Trichilemmal cyst of eyelid: A case report and review of literature

Abstract

<br>Trichilemmal cyst is a rare benign tumor of the skin, with distinct keratinisation and a predilection for the scalp. In the eyelid, these benign hair follicle lesions clinically mimic chalazion and recurrences occur with incomplete removal of cyst wall. To the best of authors' knowledge, only 7 cases of eyelid trichilemmal cysts have been described in English literature. Herein, we report a case of a 56-year-old lady with a nodule on the upper eyelid, with typical clinical features and characteristic histopathological findings aiding the diagnosis of trichilemmal cyst. Complete resection was performed to prevent recurrence. The authors also reviewed the cases of eyelid trichilemmal cyst reported in literature to highlight the demography, clinical features, and management of this rare eyelid tumor.<br>
