Sebaceous cell carcinoma is a rare tumour that accounts for 1% to 5% of malignant eyelid tumours in white populations.1 However, in East and South Asian populations in which basal cell carcinoma is less frequent, sebaceous cell carcinoma is more frequent. A recent review of malignant eyelid tumours in Western Kowloon, Hong Kong, reported that 11.1% of their tumours were sebaceous cell carcinoma.2 It originates in meibomian glands and glands of Zeis.3 Most commonly found on the upper and lower eyelids, it can masquerade as chronic unilateral blepharitis, recurrent chalazia, basal cell carcinoma, or sebaceous cell carcinoma.
