Quick Summary

A dermoid cyst is a type of cystic tumor, often found on the ovary. It is characterized by containing skin and skin derivatives, such as hair or teeth. The term "dermoid" itself means resembling skin.12

Cysts, in general, are sacs within body tissues that have a distinct membrane and typically contain liquid material. While most cysts are benign, some can be malignant or precancerous. Benign cysts may need to be removed if they interfere with surrounding organs. Cysts can form from epithelial tissue and may contain various substances, including natural secretions, abnormal breakdown products, or even infectious agents like bacteria or parasites. Organs like the kidney, liver, and breast are particularly prone to cyst formation.3

Epidemiology and pathology
Dermoid cysts, which tend to affect the ovaries, typically contain hair, skin, and other ectoderm-derived cell types. Sacrococcygeal teratomas, which affect infants, develop under the coccyx (tailbone) in a region known as Hensen’s node, which houses germ cells that differentiate to form the ectoderm, endoderm,…
