Basaloid squamous cell carcinoma (BSCC), an uncommon tumor with predilection for the upper aerodigestive tract, is a dis-tinct variant of squamous cell carcinoma, because of its unique histological features and ominous clinical behavior. Basaloid 1986 by Wain et al. have confirmed that the head and neck region is the most frequently involved region, with majority of the cases arising in the supraglottic larynx, hypopharynx, tonsil and base of tongue. Other head and neck sites include the pa-late, buccal cavity, flor of mouth, nasopharynx, trachea, and sinonasal tract. BSC is not limited to the head and neck region but has also been described in the esophagus, lung, thymus, anus and cervix among other sites. We experienced and treated a report here the rare case of BSCC invading the temporal bone with literature. (Korean J Otolaryngol 2002;45:719-21)
