ABSTRACT

Basaloid squamous carcinoma(BSC) is a rare tumor with distinct morphologic and biologic features that separates it from the more common squamous cell carcinomas of the head and neck region. Basaloid squamous carcinoma strongly predilects the hypopharynx, base of tongue, supraglottic larynx, or tonsil and frequently is accompanied by cervical lymph node metastasis. It is characterized histologically by small, crowded basaloid cells with many small cystic spaces，focal squamous differentiation in basaloid clusters, and prominent intercellular hyalinosis. Treatment of BSC is smilar to that of conventional squamous cell carcinoma. Nevertheless, BSC should be distinguished from other squamous cell carcinomas, because of its typically high stage at presentation and distinctive microscopic appearance with potential for diagnostic confusion.

Recently authors experienced one case of basaloid squamous cell carcinoma of supraglottis. We report our case with brief review of literature.
