Abstract

Purpose

Eruptive vellus hair cysts (EVHC) are benign lesions that affect the pediatric population and are rarely seen con-genitally or in young adults. EVHCs are small, cystic papules that usually occur on the chest and proximal extremities. EVHCs of the eyelids have been reported infrequently. We experienced a case of solitary EVHC that developed on the eyelid in a middle-aged male. Herein, we present our case with a brief review of the literature.

Case summary

A 44-year-old male presented with a history of an asymptomatic, palpable mass in the right upper eyelid that had been slowly growing for 2 years. Physical examination revealed non-tender, firm and round mass in right upper eyelid. Computed tomography scan of the orbit showed a 7.0 × 9.0 × 9.5 mm-sized focal bulging contour in the right upper eyelid. The patient underwent sub-brow incision and excisional biopsy of the eyelid mass. Histopathological examination revealed a 7.0 × 6.0 × 4.0 mm-sized cystic structure lined by squamous epithelium containing laminated keratinous materials and multiple vellus hair shafts. There was no local recurrence during the postoperative follow-up.

Conclusions

We experienced a rare case of EVHC that developed on the eyelid. Based on our experience, EVHC should be considered when determining an eyelid mass, especially around hair follicles.
