Management and dermoscopy of fast-growing nevi in pregnancy: case report and literature review.

The relationship between pregnancy and a change in melanocytic nevi is still controversial. Moreover, management of the rapid evolution of a nevus in an unauspicious melanocytic lesion can be a clinical challenge in pregnancy.This article examines a case of a fast-growing deep penetrating nevus in a pregnant woman and provides a literature review of articles relative to pregnancy and nevi change, the management of fast-growing pigmented lesions, and the role and usefulness of dermoscopy in these cases.Recent studies have documented that pregnancy is not associated with any significant change in the size of melanocytic nevi. The management of fast-growing melanocytic lesions during this period compulsorily leans toward excision. Dermoscopy can be useful, providing clinicohistopathologic correlations and a better assignment of the lesion.This case report and review provide important management considerations for nevi during pregnancy. Early intervention with aggressive treatment measures is the best management for fast-growing lesions, and epiluminescence dermoscopy can assist the management, although still remaining a second-level examination, useful for documentation and for a better classification of the lesion.
