摘要
錯構瘤（hamartoma）為一先天性且非侵入性的良性腫瘤，特徵為周邊組織以不正常的比例增生，根據過去的文獻，大多數的錯構瘤長在腎臟、肺臟和小腸，鼻腔、甚至於鼻咽腔的案例非常罕見，因其外觀和惡性腫瘤不易區別，診斷上主要以病理檢查為依據。本例為51歲婦人，除頭痛之外無鼻腔症狀，例行性理學檢查發現右側鼻咽上緣處有一顆腫塊，其外表顏色潤紅且平滑，經由鼻腔內視鏡搭配切片檢查，結果為一診斷不明之良性腫瘤。而後病人透過內視鏡的方式切除鼻咽的腫瘤。顯微鏡下此息肉狀腫瘤外層包覆著呼吸表皮細胞，其核心包含有小葉排列的脂肪細胞，以及平滑肌纖維、血管組織、神經束和漿液黏液性腺體穿插在其中，病理診斷為錯構瘤，此婦人經過18個月定期的追蹤檢查，並未發現有復發的情形。

Hamartoma is a benign tumor but very rare in the sinonasal tract and nasopharynx. We report a case with nasopharyngeal hamartoma which was incidentally discovered in our outpatient clinic. A 51-year-old female complained of headache without any nasal symptom. The physical examinations demonstrated a pedunculated nasopharyngeal mass extending from right nasopharyngeal vault. The pathological examination of endoscopic biopsy revealed a benign tumor without any further details. The tumor was thoroughly resected by en bloc fashion under endoscopic guidance. The final histopathological examination indicated that it was a hamartoma. No sign of recurrence was noted after the 18-month regular follow-up.
