Abstract

Mastocytosis is an accumulation of clonal mast cells within tissues, commonly caused by mutations in the KIT proto-oncogene. This report describes the management of a neonate with diffuse cutaneous mastocytosis (DCM) caused by a rare activating KIT mutation, specifically internal tandem duplication of the Ala502Tyr503 pair on exon 9, and reviews current data regarding work-up of DCM in pediatric patients.

摘要

肥大细胞增多症是指克隆性肥大细胞在组织内积聚，通常由KIT原癌基因突变引起。本报告描述了一名患有弥漫性皮肤肥大细胞增多症（DCM）的新生儿的治疗情况，该病症由一种罕见的KIT激活突变导致，具体为第9外显子上Ala502Tyr503对的内部串联重复，并回顾了有关儿科患者DCM检查的当前数据。
