A birthmark is scientifically referred to as a naevus. This term encompasses various types of skin marks that can be present at birth or appear shortly after. A naevus can refer to pigmented lesions, such as moles, or vascular lesions, which are related to blood vessels. Understanding this term is essential in dermatology to differentiate between normal skin variations and conditions that may require attention.

In contrast, melanoma is a type of skin cancer that arises from the pigment-producing cells (melanocytes) in the skin and is important in discussions about skin health but does not describe a birthmark. A papule is a small, raised, solid pimple or swelling that is typically less than 1cm in diameter and is also not synonymous with a birthmark. A macule refers to a flat, distinct, discolored area of skin that is usually less than 1 cm wide but, like a papule, does not specifically imply a birthmark. The term naevus is the most accurate and relevant term in this context.
