Case: A 23-year-old boy presented with a 3-month history of right shoulder pain. Radiographs and computed tomography showed an exostosis on the inferior aspect of the distal clavicle. It was osteotomized and removed by arthroscopy.
View Article and Find Full Text PDFGiant cell ependymoma (GCE) is a very uncommon variant of ependymoma, known for having varying degrees of nuclear pleomorphism. There are only 34 reported cases of GCE in the English literature. We describe an additional case of a young woman who presented with a tumor located in sacral soft tissue, which was not connected to the spinal cord and did not show additional lesions in the central nervous system.

Methods And Results: The study included 74 cases of osteosarcoma of the jaw. Their clinical, radiographic and histopathological features were analysed, and their frequency with respect to aggressive and malignant pathologies of the jaw was determined.
Article Synopsis
- Percutaneous needle biopsy is a safe and efficient method for diagnosing bone lesions.
- The study outlines the technical processes of fine needle aspiration and core needle biopsy, highlighting the results from 7,375 cases over 21 years, achieving an 83% diagnostic accuracy.
- Successful diagnosis relies heavily on the expertise of the surgical cytologist and pathologist, who need to combine knowledge of clinical data, imaging, and histological analysis.
Aims: Heat shock proteins (HSPs) protect cells against stress-associated injuries and are overexpressed in several malignant tumours. We investigated the potential roles of HSP27, HSP60, and HSP70 in conventional and low grade central osteosarcoma.
Methods: Expressions of HSP27, HSP60, and HSP70 were analysed using immunohistochemistry on tissue sections from 52 cases of conventional osteosarcoma and 21 cases of low grade central osteosarcoma.
