[Basosquamous carcinoma of the floor of the mouth].
Basaloid-squamous cell carcinoma is a rare tumor characterized by Wain et al in 1986 as a separate pathological entity. In head and neck more than 100 cases have been reported, with a strong predilection for hypopharynx, base of tongue, and supraglotic larynx. This entity also has been described in nasal cavity, oesophagus, tonsils and oral cavity. Only 14 cases has been reported arising in the floor of the mouth, and none in our literature. We present a new case in floor of the mouth and clinicopathological features are emphasized. We have undertaken moreover a bibliographic review of this uncommon and aggressive neoplasm.
