Basaloid Squamous Cell Carcinoma of the Nasal Cavity:A Case Report

　はじめに

　鼻・副鼻腔領域には様々な悪性腫瘍が発生する。

　今回われわれは，鼻閉を主訴とした27歳女性の鼻腔類基底細胞癌（basaloid squamous cell carci-noma：BSCC）症例を経験し，内視鏡下の切除により良好な結果が得られたので，治療経過を報告するとともに文献的検討も行った。

A 27-year-old woman had a complaint of bilateral nasal obstruction. Local findings revealed a mass occupy-ing the nasopharyngeal space and endoscopic findings revealed that the mass was pedunculated and arising from the posterior region in her right inferior concha. Extirpation of the tumor was performed with a suspicion of the high-grade malignancy of the tumor, and the extir-pation of the remnant inferior concha was followed. The histopathological and immunohistochemical diagnosis was basaloid squamous cell carcinoma. There was no signs of recurrence and distant metastasis 9 months after the surgery.
