Abstract

PURPOSE
Eruptive vellus hair cysts (EVHC) are benign lesions that affect the pediatric population and are rarely seen congenitally 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 x 9.0 x 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 x 6.0 x 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.
