Beyond enchondromas, the most common bone tumors of the hand, there are numerous less common benign bone tumors and mimickers with which orthopaedic and hand surgeons should be familiar. These include other benign cartilage tumors, cystic lesions, osteogenic tumors, giant cell tumor, and fibrous dysplasia. Particularly unique lesions include bizarre parosteal osteochondromatous proliferation (Nora lesion), florid reactive periostitis, turret exostosis (acquired osteochondroma), giant cell reparative granuloma (solid aneurysmal bone cyst), and epidermoid cyst.

Purpose: The NAB2::STAT6 fusion is predominantly associated with solitary fibrous tumors (SFTs) and is utilized in diagnosing SFTs through nuclear STAT6 protein overexpression. Recent studies expanded the phenotypic spectrum of NAB2::STAT6 rearranged neoplasms, including adamantinoma-like and teratocarcinosarcoma-like phenotypes. We report a case of a NAB2::STAT6 rearranged epithelial tumor exhibiting sebaceous differentiation in the parotid gland.

Objectives: Head and neck malignancies (HNMs) encompass a variety of cancers that affect the oral and para-oral tissues, the most common of which are squamous cell carcinomas. Radiotherapy is commonly used to treat these cancers, often involving radiation exposure to the salivary glands. This study aims to investigate the early impacts of radiotherapy on the internal microstructure of the salivary gland cells and identify which gland exhibits the highest level of radiosensitivity.
