The presence of a raised lesion with a small perforator under the nose is indicative of a nasal dermoid cyst. These lesions often present in the midline of the face, particularly in areas such as the nasion, premaxilla, or just beneath the nose. They can become noticeable due to their growth, leading to a raised appearance, and the small perforator could represent a sinus tract that communicates with the skin surface.

This anatomical location is especially common for dermoid cysts due to embryological development, where skin and contents can become trapped during fetal development. Other locations like the forehead, eyelid, or scalp can have raised lesions, but they are less characteristic of issues like dermoid cysts or similar entities specifically found in the midline facial region. Hence, the under-nose area is more accurately associated with these types of lesions because of the potential for such cystic formations and their unique presentation patterns.
