Click to identify the basal cell carcinoma in the image above:

Here is a small nodule at the edge of the lower eyelid. This is the most common malignant neoplasm of the eyelid, and it arises in the setting of sun damage. The nodule has a central rounded ulceration and raised pink margins. This is a basal cell carcinoma. A BCC is slow growing, but in this location presents a problem in removal because you need to get adequate margins while leaving enough eyelid to be functional.
