How would you manage this lesion on the finger?

In this week's case discussion, we revisit a presentation submitted by Dr Cheh Goh, in which a 45-year-old male patient comes in with a lesion on his finger.

The lesion has been present for around two months and is expanding. The patient has no history of skin cancer.

What do you think, and how would you approach treatment?
