Abstract

Congenital epulis of the newborn is a very rare and unique tumor first described in 1871 by Neuman. It has a female predilection. It is a tumor with no tendency to recur after excision. The histogenesis of the lesion is unknown, but it is believed to be of mesenchymal origin. We report a 2-day-old female with tumor mass on the anterior mandibular alveolar ridge, which demonstrated immunoreactivity for vimentin, S-100 and neuron-specific enolase; thus, suggesting a similar histogenesis with granular cell tumor.

摘要

新生儿先天性牙龈瘤是一种非常罕见且独特的肿瘤，1871年由纽曼首次描述。它好发于女性。这是一种切除后无复发倾向的肿瘤。该病变的组织发生学尚不清楚，但据信起源于间充质。我们报告一例2日龄女性，其下颌前牙槽嵴有肿瘤肿块，该肿块对波形蛋白、S-100和神经元特异性烯醇化酶呈免疫反应性；因此，提示其组织发生学与颗粒细胞瘤相似。
