A solitary fibrous tumor (SFT) of the parapharyngeal space presented with local symptoms (hearing loss, nasal obstruction, and paralysis of the soft palate and tongue). SFT, originally described as a mesothelial tumor of the pleura, now is recognized as a mesenchymal tumor that occurs in different locations. In the head and neck region, about 50 cases have been reported. This is the fifth published report of an SFT of the parapharyngeal space. The diagnosis was confirmed by immunohistochemical (positivity for vimentin, CD34, and CD99) and ultrastructural markers (fibroblastic characteristics).

Introduction: Benign and malignant myxoid soft tissue tumors have shared clinical, imaging, and histologic features that can make diagnosis challenging. The purpose of this study is comparison of the diagnostic performance of a radiomic based machine learning (ML) model to musculoskeletal radiologists.
Methods: Manual segmentation of 90 myxoid soft tissue tumors (45 myxomas and 45 myxofibrosarcomas) was performed on axial T1, and T2FS or STIR magnetic resonance imaging sequences.

Background: Fibrous dysplasia (FD) is the most common benign tumor of the ribs, with surgical resection being the preferred treatment modality for rib FD, leading to enhanced quality of life and favorable outcomes. The complexity of surgical intervention varies depending on the location of costal FD, presenting challenges for both open surgical and thoracoscopic approaches. In this study, we present a novel technique for three-port robotic-assisted costectomy utilizing a Gigli saw, detailing our initial findings and outcomes.
