Oral lymphangioma: A clinicopathological analysis of 40 cases and review of the literature

Abstract

This retrospective study aimed to perform a clinicopathological analysis of oral lymphangioma cases diagnosed at a reference service in oral pathology.A total of 40 cases with reviewed and confirmed histopathological diagnoses for oral lymphangioma were included in the study.It was found that Caucasian women represented most of the sample, with the tongue and lower lip being the most affected sites. The most frequent clinical presentation of the lesions was as an asymptomatic reddish nodule. As for morphological characteristics, there was a slight predominance of simple lymphangioma (55%). Surgical removal was the therapeutic approach adopted in most cases.Despite OL being rare, it is essential that dentists and other professionals recognize variations in the clinical presentation and histopathological aspects of these lesions, differentiating them from other vascular lesions, and implementing correct treatment in each case.
