title: [Thyroid-like low-grade nasopharyngeal papillary adenocarcinoma: one case report].
abstract: Thyroid-like papillary adenocarcinoma is an extremely rare neoplasm in the nasopharynx. We present a case with a pedunculated tumor in the nasopharyngeal vault. Complete tumor resection via nasal endoscopy was performed subsequently. Postoperative histopathological examinations and immunohistochemical studies confirmed the diagnosis of thyroid-like papillary adenocarcinoma. This rare neoplasm demonstrated a distinct etiology and nature from typical nasopharyngeal carcinomas and should be managed mainly by surgical resection.
