This is the classic description of a basal cell carcinoma (BCC), the most common type of skin cancer. Look out for a skin-coloured or pink nodule with a central depression, pearly rolled edge, and surface telangiectasia. BCC's are unlikely to cause any pain or bleeding and are very slow growing. They are usually located on sun-exposed areas of skin, hence the lesion in this question appearing on the patient's neck.

Actinic keratoses are premalignant lesions that often appear before the development of squamous cell carcinoma. Unlike BCCs, they present as a thickened papule or plaque with surrounding erythematous skin. They have a rough warty surface and can cause pruritus. They are also typically found on sun-exposed skin.

Squamous cell carcinomas (SCCs) appear as irregular, ill-defined red nodules. They often appear scaly and ulcerated. They can cause pain and bleeding and can grow over weeks to months. Similarly to BCC's, they typically appear on sun-exposed skin such as on the face, scalp, ears, and hands.
