Although most peripheral nerve sheath tumours are benign, some are malignant. The management of malignant tumours usually involves wide excision and is facilitated by knowledge of the diagnosis prior to operation. Imaging modalities, including MRI, give anatomical information but do not distinguish between benign and malignant nerve tumours. We therefore introduced the use of ultrasound guided

The pre-operative differentiation between enchondroma,
low-grade chondrosarcoma and high-grade chondrosarcoma remains a
diagnostic challenge. We reviewed the accuracy and safety of the
radiological grading of cartilaginous tumours through the assessment
of, first, pre-operative radiological and post-operative histological agreement,
and second the rate of recurrence in lesions confirmed as high-grade
on histology. We performed a retrospective review of major long
bone cartilaginous tumours managed by curettage as low grade between
2001 and 2012. A total of 53 patients with a mean age of 47.6 years
(8 to 71) were included. There were 23 men and 30 women. The tumours
involved the femur (n = 20), humerus (n = 18), tibia (n = 9), fibula
(n = 3), radius (n = 2) and ulna (n = 1). Pre-operative diagnoses
resulted from multidisciplinary consensus following radiological
review alone for 35 tumours, or with the addition of pre-operative
image guided

Introduction: Pathological fractures commonly undergo biopsy to establish tissue diagnosis and plan definitive surgical management. Methods: 129 patients undergoing image-guided
Introduction. Tissue diagnosis is essential to direct the definitive management of a suspected soft tissue or bone sarcoma tissue. Knowledge of both the diagnostic yield and accuracy of core
Core needle: From the other 335, 116 were benign tumours or tumour-like conditions, 86 primary malignant, 53 lesions oh Hematopoietic, lymphoid and biopsy is simple, practical and easily permits diagnosis of bone and soft tissue tumours and tumour-like conditions even when immunohistochemical studies are needed. We present the results of 412 core

Introduction.
Aims. Low-grade central osteosarcoma (LGCOS), a rare type of osteosarcoma, often has misleading radiological and pathological features that overlap with those of other bone tumours, thereby complicating diagnosis and treatment. We aimed to analyze the clinical, radiological, and pathological features of patients with LGCOS, with a focus on diagnosis, treatment, and outcomes. Methods. We retrospectively analyzed the medical records of 49 patients with LGCOS (Broder’s grade 1 to 2) treated between January 1985 and December 2017 in a single institute. We examined the presence of malignant features on imaging (periosteal reaction, cortical destruction, soft-tissue invasion), the diagnostic accuracy of biopsy, surgical treatment, and oncological outcome. Results. Based on imaging, 35 of 49 patients (71.4%) exhibited malignant features. Overall, 40 of 49 patients (81.6%) had undergone a biopsy before en-bloc resection: 27 of 40 patients (67.5%) were diagnosed on the first biopsy, which was more accurate when carried out by open rather than
The December 2023 Oncology Roundup. 360. looks at: A single osteotomy technique for frozen autograft; Complications, function, and survival of tumour-devitalized autografts used in patients with limb-sparing surgery; Is liquid nitrogen recycled bone and vascular fibula the biological reconstruction of choice?; Solitary pulmonary metastases at first recurrence of osteosarcoma; Is a radiological score able to predict resection-grade chondrosarcoma in primary intraosseous lesions of the long bones?; Open versus core
Cartilage lesions vary in the spectrum from benign enchondromas to highly malignant dedifferentiated chondrosarcomas. From the treatment perspective, enchondromas are observed, Grade 1 chondrosarcomas are curetted like aggressive benign tumors, and rest are resected like other sarcomas. Although biopsy for tissue diagnosis is the gold standard for diagnosis and grade determination in chondrosarcoma, tumor heterogeneity limits the grading in patients following a biopsy. In the absence of definite pre-treatment grading, a surgeon is therefore often in a dilemma when deciding the best treatment option. Radiology has identified aggressive features and aggressiveness scores have been used to try and grade these tumors based on the imaging characteristics but there have been very few published reports with a uniform group and large number of cases to derive a consistent scoring and correlation. The authors asked these study questions :(1) Does Radiology Aggressiveness and its Score correlate with the grade of chondrosarcoma? (2) Can a cut off Radiology Agressiveness Score value be used to guide the clinician and add value to
Introduction: Chondrosarcoma is the second most common primary malignant bone tumour. Distinguishing between grades is not necessarily straightforward and may alter the management of the disease. We evaluated the correlation between the pre-operative
