What is a benign skin condition that can be found anywhere, characterized by being scaly, hard, slightly raised, and pinkish-brown?

The condition described in the question matches the characteristics of a dermatofibroma. Dermatofibromas are benign tumors of the skin that typically present as firm, raised nodules. They often have a scaly surface and can appear pinkish-brown in color. Their hardness and slightly raised appearance help to distinguish them from other skin lesions. They are commonly found on the legs but can occur anywhere on the body, aligning with the description provided that it can be found "anywhere."

In contrast, keratoacanthomas often present as dome-shaped lesions that can have a central keratin plug and have a more rapid growth pattern compared to dermatofibromas. Acrochordons, commonly known as skin tags, are soft, benign growths that hang from the skin and are not typically raised or scaly. Epidermal cysts, also known as sebaceous cysts, are firm lumps beneath the skin filled with keratin but do not have the scaly texture associated with dermatofibromas. Each of these conditions has distinct features that differ from the description of the benign skin condition mentioned in the question.
