Basal cell carinoma is the most common type of skin cancer involving the eyelid. It is also known as rodent ulcer because it was thought to be caused by bite from rat. It is associated with excessive ultraviolet exposure and usually occurs in people who work outdoor or enjoy outdoor activities such as golfer. The tumour spread by slowly eating away the surrounding normal tissue and can cause severe destruction if ignored.
This 65 year-old man presented with a lesion in the left medial canthus (area between the nose and the eye). 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 area to be excised was marked together with
the pattern of reconstruction.
Principle of OZ plasty.
At the end of surgery.
Appearance at one week post-operative.
