Dermoscopic Features of Congenital Melanocytic Nevus and Becker Nevus in an Adult Male Population: An Analysis with a 10-Fold Magnification

Abstract: Background: Dermoscopic features of congenital melanocytic nevi (CMN) have been mostly assessed by high-resolution videodermoscopy. However, optical dermoscopy with the 10-fold magnification is largely available. In some instances, the differential diagnosis between large CMN and Becker nevus (BN) may be difficult. Objective: The aims of this work were: (1) to assess by dermoscopy with the 10-fold magnification the morphological features which have been previously suggested as useful for the identification of … Show more

“…Many of these structures have been previously described as common features of CMN. [7][8][9]12,15 If the dermoscopic appearance of the lesion revealed that a single pattern was present in greater than one-third of the total area of the lesion, that lesion was classified as having 1 of the following 5 predominant dermoscopic patterns: reticular, globular, reticuloglobular, diffuse background pigment with or without remnant structures, or other. A reticular pattern was defined as a primarily reticular pattern, a globular pattern was defined as a primarily globular pattern, and a reticuloglobular pattern was defined as peripheral reticulation with central globules.…”

“…We note that this network has been previously described as a reticular network centered by a dot. [7][8][9] However, a variety of different structures, such as dots, globules, and vessels, may occupy the spaces of a reticular network ( Figure 5). Because the spaces of the network have a targetlike appearance in each case, strictly speaking, a network may be accurately described as a target network regardless of the exact type of structure present.…”

“…A recent retrospective study of 118 children in Italy with a diagnosed Becker nevus showed a nearly equal distribution among sexes (47 % male) in contrast to the common assumption of predominance in adolescent males [62]. Hypertrichosis also was present in only one-third of cases as compared to the presence of terminal hairs in the Becker nevi of 70 % of young Italian men [63]. The authors attribute this observation to the young age of the study patients, many of whom were preadolescent and thus had not experienced prominent hormone changes.…”
