Clinicopathologic characteristics of low-grade thyroid-like nasopharyngeal papillary adenocarcinoma: a case report.
Low-grade thyroid-like nasopharyngeal papillary adenocarcinoma is a rare malignant tumor characterized by morphologic analogy to papillary thyroid carcinoma and aberrant thyroid transcription factor-1 (TTF-1) expression. To date, a limited number of cases have been reported in the literature. We report a case of a 20-year-old Chinese male patient with complaints of headaches and nosebleeds for 5 months. The histopathologic examination showed thyroid-like low-grade nasopharyngeal papillary adenocarcinoma that was confirmed by immunohistochemical staining. The patient was treated with macroscopic complete resection without adjuvant therapy. The epidemiologic characteristics and clinical and pathologic features of the disease are summarized. In addition, we summarize the treatments used previously. In general, TL-LGNPPA is a very rare low-grade adenocarcinoma with aberrant expression of TTF-1, and its diagnosis depends on morphology and immunophenotype. The prognosis is good.
期刊介绍：
The International Journal of Clinical and Experimental Pathology (IJCEP, ISSN 1936-2625) is a peer reviewed, open access online journal. It was founded in 2008 by an international group of academic pathologists and scientists who are devoted to the scientific exploration of human disease and the rapid dissemination of original data. Unlike most other open access online journals, IJCEP will keep all the traditional features of paper print that we are all familiar with, such as continuous volume and issue numbers, as well as continuous page numbers to keep our warm feelings towards an academic journal.
