Causes of hair cysts

Hair cysts originate in the isthmus of growing hair or hair follicles surrounding degenerating and stationary hair, and present an autosomal dominant genetic disease.

Clinical manifestations of hair cysts

Hair cysts are rare in the clinic, and more than 90% occur in the scalp. The distribution is different from epidermal cysts and cannot be distinguished from epidermal cysts.

Hair cyst diagnosis

Hair cysts require a biopsy to make a clear diagnosis.

Differential diagnosis of hair cysts

The disease should be distinguished histologically from proliferative outer hairy root sheath tumors, which are solid tumor-like hyperplasia. Tumor cells may have mild atypia, and squamous vortices and individual keratosis are seen.

Hair Cyst Treatment

Surgery.
