Adenoid Cystic Carcinoma of the Upper Eyelid: A Rare Case Report

Adenoid cystic carcinoma is a sporadic, locally aggressive, and highly recurrent malignant epithelial tumor accounting for 1% of all head and neck cancers. It primarily affects minor and major salivary glands and has a high tendency of local invasion and distant metastasis. It uncommonly originates from the palpebral portion of the lacrimal gland in the orbit. In this case report, we present a 30-year-old female patient who complained of a painless nodule in the left upper eyelid, which initially was of pea size; over time, the swelling increased to the present size. The swelling was then excised and sent for histopathological examination. Histopathological examination revealed tumor cells arranged in cribriform and tubular patterns, and finally, the diagnosis of Adenoid cystic carcinoma was made.
