A 65 year-old man presented with a lesion in the left medial canthus. The lesion had been present for the past 9 months and had got progressively bigger and bled easily on scratching. The feature was suggestive of basal cell carcinoma. The lesion was excised with a 3 mm margin. The histology confirmed basal cell carcinoma with tumour-free margins. The defect was covered with an O-Z plasty as shown.

The upper eyelid also had a co-existing naevus which was excised simultaneously.   The lesion was excised with a 3mm margin and an O-Z plasty used to reconstruct the defect.   The eye at one-day post-operative.   The eye at one-week post-operative.   Apparent of the eye at two-week post-operative.
