    Thyroid-like low-grade nasopharyngeal papillary adenocarcinoma (TL-LGNPPA) is a rare tumor with histological features similar to papillary thyroid carcinoma.

  • 2

    Common clinical presentations of TL-LGNPPA include nasal obstruction, nasal bleeding, and rhinorrhea, but some cases are asymptomatic.

  • 3

    Histological examination reveals typical papillary and ductal structures, with a fibrous vascular axis and mild to moderate nuclear atypia.

  • 4

    Immunohistochemical analysis shows that TL-LGNPPA expresses TTF-1 and CK, while TG is mostly negative, with a Ki-67 index generally ≤10%.

  • 5

    Accurate diagnosis of TL-LGNPPA requires comprehensive histological assessment, immunohistochemical analysis, and imaging studies.
