Article Abstract
Background: Extraskeletal osteosarcoma, unlike skeletal osteosarcoma, is a rare malignant mesenchymal tumor with a soft tissue primary that has been reported to occur in a variety of soft tissues.
Case Description: The case is a 14-year-old, unneutered male Miniature Pinscher, weighing 6.7 kg, who had been treated medically for more than 5 years with a management strategy of puncture extirpation of a salivary gland cyst in the mandible; 1 month earlier, the fluid retention could not be removed, and after a computerized tomography scan showed no lesion in the mandible adjacent to the mass lesion, surgical resection was performed.
Conclusion: Previous reports of extraskeletal osteosarcoma from the salivary glands in dogs have been rare. However, treatment of a salivary gland cyst in the mandible by long-term puncture extirpation may be a potential predisposing factor for the development of extraskeletal osteosarcoma around the mandible.

Background: High-grade osteosarcoma is the most prevalent primary malignant bone tumor in children and adolescents. Despite advancements in chemotherapy and surgical techniques, survival rates have stagnated, particularly in patients presenting with metastases or poor chemotherapeutic response. This study aims to evaluate survival outcomes and identify prognostic factors influencing overall survival in pediatric osteosarcoma patients treated at a tertiary care center.

Osteosarcoma (OS) and extraskeletal osteosarcoma (EOS) in dogs exhibit histological similarities but differ in anatomical origin, which poses a challenge to diagnostic accuracy. We adopted a marker-first strategy to enhance molecular classification by selecting RUNX2, KPNA2, and SATB2, three validated immunohistochemical (IHC) markers, as primary targets. Bioinformatic screening identified the miR-30 family as the only miRNA group predicted to coordinately regulate RUNX2, KPNA2, and SATB2, justifying its prioritization for expression analysis.

Here, we present a rare case of a 74-year-old woman with intermittent haematuria for 6 months. Computed tomography urography showed an ill-defined heterogeneously enhancing soft tissue lesion near the neck of the bladder. The patient was advised of radical cystectomy with an ileal conduit for which the patient was unwilling.

Background: Ewing's sarcoma (ES), first described by Ewing in 1921, is a highly malignant small blue round cell tumor that arises in bone or extraskeletal soft tissues. It predominantly affects patients aged 10 to 30 years. Approximately 12% of cases involve solid organs, often presenting as rapidly growing masses in deep soft tissues.
