Vellus Hair Cyst of the Orbit.

Eruptive vellus hair cysts are a developmental abnormality of vellus hair follicles that result in small cystic papules occurring most frequently on the chest and proximal extremities. Lesions of the ocular adnexa are extremely rare, and to the best of the authors knowledge, involvement of the orbit has never been reported. The authors describe a patient with an eruptive vellus hair cyst involving the orbit.
