Final answer:
Basal cell carcinoma is the lesion known for having a distinctive erythematous border. It is the most common skin cancer and occurs in the basal cells of the epidermis, typically presenting as a pearly bump or an uneven growth.
Step-by-step explanation:
The lesion with a distinctive erythematous border is Basal cell carcinoma. Basal cell carcinoma is a form of skin cancer that originates in the basal cells of the epidermis, which are stem cells that divide to form all the keratinocytes of the epidermis. It is the most common type of skin cancer in the United States. It may present as a pearly or waxy bump but can also appear as an uneven patch, bump, growth, or scar with a distinctive erythematous border on the skin surface. Basal cell carcinomas are generally localized and are best treated when caught early, with treatment options including surgery, freezing (cryosurgery), and topical ointments.

Basal cell carcinomas start in the stratum basale and usually spread along this boundary, appearing as an uneven patch, bump, growth, or scar on the skin surface.
