Patients with numerous melanocytic nevi, i.e. those who are moley, often produce a particular type of nevus, a so-called signature nevus.  Examples of the various types of signature nevi include solid brown, solid pink (especially in skin type I individuals), black with thin brown rim (representing junctional and compound lentiginous nevi), cockarde, and even multiple halo nevi; the latter are seen most commonly in teenagers and young adults who have an increased number of truncal nevi.  Another type of signature nevus is the “eclipse nevus” which is characterized by a tan center and brown rim.  The brown rim may be irregular in outline, even stellate, hence the name eclipse.  This type of nevus is commonly seen on the scalp of children who are destined by hereditary factors to become moley.  Recognition of an individual’s signature nevus and its clinical spectrum allows the dermatologist to focus on those nevi that do not fit the “pattern” and thereby become less overwhelmed by the sheer number of nevi in a particular patient.
