Sialolithiasis is a pathological process that affects the major salivary glands. It consists of calcifications that obstruct the parenchyma of the gland and / or the lumen of the ducts. The 37 years old female patient, VBB, leucoderma, attended the stomatology service with a complaint of swelling in the floor of mouth, which she noticed 10 years ago. The clinical and radiographic exams indicated a diagnosis of multiple sialolithiasis in the left submandibular gland duct. Surgical intervention was indicated in this case. Amongst all sialolithiasis cases, 80% affect the submandibular glands. Of these, 70% are isolated sialoliths. Only 5% of cases present more than 3 calcifications. This study aims to report the diagnosis and treatment of a rare case of multiple sialoliths located in the duct of the submandibular gland, which were surgically removed via intraoral access. RESUMO Sialolitíase é um processo patológico que acomete as glândulas salivares maiores e consiste em calcificações que obstruem o parênquima da glândula e/ou a luz dos ductos. A paciente VBB do sexo feminino, leucoderma, 37 anos, compareceu ao serviço de estomatologia com a queixa de aumento de volume do assoalho bucal esquerdo iniciado a 10 anos. Com os exames clínicos e radiográficos fechou-se o diagnóstico de uma condição rara de sialolitíase múltipla no ducto da glândula submandibular esquerda com indicação de tratamento cirúrgico. 80% dos casos de sialolitíase acometem as glândulas submandibulares e 70% são cálculos únicos. Apenas 5% dos casos apresentam mais de 3 calcificações. O presente trabalho tem como objetivo relatar um caso raro de sialolito múltiplo localizado no ducto da glândula submandibular e tratado através de remoção cirúrgica com acesso intraoral.

Sialolithiasis, or salivary calculus, is a disease of the salivary glands, characterized by the formation of mineralized structures within the excretory salivary ducts or the glandular parenchyma. Approximately 80% occur in the submandibular gland, followed by the parotid and sublingual glands. Although rare, sialolithiasis can also occur in the minor salivary glands. Although the oral cavity and upper lip are the most common sites, they can develop in any region of the oral cavity that contains minor salivary glands. Treatment is based on surgical excision of the lesion, with a favorable prognosis. This study presents three cases of sialolithiasis of minor salivary glands of the upper and lower lip, addresses their clinical characteristics and correlation with microscopic findings, diagnosis and treatment plans. Etiology and factors that should be considered during diagnosis, appropriate treatment and improved prognosis are discussed in this study. A sialolitíase, ou cálculo salivar é uma doença de glândulas salivares, caracterizada pela formação de estrutura mineralizada no interior dos ductos salivares excretores ou no próprio parênquima glandular. A glândula submandibular é acometida em aproximadamente 80% dos casos seguida das glândulas parótida e sublingual. Embora raro o cálculo salivar também pode ocorrer em glândulas salivares menores. O lábio superior e a mucosa oral são os sítios de envolvimento de maior frequência, embora possam desenvolver-se em qualquer região da cavidade oral que contenha glândulas salivares menores. O tratamento baseia-se na remoção cirurgia, com prognóstico favorável. Este artigo apresenta três casos raros de sialolitíase de glândula salivar menor localizados em lábio superior e inferior, abordando as características clínicas e sua relação com os achados microscópicos, diagnóstico e formas de tratamento. A etiologia da lesão e fatores que devem ser considerados para o diagnóstico, tratamento adequado e um melhor prognóstico são discutidos neste estudo.
