Cysts – Dermoid Cysts

December 15th, 2010

Dermoid Cysts, also called teratomas, are congenital cysts that are found in the subcutaneous tissue and are relatively rare but I do encounter them in both my The Woodlands and Conroe dermatology offices.  Dermoid Cysts arise from anomalies in embryonic development so they arise along embryonic closure lines.  Dermoid Cysts consist mainly of fatty tissue but may contain hair, teeth, and nails.  They usually occur on the lateral portion of the eyebrow, at the nasal root, the midline of the forehead, the floor of the mouth, chest, back, abdomen and can be found perianally.   Dermoid Cysts are also found in the nervous system and ovaries.  Dermoid Cysts occur equally amongst the sexes.  Dermoid Cysts are benign but there are rare reports of malignant transformation.  Treatment involves excising the entire cyst, however imaging is usually performed in children to ensure there is not intracranial or intraspinal connections.
