What is the term for a cluster of pigmented skin cells that can be raised or flat?

Explanation:
A nevus is a benign collection of pigmented skin cells that forms a mole. These moles can appear flat (junctional) or become raised as they grow (compound or intradermal), reflecting how the pigmented cell clusters sit in the skin. Lentigines, by contrast, are flat spots due to increased pigment, not a discrete nest of pigment cells; melanomas are malignant tumors that arise from melanocytes and often show irregular, evolving features; carotene deposits cause a yellow-orange skin color from pigment in the diet rather than a cluster of pigmented cells. So the term that best fits a cluster of pigmented skin cells that can be either raised or flat is nevus.
