On physical examination, a papillomatous tumor was observed at the posterior wall of the inlet of the left external auditory canal (Figure 1(a)). One week after resection of the polyp, the postoperative wound at the external auditory canal had almost completely epithelialized (Figure 1(b)), and the chief complaint, aural fullness, had resolved.
Fibroepithelial polyp covered by epidermis with hyperkeratosis leading to irregular epidermal projections and interstitial proliferation (hematoxylin-eosin staining: (a) x40; (b) x400).
