The skeletal neoplasms of small dogs are characterized poorly. In this retrospective study, the bone tumors of 37 small dogs (with body weights less than 15 kg), 74 large dogs (with body weights greater than 25 kg), and 134 small dogs previously reported in the literature were compared. Metastases accounted for about 25% of the bone tumors in small dogs, but less than 5% of the bone tumors in large dogs. In small dogs, osteosarcomas represented less than 50% of all skeletal neoplasms, frequently affected the axial skeleton, and had no apparent predilection for the distal radius. In this series and in the literature, fewer than 10 small dogs with appendicular osteosarcoma were treated with curative intent. Clinicians should use caution when extrapolating information on the biological behavior of osteosarcoma from large- and giant-breed dogs to small dogs.

Introduction: The purpose of this paper is to study the type, the clinical presentation, and the best diagnostic methods for pleural solitary fibrous tumors (PSFTs), as well as to evaluate which is the most appropriate treatment, especially as PSFTs represent a rare occurrence in the thoracic pathology. Material and Method: A retrospective study was conducted on a group of 45 patients submitted to surgery between January 2015 and December 2019. In most cases, the diagnosis was established through imaging studies—thoracic computed tomography (CT) scan with or without contrast—but also using magnetic resonance imaging (MRI) or positron emission tomography (PET) scans when data from CT scans were scarce. All patients were submitted to surgery with curative intent. Results: Most patients included in this study were asymptomatic, with this pathology being more common in patients over 60 years of age, and more common in women. The occurrence of malignant PSFT in our study was 17.77% (8 cases). All cases were submitted to surgery with curative intent, with a single case developing further recurrence. In order to achieve complete resection en bloc resection of the tumor with the chest wall, resection was performed in two cases, while lower lobectomy, pneumectomy, and hemidiaphragm resection, respectively, were needed in each case. Postoperative mortality was null. Conclusion: Thoracic CT scan remains the most important imagistic investigation in diagnosing. MRI is superior to thoracic CT, especially in cases that involved the larger blood vessels within the thorax, spinal column, or diaphragm. Complete surgical resection is the gold standard in treatment of PSFT, and the prognosis in benign cases is very good.
