Basaloid squamous cell carcinoma (BSCC) is a rare variant of squamous cell carcinoma and is known for its aggressive behaviour. It occurs predominantly in the upper aerodigestive tract and presentation in the nasal cavity and paranasal sinus is extremely rare. We present here a case of BSCC in a 36 year female arising in the paranasal sinus with orbital and intracranial extension. Clinical and pathological findings including immunohistochemistry is presented along with brief discussion of literature.
