Atypical Cystic Carcinoma: A rare malignancy of the lower eyelid

Adenoid cystic carcinoma (ACC) is a rare malignancy of the secretory glands, most commonly originating in the lacrimal gland but rarely involving the eyelids. ACC is known for its aggressive behaviour, high recurrence rate, and potential for metastasis, leading to a poor prognosis. Histopathological examination is essential for the diagnosis, and early detection with complete excision offers the best chance for a favourable outcome. This case highlights the importance of comprehensive management to reduce the recurrence risk and improving patient survival. The authors present a 56-year-old man with ACC of the left lower eyelid, who underwent surgical excision followed by reconstruction, ensuring tumour-free margins.
