Description
Thyroid-like low grade nasopharyngeal papillary adenocarcinoma(TL-LGNPPA)は上咽頭に発生する稀な低悪性度腫瘍である。甲状腺乳頭癌の組織像に類似し,TTF-1が陽性,Thyroglobulinは陰性を示す。われわれは,鼻中隔後端に発生したTL-LGNPPA例を経験した。症例は30歳女性で,鼻中隔後端の腫瘤を偶然発見された。術前診断は外反性乳頭腫であり,摘出術を行った。術後の病理検査でTL-LGNPPAと診断した。断端は陰性であり追加治療は行わなかった。術後1年以上経過したが再発や転移は認めていない。
Description Alternative
Thyroid-like low-grade nasopharyngeal papillary adenocarcinoma (TL-LGNPPA) is a rare low-grade tumor that predominantly occurs in the nasopharynx. The tumor shows papillary thyroid carcinoma-like histopathology, positive for thyroid transcription factor-1 (TTF-1), but negative for thyroglobulin. We report a case of TL-LGNPPA at the posterior end of the nasal septum. A 30-year-old woman was found by chance to have a tumor at the posterior end of the nasal septum. We preoperatively diagnosed the tumor as an exophytic papilloma and endoscopically resected the tumor. The tumor was diagnosed by postoperative histopathology as TL-LGNPPA. More than one year after surgery, there is no evidence of recurrence or metastasis.
