Recent progress in the treatment of intractable sialolithiasis / 北京大学学报(医学版)

Sialolithiasis occurs in approximately 0.45% to 1.20% of the general population. The typical clinical symptom manifests as a painful swelling of the affected glands after a meal or upon salivary stimulation, which extremely affects the life quality of the patients. With the development of sialendoscopy and lithotripsy, most sialoliths can be successfully removed with preservation of the gland. However, sialoliths in the deep hilar-parenchymal submandibular ducts and impacted parotid stones located in the proximal ducts continue to pose great challenges. Our research center for salivary gland diseases (in Peking University School and Hospital of Stomatology) has used sialendoscopy for 17 years and treated >2 000 patients with salivary gland calculi. The success rate was approximately 92% for submandibular gland calculi and 95% for parotid calculi. A variety of minimally invasive surgical techniques have been applied and developed, which add substantial improvements in the treatment of refractory sialolithiasis. Further, the radiographic positioning criteria and treatment strategy are proposed for these intractable stones. Most of the hilar-parenchymal submandibular stones are successfully removed by a transoral approach, including transoral duct slitting and intraductal basket grasping, while a small portion of superficial stones can be removed by a mini-incision in submandibular area. Impacted stones located in the distal third of parotid gland ducts are removed via "peri-ostium incision", which is applied to avoid a cicatricial stenosis from a direct ostium incision. Impacted parotid stones located in the middle and proximal third of the Stensen's duct are removed via a direct mini-incision or a peri-auricular flap. A direct transcutaneous mini-incision is commonly performed under local anesthesia with an imperceptible scar, and is indicated for most of impacted stones located in the middle third, hilum and intraglandular ducts. By contrast, a peri-auricular flap is performed under general anesthesia with relatively larger operational injury of the gland parenchyma, and should be best reserved for deeper intraglandular stones. Laser lithotripsy has been applied in the treatment of sialolithiasis in the past decade, and holmium ∶YAG laser is reported to have the best therapeutic effects. During the past 3 years, our research group has performed laser lithotripsy for a few cases with intractable salivary stones. From our experiences, withdrawal of the endoscopic tip 0.5-1.0 cm away from the extremity of the laser fiber, consistent saline irrigation, and careful monitoring of gland swelling are of vital importance for avoidance of injuries of the ductal wall and the vulnerable endoscope lens during lithotripsy. Larger calculi require multiple treatment procedures. The risk of ductal stenosis can be alleviated by endoscopic dilation. In summary, appropriate use of various endoscopy-assisted lithotomy helps preserve the gland function in most of the patients with refractory sialolithiasis. Further studies are needed in the following aspects: Transcervical removal of intraglandular submandibular stones, intraductal laser lithotripsy of impacted parotid stones and deep submandibular stones, evaluation of long-term postoperative function of the affected gland, et al.

Sialolitiasis, sialoadenitis y sialoadenosis. Revisión de literatura y reporte de un caso clínico / Sialolithiasis, sialadenitis and sialadenosis. Review of literature and report of a clinical case

Introducción: la formación de sialolitos se considera la alteración más común en las glándulas salivales. Su origen aún no es claro en cuanto a qué provoca la obstrucción parcial o total del sistema de conductos salivales, con una predilección significativa en las glán - dulas submandibulares, lo que permite un desplazamiento retrógrado de bacterias a través del conducto salival hacia la glándula afectada, el cual se traducirá clínicamente como inflamación unilateral o bila - teral. El tratamiento para la sialolitiasis y sialoadenitis puede variar desde un manejo conservador hasta tratamientos que implican la remoción de la glándula salival afectada. La sialoadenosis difiere de las anteriores en su origen, ya que ésta no se considera inflamatoria ni neoplásica y no afecta la función glandular de excretar saliva. Presentación de caso clínico: se trata de paciente masculino con diagnósticos presuntivos de sialoadenitis y sialolitiasis, al cual se le realizó biopsia escisional de la glándula afectada, su estudio histo- patológico corroboró los diagnósticos mencionados anteriormente que además confirmó un diagnóstico de sialoadenosis. Conclusio- nes: la escisión de la glándula salival involucrada se realizará en casos diagnosticados de sialoadenitis y sialolitiasis con sialolitos de gran tamaño y procesos supurativos crónicos que no resuelven con antibioticoterapia (AU)

Introduction: Sialoliths are mineralized lesions in the salivary glands that cause total or partial obstruction of the duct, commonly affecting the submandibular gland. It ranges from less invasive to surgical approach, depending on the number, location and dimension of the calculi. Objective: This study aimed to report a rare clinical case of a sialolith in the parotid gland's duct treated by surgical removal. Case Report: The patient attended the outpatient clinic with a history of pain and edema in the face with 2 months of evolution, reporting worsening symptoms after feeding. On physical examination, he had hardened edema in the left preauricular region and no drainage in the ipsilateral parotid duct. Soft tissue radiography with a periapical film was performed, which revealed a circumscribed radiopaque image suggestive of a sialolith in the left parotid gland's duct. Thus, the calculus's surgical excision was performed, followed by the reestablishment of the ductal patency through the installation of a venous catheter. The patient evolved well and is being followed up without recurrence of signs and symptoms. Final Considerations: The present study reveals that the early diagnosis of sialolithiasis and the choice of the appropriate treatment plan are associated with a good prognosis, and the reestablishment of ductal patency, when damaged, is essential for the success of the treatment(AU)

Introdução: O sialolito é a patologia mais frequente nas glândulas salivares maiores, ocorrendo em maior prevalência na glândula submandibular. Os sinais e sintomas clínicos incluem edema e dor na região da glândula acometida pelo sialolito e em caso de obstrução do ducto, os sintomas são mais pronunciados. Existem diversas alternativas de tratamento para a sialolitíase, com indicações específicas de acordo com cada caso. Desse modo, o objetivo desse artigo é relatar a técnica cirúrgica utilizada para remover um grande sialolito localizado no parênquima de glândula salivar maior. Relato de Caso: Paciente do sexo feminino, 49 anos, melanoderma, com queixas álgicas à palpação da região submandibular direita, há aproximadamente oito meses, apresentando discreto aumento de volume enrijecido no local. Ao exame de imagem foi observada imagem radiopaca na região, sugerindo a presença de sialollito no interior da glândula submandibular direita. Conclusão: Diversas modalidades de tratamento são descritas para sialolitíase. O tratamento conservador e/ou minimamente invasivo está indicado para cálculos de pequena dimensão ou extraglandulares e inclui a ordenha da glândula afetada. Cálculos maiores, localizados no interior da glândula, requerem tratamentos mais radicais, e na maioria das vezes, a excisão cirúrgica da glândula é o tratamento de escolha.

Introduction: Sialolith is the most frequent pathology in the major salivary glands, occurring in greater prevalence in the submandibular gland. Clinical signs and symptoms include swelling and pain in the region of the compromised gland by the sialolith and in case of duct obstruction, the symptoms are more evident. There are several treatment alternatives for sialolithiasis, with specific indications according to each case. Thus, the aim of this article is to report the surgical technique used to remove a large sialolith located in the greater salivary gland parenchyma. Case Report: Female patient, 49 years old, black, with complaints of pain on palpation of the right submandibular region, for approximately eight months, with a slight increase in the hardened volume at the site. The imaging exam showed a radiopaque image in the region, suggesting the presence of sialolith in the right submandibular gland. Conclusion: Several treatment modalities are described for sialolithiasis. Conservative and/or minimally invasive treatment is indicated for small or extraglandular calcifications and includes milking of the compromise gland. Larger stones, located inside the gland, require more radical treatments, and most of the time, surgical excision of the gland is the treatment of choice.

Introduction: sialolithiasis is the most common form of obstructive sialadenitis caused by a mixture of different calcium phosphates and an organic matrix. It is one of the most common salivary gland diseases, often attributed to the submandibular gland, with no relation to age or gender. However, it is rarely reported in the minor salivary glands. Objective: the present study aims to report auncommon clinical finding case of a sialolithiasisof minor salivary gland in labial mucosa. Case report: a 43-year-old female patient presented with a single, yellow and asymptomatic nodule in the labial mucosa at clinical examination. The clinical hypotheses were lipoma and fibrous hyperplasia. The lesion was biopsied, and the histopathological analysis showed a mineralized tissue. The final diagnosis was sialolithiasis and the patient remained under follow-up (8 months) without relapse. Conclusion: this case shows that sialolithiasis should be included in the diagnostic hypotheses when occur in a minor salivary glands area and emphasizes the importance of a complete clinical examination since it was not complaint of the patient.(AU)

Introdução: a sialolitíase é a forma mais comum de sialadenite obstrutiva causada por um composto de diferentes produtos, como fosfato de cálcio e matriz orgânica. É uma das doenças mais comuns das glândulas salivares, geralmente atribuídas à glândula submandibular, sem relação com idade ou sexo. No entanto, raramente é relatada nas glândulas salivares menores. Objetivo: reportar um achado clínico incomum de sialolitíase em glândula oral menor na mucosa labial. Relato de caso: uma paciente do sexo feminino, de 43 anos, apresentou nódulo único, amarelo e assintomático na mucosa labial durante o exame clínico. As hipóteses clínicas foram lipoma e hiperplasia fibrosa. A lesão foi encaminhada para biópsia e a análise histopatológica mostrou um tecido mineralizado. O diagnóstico final foi de sialolitíase e o paciente permaneceu em acompanhamento por 8 meses sem recidiva. Conclusão: este caso mostra que a sialolitíase deve ser incluída nas hipóteses diagnósticas de lesões em áreas de glândulas salivares menores e enfatiza a importância de um exame clínico completo, pois não se tratava da queixa principal da paciente.(AU)

Salivary Gland Disorders in Children and Adolescents: A 15-year Experience

Abstract Introduction Diseases of the salivary glands are rare in children and adolescents, with the exception of viral-induced infections. Objective To determine the clinical course of the disease, the diagnostic procedures, the treatment and the outcome of all children and adolescents affected with salivary gland diseases at our clinic over a period of 15 years. Methods A retrospective chart review including a long-term follow-up was conducted among 146 children and adolescents treated for salivary gland disorders from 2002 to 2016. Results Diagnosing acute sialadenitis was easily managed by all doctors regardless of their specialty. The diagnosis of sialolithiasis was rapidly made only by otorhinolar- yngologists, whereas diagnosing juvenile recurrent parotitis imposed difficulties to doctors of all specialties - resulting in a significant delay between the first occurrence of symptoms and the correct diagnosis. The severity-adjusted treatment yielded improve- ments in all cases, and a full recovery of 75% of the cases of sialolithiasis, 73% of the cases of juvenile recurrent parotitis, and 100% of the cases of acute sialadenitis. Conclusions Due to their low prevalence and the lack of pathognomonic symptoms, salivary gland diseases in children and adolescents are often misdiagnosed, resulting in an unneces- sarily long period of suffering despite a favorable outcome following the correct treatment.

Efectividad de la succión desembrozante en pacientes con procesos inflamatorios de las glándulas salivales mayores / Effectiveness of the depleting suction in patients with inflammatory processes of the major salivary glands

Introducción: Las inflamaciones agudas y crónicas pueden afectar las glándulas salivales mayores. Objetivo: Evaluar la evolución de los pacientes con procesos inflamatorios de las glándulas salivales mayores tratados con succión desembrozante. Métodos: Se realizó un estudio descriptivo de 49 pacientes con procesos inflamatorios de las glándulas salivales mayores, atendidos en la consulta de Cirugía Maxilofacial del Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba, desde septiembre del 2012 hasta junio del 2014. Se utilizó la aspiración quirúrgica para succionar los conductos de las glándulas salivales afectadas. Se estudiaron variables, tales como edad, sexo, glándula salival afectada, agente causal, sintomatología, sesiones de tratamiento y evolución ultrasonográfica. Resultados: Predominaron el grupo etario de 65 años y más (36,7 %) y el sexo femenino (59,2 %). La litiasis fue el factor causal de mayor incidencia y la glándula parótida la más afectada. Los pacientes evolucionaron satisfactoriamente luego de la segunda succión, lo cual demostró la existencia de cambios ultrasonográficos favorables. Conclusiones: La succión desembrozante es un procedimiento sencillo e inocuo que evita el proceder quirúrgico.

Introduction: The acute and chronic inflammations can affect the major salivary glands. Objective: To evaluate the clinical course of patients with inflammatory processes of the major salivary glands treated with depleting suction. Methods: A descriptive study of 49 patients with inflammatory processes of the mayor salivary glands was carried out, they were assisted in the Maxillofacial Surgery service of Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba, from September, 2012 to June, 2014. The surgical aspiration was used to suck the tubes of the affected salivary glands. Some variables were studied, such as age, sex, affected salivary gland, causal agent, symptomatology, treatment sessions and ultrasonographic course. Results: There was a prevalence of the 65 and over age group (36.7 %) and the female sex (59.2 %). Lithiasis was the causal factor of more incidence and the parotid gland the most affected one. Patients had a favorable clinical course after the second suction, which demonstrated the existence of favorable ultrasonographic changes. Conclusions: Depleting suction is a simple and innocuous procedure that avoids operation.

Introdução: Os sialolitos são calcificações, que ocorrem no interior dos ductos ou nas glândulas salivares. De origem desconhecida, tal afecção constitui uma das mais comuns, que acometem as glândulas salivares, podendo ter tamanhos diversos e localizações. Os sialolitos maiores de 15 mm são considerados raros, podendo gerar uma diminuição da qualidade de vida do paciente em virtude de alterações funcionais da glândula salivar acometida. O diagnóstico de tal afecção é realizado por meio do exame clínico associado a radiografias e, se necessário, tomografia computadorizada na busca de uma maior elucidação do caso. Atualmente, existem diversas modalidades de tratamento para os sialolitos, que irá depender de sua localização e dimensões, variando desde tratamento conservador, com utilização de hidratação e sialogogos à remoção cirúrgica do sialolito. Relato de caso: Este artigo científico tem como objetivo relatar o caso clínico de um raro sialolito de aproximadamente 37 mm, localizado no ducto de Wharton em paciente geriátrico. O caso foi conduzido por remoção cirúrgica do sialolito com a confecção de uma nova desembocadura para o ducto.

(AU)

Introduction: Sialoliths are calcifications that occur within the ducts or in the salivary glands. Of unknown origin, this condition is one of the most common that affects the salivary glands and may have different sizes and locations. Sialoliths larger than 15 mm are considered rare, and may lead to a reduction in the quality of life due to functional alterations of the affected salivary gland. The diagnosis of this condition is made through clinical examination associated with radiographs and, if necessary, computed tomography in the search for a better elucidation of the case. Currently, there are several treatment modalities for sialolites, which will depend on their location and dimensions, ranging from conservative treatment with hydration and sialogogs to the surgical removal of sialolite. Case report: This scientific article aims to report the clinical case of a rare sialolite of approximately 37mm, located in the Wharton duct in a geriatric patient. The case was conducted by surgical removal of the sialolite with the creation of a new outlet for the duct. Final considerations: After 2 years of proservation, the buccal floor region shows signs of normality with respect to salivary flow and adjacent anatomical structures and not presenting recurrence of the lesion...

Classification of Sialolithiasis by Location of Stones: Retrospective Review of 534 Cases / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: To investigate epidemiological features of patients with sialolithiasis and to evaluate the difference in outcomes depending on its location. SUBJECTS AND METHOD: We included in the test 472 patients, or 534 cases, who were admitted to the Hallym University Sacred Heart Hospital between February 2006 and May 2017 with the diagnosis of sialolithiasis. The diagnosis of sialolithiasis was established by CT images; all of the cases were classified by the location of stones (orifice to stone/orifice to hilum: 0–0.25, type I; 0.25–0.5, type II; 0.5–0.75, type III; 0.75–1, type IV). RESULTS: The average size of stone was 7.2±4.8 mm and the mean patient age was 36.1±17.4 years old. According to the method described above, 534 cases were classified into the following: type I consisted of 188 cases (35.2%), type II consisted of 55 cases (10.2%), type III consisted of 92 cases (17.2%) and type IV consisted of 199 (37.2%). When comparing these types, stones in Type I were significantly smaller than other groups. There was a significant difference in the surgical method depending on the location of stones. Different complications such as swelling, bleeding, tongue discomfort, ranula, recurrence, etc. have been reported and, together, they statistically show meaningful differences in the distribution depending on types. CONCLUSION: The position of stone in Wharton's duct is important factor that can determine the method of surgical procedure or postoperative prognosis. We recommend 4 types classification of sialolithiasis and it can provide more specific diagnosis of disease and facilitate approach for treatment.

Diagnóstico e tratamento de Sialolitíase: relato de caso / Diagnosis and treatment of Sialolithiasis: Case Report

Sialolitos são estruturas calcificadas, que se desenvolvem no interior do sistema ductal salivar, em decorrência da deposição de sais de cálcio ao redor de um acúmulo de restos orgânicos no lúmen do ducto glandular. Acometem, com mais assiduidade, a glândula submandibular e são a causa mais comum de inflamações agudas ou crônicas nas glândulas salivares maiores. Manifestam-se, com maior frequência, em indivíduos adultos de meia-idade, e os sinais e sintomas mais comuns são a dor e a tumefação local. Podem ser evidenciados por radiografias convencionais, tomografia computadorizada, ressonância magnética, ultrassonografia, cintilografia, sialoendoscopia e sialografia. O tratamento inclui a eliminação espontânea mediante orientações ou uso de medicamentos, ou a remoção cirúrgica do sialolito, sendo necessária, em alguns casos, a exérese da própria glândula. Este trabalho tem como objetivo relatar o caso clínico do paciente S.L.M, 44 anos de idade, sexo feminino, caucasiana, atendida na clínica de Cirurgia Bucal da Universidade Federal Fluminense, apresentando um sialolito no sistema ductal da glândula submandibular do lado esquerdo.

Sialolites are calcified structures that develop inside the salivary ductal system, due to the deposition of calcium salts around an accumulation of organic remains in the lumen of the glandular duct. They have a more frequent involvement of the submandibular gland and are the most common cause of acute or chronic inflammation in the major salivary glands. They occur more frequently in middle-aged adult patients and the most common signs and symptoms are local pain and swelling. They can be evidenced by conventional radiography, computed tomography, MRI, ultrasonography, scintigraphy, sialoendoscopy and sialography. Treatment includes spontaneous elimination, from guidelines or use of medications, or surgical removal of sialolite, in some cases, the excision of the gland itself. This study aims to report the clinical case of the patient S.L.M, 44 years old, female, Caucasian, attended at the Oral Surgery Clinic of the Federal Fluminense University, presenting a sialolite in the ductal system of the left submandibular gland. The patient was submitted to surgical removal of the sialolite, under local anesthesia, without major intercurrences... (AU)

Patología calcificante de las glándulas salivales: presentación de dos casos clínicos / Pathological calcification of the salivary glands: presentation of two clinical cases

La calcificación extraesquelética es una entidad patológica de depósito de sales minerales fuera de las estructuras óseas. Los casos frecuentes se presentan por obstrucción mecánica de la glándula salival o de su conducto excretor, asociada con la formación de sialolitos en el parénquima, su verdadera causa no se conoce con exactitud, pero hay distintas hipótesis con respecto a factores locales y sistémicos. La sialolitiasis es la afección más común de las glándulas salivales en adultos jóvenes, 12 de cada 1,000 pacientes sufren de esta patología, con un predominio del sexo masculino. El diagnóstico se puede establecer mediante ecografía, radiografías oclusales, panorámicas o tomografía cone beam. Estudiamos dos casos de calcificaciones de los tejidos glandulares. El primero de una formación mineral dentro de su conducto y el segundo de una calcificación completa del conducto salival (AU)

Extra bone calcification is a pathological entity of deposit of mineral salts outside bone structures. Frequent cases are due to mechanical obstruction of the salivary gland or its excretory duct, associated with the formation of sialoliths in the parenchyma, its true cause is unknown, but there are different hypotheses regarding the influence local and systemic factors. Sialolithiasis is the most common condition of the salivary glands in young adults, 12 out of 1,000 patients suffer from this pathology, with a predominance of males. Diagnosis can be established by ultrasound, occlusal radiographs, panoramic or cone beam tomography. We studied two cases of calcification of glandular tissues. The first is a mineral formation inside the duct and the second is a complete calcification of the salivary duct (AU)

Sialolito em parênquima de glândula submandibular: relato de caso / Sialolite in parenchyma of submandibular gland: case report

Representando cerca de metade das patologias das glândulas salivares a sialolitíase é uma patologia não neoplásica, inflamatória, caracterizando-se por formação de cálculos no parênquima da glândula salivar ou nos ductos, obstruindo a passagem da saliva. É observada uma maior prevalência de acometimento nas glândulas submandibulares e em homens com idade acima de 40 anos. Considerada multifatorial, possui etiologia desconhecida. Apresenta-se assintomática em cálculos de tamanho reduzido, porém em grandes proporções surgem com sinais e sintomas. Radiograficamente é observado imagem radiopaca em região referente à glândula afetada. Esse trabalho tem como objetivo relatar um caso clínico de um sialolito associado a parênquima da glândula submandibular. Devido às proporções do sialolito associado à queixa da paciente o tratamento cirúrgico foi a melhor opção, alcançando sucesso no pós-operatório(AU)

Representing about half of the pathologies of the salivary glands sialolithiasis is a non-neoplastic, inflammatory pathology, characterized by the formation of calculi in the parenchyma of the salivary gland or ducts, obstructing the passage of saliva. A higher prevalence of involvement in submandibular glands and in men over 40 years old is observed. Considered multifactorial, it has unknown etiology. It is asymptomatic in calculations of reduced size, but in great proportions they appear with signs and symptoms. Radiographically, a radiopaque image is observed in a region related to the affected gland. This paper aims to report a clinical case of a sialolite associated with the submandibular gland parenchyma. Due to the proportions of the sialolito associated to the complaint of the patient the surgical treatment was the best option, reaching postoperative success(AU)

Sialolitíase em equino: relato de caso / Sialolithiasis in equine: case report

Sialolitíase é uma afecção que afeta as glândulas salivares ou seus ductos, caracterizada pela presença de estruturas calcificadas, denominadas de sialolitos, com crescimento lento e gradual, geralmente assintomático, dificultando ou impedindo o fluxo normal de saliva. Devido à ausência de relatos na literatura nacional, descreve-se o caso de uma égua de 15 anos, que apresentava um sialolito de 13cm no ducto parotídico havia mais de dois anos, próximo à crista facial. O diagnóstico foi realizado por meio do exame clínico: visualização do aumento de volume, palpação do sialolito, avaliação odontológica; e de exames complementares: radiografia e ultrassonografia. Optou-se pelo tratamento cirúrgico, através do acesso percutâneo, pois é o mais indicado para cálculos grandes, realizando-se sutura do ducto de Stenon, sem presença de fístulas no pós-operatório. Foi de extrema importância a avaliação e os cuidados odontológicos durante a realização do procedimento, pois as pontas dentárias facilitam a formação dos cálculos.(AU)

Sialolithiasis is a condition that affects the salivary glands or their ducts, characterized by the presence of calcified structures, called sialolites, with slow and gradual growth, usually asymptomatic, hindering or impeding the normal flow of saliva. Due to the absence of reports in the national literature, the case of a 15-year-old mare who had a 13cm sialolite in the parotid duct near the face ridge for more than 2 years is described. The diagnosis was made through clinical examination: with visualization and palpation of the sialolite, dental evaluation; and complementary exams: radiography and ultrasonography. We chose surgical treatment through percutaneous access, which is the most appropriate for large stones, and Stenon's duct suture was performed, without postoperative fistulas. The assessment and dental care during the procedure was extremely important, since the dental tips facilitate the formation of the stones.(AU)

Sialolitíase em glândula salivar menor: relato de caso e revisão de literatura / Sialolithiasis in minor salivary gland: case report and literature review

A sialolitíase é uma afecção que se caracteriza pela obstrução da glândula salivar ou de seu ducto devido à formação de estruturas calcificadas acometendo predominantemente as glândulas submandibulares e muito raramente as glândulas salivares menores. O objetivo deste trabalho é realizar um relato de caso sobre sialolitíase em glândula salivar menor. Paciente do sexo masculino, leucoderma, 54 anos, se apresentou com queixa principal de "tumor na boca". O exame físico intrabucal revelou um nódulo localizado na mucosa labial do lado superior direito, próximo a comissura, único, medindo aproximadamente 2 centímetros no seu maior diâmetro. A ultrassonografia da região do lábio superior evidenciou a hipótese diagnóstica de corpo estranho. O diagnóstico diferencial e o clínico incluíram reação a corpo estranho. Foi realizada a biópsia excisional e durante o ato cirúrgico, foi encontrado um material endurecido, de aproximadamente 3 mm, de cor amarelada, que foi enviado para análise histopatológica, a qual revelou fragmento mineralizado compatível com sialolito. Com base nos achados clínicos e imaginológicos o diagnóstico foi de sialolitíase. Após três meses de acompanhamento, o paciente se apresentou sem evidência da doença. Esta revisão de literatura e o presente relato permitiram concluir que um exame clínico criterioso associado a exames imaginológicos adequados são essenciais para a obtenção de um diagnóstico clínico correto(AU)

Sialolithiasis is a condition characterized by obstruction of salivary gland or its duct due to formation of calcified structure, predominantly affecting the submandibular glands or, rarely, the minor salivary glands. The main objective is to report a case of sialolithiasis in the minor salivary gland on a male patient, leucoderma,54, and his main complaint was a "tumor in the mouth". Intraoral physical examination revealed a nodule located on labial mucosa of the upper right side of the mouth, near the commissure, single, and its diameter measuring approximately 2 cm. The ultrasound examination on the upper lip region resulted in a strange body. The differencial and clinical diagnosis was included strange body. During the excision biopsy surgery, a hardened material, measuring about 3 mm and yellowish was removed and sent for histopathologic exams and the diagnosis was sialolithiasis. After three mouths' follow-up, the patient was free of the disease. This literature review and the present case concluded that a careful clinical examination associated with imaging and histopathology examinations are essential for obtaining a correct clinical diagnosis(AU)
