A trichilemmal cyst or pilar cyst is a common cyst that forms from a hair follicle , most often on the scalp , and is smooth, mobile, and filled with keratin , a protein component found in hair , nails , skin , and horns. Trichilemmal cysts are clinically and histologically distinct from trichilemmal horns, hard tissue that is much rarer and not limited to the scalp. Trichilemmal cysts may be classified as sebaceous cysts , [6] although technically speaking are not sebaceous. Medical professionals have suggested that the term "sebaceous cyst" be avoided since it can be misleading. Trichilemmal cysts are derived from the outer root sheath of the hair follicle. Their origin is currently unknown, but they may be produced by budding from the external root sheath as a genetically determined structural aberration. Histologically , they are lined by stratified squamous epithelium that lacks a granular cell layer and are filled with compact "wet" keratin. Areas consistent with proliferation can be found in some cysts. In rare cases, this leads to formation of a tumor, known as a proliferating trichilemmal cyst. The tumor is clinically benign, although it may display nuclear atypia , dyskeratotic cells, and mitotic figures. These features can be misleading, and a diagnosis of squamous cell carcinoma may be mistakenly rendered. Minimal excision is appropriate to treat for some trichilemmal cysts, while others require formal surgical excision.
