Dermoscopic Changes in Melanocytic Naevi in Children during Digital Follow-up

Abstract

The aim of this study was to investigate the dermoscopic changes in acquired melanocytic naevi in a large paediatric population over an interval of several years. Images of 717 melanocytic naevi were obtained from 160 consecutive patients. Dermoscopic pigment pattern changes were observed in one of two lesions after a follow-up of one year, in 34 of 295 lesions (11.5%) after 2 years, in 40 of 190 lesions (21.1%) after 3 years, in 40 of 141 lesions (28.4%) after 4 years, in 5 of 37 lesions (13.5%) after 5 years, in 12 of 31 lesions (38.8%) after 6 years, and in 7 of 21 lesions (33.3%) after 7 years. Dermoscopic changes were detected in 25.3% of the lesions in patients aged 3-6 years, in 21% of the lesions in patients aged 7-12 years, and in 15.5% of the lesions in patients over 13 years. Main pattern changes consisted of transition from globular to globular-reticular (35 naevi), from globular to reticular (14 naevi) and from globular-reticular to reticular (24 naevi). These results are consistent with the view that melanocytic naevi generally undergo a characteristic transition from a globular pattern to a reticular pattern. Most of the changes are observed in the 3-6 years age group when hormonal and/or environmental factors are not thought to play a role in pattern alterations.

Divided or kissing nevus of the penis: A new case with dermoscopic findings

“…To our knowledge, this is the first report of dermoscopic changes in a divided nevus of the penis over time. The changes we have observed—from globular to globular‐reticular pattern—are in accord with those observed in other nevi …”

“…The changes we have observed-from globular to globular-reticular pattern-are in accord with those observed in other nevi. 16 The risk of malignant transformation of kissing nevus of the penis seems to be low, having been observed in only one case. 14 Therefore, aesthetics and functionality are primary considerations in the management of these patients.…”

The study of nevi in children: Principles learned and implications for melanoma diagnosis

“…12,31,37 A similar trend was observed in a pediatric cohort study from Italy. 38 Cross-sectional analysis of the dermoscopic patterns of nevi on the trunk by age is consistent with these longitudinal observations (Table 1). …”

An advanced design of non-radioactive image capturing and management system for applications in non-invasive skin disorder diagnosis

“…The developed image capturing system was found to be able to provide quality dermoscopic images helpful for the differentiation of melanocytic from non-melanocytic lesions as well as for the analysis of dermoscopic features. Specifically, we identified typical melanocytic patterns (globular and reticular pattern [11]) in melanocytic naevi, and absence of melanocytic patterns in all haemangiomas. The presented two-step analysis algorithm of skin lesions confirmed the findings on clinical inspection and provided a standard approach to dermoscopic examination even in difficult cases.…”
