Oral lymphatic malformations are uncommon lesions. This study assessed the clinicopathological and sociodemographic features of oral lymphatic malformations in a Brazilian oral pathology service. Between 2000 and 2021, all oral lymphatic malformations diagnosed in a single oral pathology service were selected for the study. Clinical data, such as age, sex, site of the lesion, clinical presentation, diagnosis clinical, and the type of biopsy were recorded from the patient's clinical charts. From 7554 oral lesions, 17 (0.22%) were oral lymphatic malformations. This lesion similarly affected both sexes, and the mean age of the patients was 16.5 years. The tongue was the most common site (n = 13; 76%). The mean size of the lesions was 17 mm. Oral lymphatic malformations were asymptomatic for 29% of the patients. Clinically, most lesions appeared as a reddish, sessile nodule, with a pebbly surface. In addition, the clinical and histopathological diagnoses agreed for most lesions (n = 11; 64%). The type of biopsy performed was excisional in 41% of lesions. In summary, oral lymphatic malformations present a low prevalence among the oral lesions diagnosed in an oral pathology service. Moreover, they affect equally both sexes, especially young patients, and usually appear as an asymptomatic or symptomatic nodular swelling on the tongue.
口腔淋巴管畸形较为罕见。本研究评估了巴西口腔病理服务中心口腔淋巴管畸形的临床病理和社会人口学特征。在 2000 年至 2021 年期间，从单一的口腔病理服务中心选择所有诊断为口腔淋巴管畸形的病例进行研究。从患者的临床图表中记录了临床数据，如年龄、性别、病变部位、临床表现、临床诊断以及活检类型。在 7554 例口腔病变中，有 17 例（0.22%）为口腔淋巴管畸形。该病变同样影响两性，患者的平均年龄为 16.5 岁。最常见的病变部位是舌（n=13；76%）。病变的平均大小为 17mm。29%的患者的口腔淋巴管畸形无症状。临床上，大多数病变表现为红色、无蒂结节，表面呈鹅卵石状。此外，大多数病变的临床和组织病理学诊断相符（n=11；64%）。41%的病变采用了切除性活检。总之，口腔淋巴管畸形在口腔病理服务中心诊断的口腔病变中患病率较低。此外，它们同样影响两性，尤其影响年轻患者，通常表现为无症状或有症状的舌部结节性肿胀。
