The RCM criteria of most types of melanocytic nevi have been extensively described in the literature within the past years [1–4]. This chapter complements this body of knowledge by describing the RCM features of less frequent types of nevi, namely blue, “black” and recurrent nevi.Common to these nevus variants is that they are often the clinical outlier or “ugly duckling” among the patient’s moles, and as such, these nevi tend to raise some clinical concern; moreover, their dermoscopic features are often equivocal. To this end, RCM can reveal additional architectural and cellular details about these nevi, and thus can serve as a helpful adjunct for diagnosis and management decision. In the following sections, we describe the RCM features of these nevi in the context of the current technical limitations of RCM, such as the restricted depth of penetration of light and the limited cellular details.
