Epidermoid and dermoid cysts are benign, usually slow-growing lesions classified as ectodermal inclusion cysts. These cysts form when epithelial remnants become trapped during the closure of the first and second branchial arch; however, a few cases are related to trauma or are iatrogenic. Diagnosis is made based on the cyst development history and imaging such as ultrasound. Surgical excision is the treatment of choice to avoid complications. We report a case report of a dermoid cyst in the pre-sternal region in a 17-year-old male patient.
