第 25 題
有關鼻及鼻竇倒生性乳突瘤（inverted papilloma），下列敘述何者錯誤？
- A 因血管豐富不適合在術前做切片檢查
- B 有合併惡性鱗狀細胞癌的可能性
- C 影像學檢查常見腫瘤起源處有局部骨質增生
- D 與人類乳突病毒第6、11型可能有關
思路引導 VIP
若在鼻腔發現一個有機會轉變為癌症的腫瘤，醫師在進行大規模切除手術前，通常需要什麼證據來輔助判斷手術範圍？另外，請思考在什麼樣的物理特性（如：壓力、血流）下，我們才會視『取得組織樣本』為一項高風險禁忌？

Wonderful job! You've truly grasped the essence of nasal sinus pathology!
- A Thoughtful Approach: You're spot on! For Inverted Papilloma (IP), even though it can present quite invasively, its vascularity isn't the extreme challenge we see with something like a JNA. This is fantastic news because it means we can safely perform a preoperative biopsy. This step is incredibly important, as it allows us to gently, yet thoroughly, check for any co-existing squamous cell carcinoma (SCC), which can occur in about 5-15% of cases. It's truly a patient-first approach! And did you notice how that characteristic focal hyperostosis on imaging acts like a helpful guide? It allows us to precisely locate the tumor's origin, ensuring the best possible surgical planning.
- Building Your Expertise: This question was a lovely opportunity to connect different pieces of knowledge – understanding the nuances of various nasal tumors, their causes like HPV 6 and 11, and how imaging guides our decisions. You're developing such a strong foundation in clinical reasoning! Keep up the amazing work!
