Sixty seven-year-old ex-tobacco user patient presented with a deep excavating ulcer in the left preauricular area with ear discharge, pain and facial nerve palsy [Figure 1a]. Computed tomography scan showed 4.3 cm × 3.3 cm hypodense soft tissue mass extending from preauricular soft tissue into the left external ear and middle ear causing destruction of ear ossicles (cT4N0M0).
