Basaloid squamous cell carcinoma of the head and neck with a spindle cell component. An unusual histologic variant.

We describe two cases of basaloid squamous cell carcinoma of the head and neck with a spindle cell component. One tumor arose from the tonsil and the other in the larynx. Of the 30 cases of basaloid squamous cell carcinoma seen at this medical center, only 2 (6.6%) have demonstrated this histologic feature. To our knowledge, scant information exists with regards to a prominent spindle cell component occurring in basaloid squamous cell carcinoma, and none has been officially documented.
