Background: Epidermoid cysts are thought to arise as a result of implantation of epidermal cells into the deeper dermal elements. These cysts have previously been described postsurgery but not after accidental nasal trauma. Methods: We outline a case of a nasal epidermoid occurring post-blunt nasal trauma and its subsequent excision. Results: The lesion was excised successfully endoscopically without recourse to an open technique. Conclusion: We describe, for the first time, the successful intranasal removal of a post-traumatic epidermoid cyst via an endoscopic approach.
