Abstract

An 82-year-old woman presented with a 6-month history of an enlarging brow mass that developed after trauma. Clinical and MRI appearance of the lesion appeared consistent with epidermal inclusion cyst. However, excisional biopsy demonstrated invasive squamous cell carcinoma, which recurred 6 weeks later and required repeat surgical excision. To our knowledge, this represents the first case of squamous cell carcinoma arising from a posttraumatic epidermal inclusion cyst.
