletal osteochondromas are rare, they typically affect the digits of the hands or feet. We present a patient with a giant symptom...

We report a case of progressive osseous heteroplasia in a female infant who had progressive ossification of the skin and deep connective tissues. Isolated dermal ossification is present in her father and younger sister suggesting an autosomal dominant mode of inheritance with variable expressivity or possible somatic mosaicism. This report of a family with progressive osseous heteroplasia contr...

This paper presents a case of osseous metaplasia of the endometrium, a rarely encountered disease. Metaplasia is described as a change of one epithelium into another epithelium due to some triggering factor. In this case, endometrium is converted into osseous spicules. It might be followed by an abortion presenting with Infertility or chronic endometritis or metabolic disorder like hypervitamin...

Extracranial metastases from glioblastoma multiforme (GBM) are rare. We report a case of osseous metastases from GBM diagnosed by F-NaF PET/CT. A 30-year-old man with a history of GBM presented with bone pain and underwent F-NaF PET/CT for further evaluation. On PET/CT, intense uptake in 2 bone lesions was noted. Histopathologic evaluation revealed osseous metastases from GBM. Although rare, bo...

For our study were available fragments of bony tissue from 24 patients (15 females and 9 males) aged between 55–82 which needed hip arthroplasty after they had undergone femural neck fractures. Biologic pieces have been fixed, then decalcified and processed by wax embedding. We noted that the spongious osseous tissue appeared as rarefied after the remoulding processes; osseous traveas grew unpl...

BACKGROUND Malignant melanoma occurs infrequently in Taiwan. Once it has progressed into osseous metastases, the prognosis is poor. There are no reported clinical experiences of surgical management in this area. METHODS To improve our understanding of the rare clinical experiences, we retrospectively investigated clinical characteristics, radiological findings, treatment modalities, survival ...

STATEMENT OF THE PROBLEM Jaw bone lesions are common pathologic conditions. The role of ultrasonography in evaluation of the extra-osseous lesions is confirmed, however, this imaging modality is not the diagnostic routine for the intra-osseous jaw lesions. PURPOSE The purpose of this study was to evaluate the efficiency of ultrasonography in diagnosis of intra-osseous jaw lesions concerning t...

Chondrogenically primed bone marrow-derived mesenchymal stem cells (MSCs) have been shown to become hypertrophic and undergo endochondral ossification when implanted in vivo. Modulating this endochondral phenotype may be an attractive approach to engineering the osseous phase of an osteochondral implant. The objective of this study was to engineer an osteochondral tissue by promoting endochondr...
