Malignant tumours affecting the eyelid include basal cell carcinoma (85% to 95%), squamous cell carcinoma (approximately 5%), sebaceous carcinoma (1% to 5%), and malignant melanoma (1%). Non-Hodgkin’s lymphoma of the eyelid is rare. This report is of an 80-year-old woman who presented with diffuse left upper eyelid swelling, clinically suspected to be a haemangioma. Rare diseases should be considered in differential diagnoses because they have the potential for rapid systemic involvement and may need treatment that is different from that of other common diseases at the same site.
