Brow arch cyst

Brow arch cyst is a kind of dermoid cyst. Dermatoid cysts are congenital new skin-like organisms. Due to abnormal development at the embryonic stage, ectodermal leaves are partially broken and buried under the skin or conjunctival tissue. Prone to occur inside or outside the eyelid, the site of occurrence is related to the orbital bone suture, often originating from this type of bone suture. Can also occur in the arch, orbit and conjunctiva.
