Epidermal inclusion cyst (EIC) is one of the common conditions usually associated with trauma. This cyst commonly presents on the scalp, face, neck, trunk, and extremities. Epidermal inclusion cyst is believed to originate through implantation of epidermal element by either surgical or accidental trauma into deeper mesenchymal tissue and its subsequent cystic transformation. The EICs are indolent in nature, slow to progress, and remain asymptomatic unless secondarily infected. The authors report a case of EIC that occurred in a 35-year-old female after surgery of squamous cell carcinoma.
