How would you treat this ear lesion?

In this case discussion from Dr David Stewart, we look at a 84-year-old male patient who was seen by another physician with a new tender lesion on the rim of his helix. That physician gave him antibiotics but the lesion didn’t improve.

The patient has a history of squamous cell carcinoma and lentigo maligna.

What do you think of this lesion? What would you do next?

Update

Here is the pathology result. As the management of benign lesions is important, too, what would you do next?
