摘要

结膜痣是一种常见的结膜肿瘤。它可以出现在儿童或青少年的临床。痣的近边缘位置(颞侧和睑裂附近)是最常见的。在泪颈(眼内角)和半月襞(眼颈外)的水平出现更为罕见。它们的色素沉着随着年龄的增长而变化。因此,几乎有25%的人是无色素的(尤其是儿童)。色素沉着取决于以下几个因素:这些痣的先天性特征;怀孕期间荷尔蒙的变化;暴晒:强烈暴露在阳光下此外,在近25%的炎症病例中,或在黑色素细胞强烈活动的病例中,可以观察到色素沉着的变化。肚脐的大小会随着年龄的增长而增大。这通常发生在青春期之后。我们报告一个2岁男孩的病例,他的结膜痣长约2厘米,扁平,位于颞侧的角膜缘和球旁。眼科检查的其他部分都很正常。患儿已委托眶睑外科及附件组继续治疗。我们将介绍其临床组织学和治疗方面。

Giant Conjonctival Naevus: Case Report from Bamako
Conjunctival naevus is a common tumour in the conjunctiva. It can appear clinically in childhood or adolescence. The juxta limbic location (on the temporal side and near the palpebral fissure) of the naevus is the most frequent. Its presence at the level of the lacrimal caroncula (inner angle of the eye) and the semi-lunar fold (outside the caroncula) is more rare. Their pigmentation varies with age. Thus, almost 25% of them are amelanotic (especially in children). The pigmentation varies according to several factors: the congenital character of these naevi; hormonal changes during pregnancy; intense exposure to the sun. In addition, a change in pigmentation can be observed in almost 25% of cases with inflammation, or in cases of intense activity of melanophages. The size of the naevi tends to increase with age. This is usually done after puberty. We report a case of a 2-year-old boy with a pigmented conjunctival naevus about 2 cm long, flat, limbal and bulbar juxta at the temporal side. The rest of the eye exam is normal. The child has been entrusted to the team of the orbito-palpebral surgery and the annexes for the continuation of the management. We will present its clinico-histological and therapeutic aspects.
