An unusual location of newborn huge dermoid cyst: a case report and literature review

Abstract Background Dermoid cysts are benign germ cell tumors with ectodermal and mesodermal components. It is a slow-growing lesion that commonly arises in the midline of the head and neck. The last location represented 7%, and the periorbital region was the most frequently arising area. True lateral neck dermoid cysts are rare. We present an unusual location of a dermoid cyst in a newborn. Case presentation We report an unusual location of a 10-day newborn giant dermoid cyst with multiple implantation sites, namely the shoulder, scapula, cervical, temporal, and occipital scalp. Successful surgical resection was achieved, and the patient was discharged after the removal of the stitches. Conclusion Dermoid cysts are unusual neoplasms with rare diagnoses at birth, but often in childhood. Concomitant implantation locations on the shoulder, neck, temporal, and occipital scalps are rare.
