A basaloid squamous cell carcinoma (BSCC) is a poorly differentiated SCC composed of basaloid cells and squa-mous cell carcinoma, characterised by an aggressive clinical course. It was first described by Wain et al. in 1986 . It has a predilection for the upper aerodigestive tract, but also occurs in other locations such as the uterine cervix , oesophagus , lung , and anus .
In the upper aerodigestive tract, BSCC shows a predilection for the hypopharynx (pyriform sinus), base of the tongue, and supraglottic larynx [195, 293]; it has also been described in the oropharynx [195, 293], oral cavity [69, 72, 159] and trachea [277, 312]. The suggested precursor of the BSCC is a totipotent primitive cell located in the basal cell layer of the surface epithelium, or within the seromucinous glands [293, 372].
