Naevus spilus-type congenital melanocytic naevus associated with a novel NRAS codon 61 mutation


Krengel, S; Widmer, D S; Kerl, K; Levesque, M P; Schiestl, C; Weibel, L (2016). Naevus spilus-type congenital melanocytic naevus associated with a novel NRAS codon 61 mutation. British Journal of Dermatology, 174(3):642-644.

Abstract

We recently described 17 patients with a new subtype of congenital melanocytic naevi (CMN), designated as "naevus spilus-type CMN" (1). The affected patients present with a large café-au-lait (CAL) background macule and dozens of superimposed small and medium-sized CMN. Here we report an additional case with a novel NRAS mutation (Q61L). CMN are categorized by their largest diameter (projected adult size, PAS) (2). Small CMN (SCMN, <1.5 cm PAS) and medium-sized CMN (MCMN, 1.5 - 20 cm PAS) represent rather common, solitary, slightly thickened plaques with prominent terminal hairs.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
