Dermoid Cysts Symptoms and Diagnosis

Symptoms of Dermoid Cysts

In most cases, the only dermoid cyst symptom is a small, painless lump under the skin. The lump may be the same color as your child’s skin or it may be pale yellow. Dermoid cysts usually show up:

  • Near the eyebrow
  • On the scalp
  • On the chest
  • Over the collarbone

If a dermoid cyst gets infected, it may hurt, become swollen and red or burst. The infection may cause a fever.

Dermoid Cysts Diagnosis

Our doctors diagnose a dermoid cyst with a physical exam. During the exam, the doctor will feel the lump and ask questions about it, such as when you first noticed the lump and how fast it has grown. Sometimes a child needs further tests to see how deep their cyst goes into the body and if it is connected to other tissues. These tests include:

  • CT (computed tomography) scan
  • MRI (magnetic resonance imaging)

These tests will help us decide whether your child needs dermoid cyst treatment.
