Case Discussion

A trichilemmal cyst, also known as a wen, is a common cyst that forms from a hair follicle. They are most often found on the scalp. The cysts are smooth, mobile and filled with keratin, a protein component found in hair, nails, and skin. They may or may not be tender.

Trichilemmal cysts may run in families. In this case the keratin has calcified.
