NAB2::STAT6 Rearranged Carcinoma of the Parotid Gland with Sebaceous Differentiation: A Case Report.
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.
Methods: Fine-needle aspiration (FNA), histopathology, immunohistochemistry, and molecular studies of this case were described.
Results: Fine-needle aspiration (FNA) revealed atypical basaloid cells, suggesting primary salivary gland carcinoma or metastasis. Histological examination showed basaloid-squamous cells with a monomorphic appearance containing foci of sebaceous differentiation, expressing pancytokeratin, p40, and androgen receptor, while CD34 staining was negative. Molecular studies identified a NAB2::STAT6 fusion, along with an AKT1 mutation.
Conclusion: This case further expands the phenotypic spectrum of NAB2::STAT6 rearranged neoplasms and emphasizes comprehensive histopathological and molecular analysis in challenging head and neck tumors. It suggests STAT6 immunohistochemistry as a potential screening tool for head and neck tumors resembling sebaceous carcinoma, myoepithelial tumors, or GLI1-altered neoplasms.
期刊介绍：
Head & Neck Pathology presents scholarly papers, reviews and symposia that cover the spectrum of human surgical pathology within the anatomic zones of the oral cavity, sinonasal tract, larynx, hypopharynx, salivary gland, ear and temporal bone, and neck.
The journal publishes rapid developments in new diagnostic criteria, intraoperative consultation, immunohistochemical studies, molecular techniques, genetic analyses, diagnostic aids, experimental pathology, cytology, radiographic imaging, and application of uniform terminology to allow practitioners to continue to maintain and expand their knowledge in the subspecialty of head and neck pathology. Coverage of practical application to daily clinical practice is supported with proceedings and symposia from international societies and academies devoted to this field.
Single-blind peer review
The journal follows a single-blind review procedure, where the reviewers are aware of the names and affiliations of the authors, but the reviewer reports provided to authors are anonymous. Single-blind peer review is the traditional model of peer review that many reviewers are comfortable with, and it facilitates a dispassionate critique of a manuscript.
