Giant Conjonctival Naevus: Case Report from Bamako

Abstract

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.
