Massa Periokular Kongenital pada Anak: Laporan Kasus Kista Dermoid Palpebra

Dermoid cyst is a benign congenital choristoma frequently found in the periocular region, particularly in children. It results from ectodermal tissue sequestration along embryonic fusion lines. Although generally benign and slow-growing, dermoid cysts may cause cosmetic deformity, mechanical ptosis, or visual disturbance if left untreated. A 4-year-old child presented with a painless, slowly enlarging mass on the upper eyelid that had been noticed since early childhood. Physical examination revealed a well-circumscribed, firm, non-tender mass without signs of inflammation. Visual acuity was within normal limits, and no proptosis was observed. Clinical findings were consistent with a superficial eyelid dermoid cyst. The patient underwent complete surgical excision under general anesthesia. Intraoperatively, the cyst was removed intact without rupture. Histopathological examination confirmed a dermoid cyst characterized by keratinized stratified squamous epithelium lining with adnexal skin structures. Postoperative recovery was uneventful, with good cosmetic outcome and no recurrence during follow-up. Eyelid dermoid cyst can be diagnosed clinically through careful history taking and physical examination. Complete surgical excision is the definitive treatment and provides excellent functional and cosmetic outcomes. Early management is recommended to prevent potential complications and to achieve optimal results.
