Sebaceous gland carcinoma of the lid.

At the Montreal General Hospital over the past 15 years five sebaceous gland carcinomas of the lid (3.5% of all malignant tumours of the lid) were diagnosed and treated. The five cases illustrate well the different clinical presentations of these tumours, knowledge of which is essential for early diagnosis. Once the diagnosis is suspected, a full-thickness lid biopsy is required. Management should then consist of wide excision, with preparation of frozen sections during the operation to ensure tumour-free borders.
