(a) A 0.5 cm × 0.5 cm anterior-based, pedunculated, bony mass was observed in the right external auditory canal; (b) temporal bone computed tomography revealed a 0.5 cm × 0.5 cm anterior-based, pedunculated, bony mass originating from the tympanosquamous suture line, and (c) histopathologic image showed stratified squamous epithelium overlying the mass of trabeculae of mature lamellar bone (arrow) with a variable amount of fibrofatty marrow tissue (arrowhead) (hematoxylin-eosin, ×40).
