Overview
A double-chin appearance is also common if the cyst develops below the mylohyoid muscle.[1]
Physical Examination
- Physical examination findings in patients with dermoid cyst may include:[2][3][3][4][5][1]
- Painless swellingthat may be freely mobile or fixed to the skin and deeper structures.
- A tuft of hairs emanating from a midline nasal depression or nodule may represent a nasal dermoid cyst.
- A tarsal dermoid cyst may present as a firm, non tender nodule in the eyelid.
- Periorbital demoid cysts usually appear on the lateral aspect of the eyebrow.
- When the dermoid cyst appears on the medial aspect, the differential diagnosis of an encephalocele becomes higher.
- Dermoid cysts of the scalp or orbit may cause pressure erosion of the underlying bone which appears as a punched out defect in the skull x rays.
- A double-chin appearance is a common finding if the cyst develops below the mylohyoid muscle.
- Congenital dermoid cysts localized to the scalp, neck or trunk are usually visible at birth.
