Prevention & Risk Treatment
What causes a dermoid cyst?
A dermoid cyst is a congenital defect (present from birth) that occurs during embryonic development when the skin layers do not properly grow together. A dermoid cyst is lined with epithelium, which contains tissues and cells normally present in skin layers, including hair follicles, sebaceous (skin oil), and sweat glands. These glands and tissues secrete their normal substances which collect inside the cyst, causing it to grow and enlarge.
What are the symptoms of a dermoid cyst?
The following are the most common symptoms of a dermoid cyst. However, each child may experience symptoms differently. Symptoms may include a small, often painless, lump in the mid-line of the neck (in which the skin over the lump can easily be moved). The lump may be skin-colored, or may have a slight yellow tinge.
The symptoms of a dermoid cyst may resemble other neck masses or medical problems. Always consult your child's physician for a diagnosis.
