Rasgos clínicos e histopatológicos de quistes de retención salival

RESUMEN Introducción: La formación de los quistes de retención salival denominados mucocele y ránula se encuentran entre las afecciones de las glándulas salivales más frecuentes en edades pediátricas. Objetivo: Examinar los rasgos clínico e histopatológico de los quistes de retención salival. Métodos: Estudio descriptivo retroprospectivo de corte trasversal de octubre de 2017 a septiembre de 2019 en 43 pacientes atendidos por consulta externa de maxilofacial del Hospital Pediátrico Universitario "William Soler Ledea" con confirmación histopatológica de quistes de retención salival. Las variables a medir fueron: edad, sexo, etiología, rasgos clínicos, localización y aspecto histopatológico. Resultados: El mucocele fue el diagnóstico en 83 % de los casos y las diferencias por sexo fueron significativas con afectación mayor para el sexo femenino, la etiología más frecuente fue el mordisqueo del labio con 48,8 %, la localización más frecuente el labio inferior con 72,0 %. Hubo relación significativa entre la etiología y las características histopatológicas. Conclusiones: El quiste de retención salival más frecuente es el mucocele con predominio en el sexo femenino, de aspecto nodular, tamaño menor de 5 mm; predominó la localización en el labio inferior y de causa por mordisqueo del labio. Histopatológicamente la ausencia de revestimiento epitelial y presencia de inflamatorio agudo es lo más frecuente.

ABSTRACT Introduction: The formation of salivary retention cysts called mucocele and granula are among the most frequent conditions of the salivary glands in pediatric ages. Objective: Assess the clinical and histopathological features of salivary retention cysts. Methods: A retroprospective, descriptive and cross-sectional study was carried out from October 2017 to September 2019 in 43 patients with histopathological confirmation of salivary retention cysts attended by the maxillofacial outpatient clinic of "William Soler Ledea" University Pediatric Hospital. The variables to be measured were: age, sex, etiology, clinical features, location and histopathological appearance. Results: Mucocele was the diagnosis in 83.0% of the cases and the differences by sex were significant with greater involvement for the female sex, the most frequent etiology was the bite of the lip with 48.8%, and the most frequent location the lower lip with 72.0%. There was a significant relationship between the etiology and histopathological characteristics. Conclusions: The most frequent salivary retention cyst is the mucocele with predominance in the female sex, of nodular appearance, size less than five mm; there was a predominance of localization in the lower lip and caused by the bite of the lip; histopathologically, the absence of epithelial lining and presence of acute inflammation are the most frequent.

Association between the seasonal changes and mucous retention cyst of maxillary antrum in cone beam computed tomography images in a sample population of Isfahan, Iran

Mucous retention cysts (MRCs) of the maxillary sinuses are incidental findings in radiographs of the oral and maxillofacial structures. These cysts usually appear as rounded, dome-shaped, and soft-tissue masses, most often on the floor of the maxillary sinus. The aim of this study was to determine the prevalence of maxillary antral MRC and the effect of seasonal variation, sex and age in cone beam computed tomography (CBCT) images. Materials and Methods: In this simple, nonrandomized, cross-sectional study, CBCT images of patients were reviewed to evaluate the prevalence of MRCs and its location in the antrum, uni or bilateral, size, and season in which MRC occurred. The findings were analyzed using Statistical software SPSS and t-tests (P > 0.05). Results: A total of 765 CBCT images were evaluated (380 males and 385 females); 180 were suggestive of MRCs, 110 occurred in males (28.9%) while 70 (18.2%) occurred in females, which resulted in a prevalence of 23.5%. The peak prevalence of MRC was found in spring (41.6% of all radiographs), but there was no significant statistical difference between the occurrence of MRCs in different seasons (P > 0.05). Conclusion: This study showed no significant difference between the occurrences of MRCs in different seasons. There was no significant difference between male and female and different decades of life. Furthermore, there was no significant difference between the involvement of right and left maxillary sinuses and different walls of the antrum.

Arteriovenous Malformation with a Retention Cyst of the Pancreas / 대한췌담도학회지

Arteriovenous malformation (AVM) of the pancreas is exceedingly rare, although it may be increasingly diagnosed due to the widespread use of cross-sectional imaging of the abdomen; even rarer is its association with pancreatitis. A 45-year-old male was admitted to our hospital with symptom of epigastric pain. Dynamic contrast imaging scans of the abdomen showed a focal acute pancreatitis and pancreatic AVM. The angiography findings were compatible with pancreatic AVM. The cause of abdominal pain was diagnosed by acute pancreatitis caused by pancreatic AVM, and, for definitive treatment of symptomatic pancreatic AVM, distal pancreatectomy with splenectomy was performed. The histological results confirmed the presence of irregular dilated tortuous arteries and veins, and a retention cyst with epithelial cell lining. We experienced a rare case of a 45-year-old-Korean male who had acute pancreatitis associated with pancreatic AVM. Pancreatic AVM is extremely rare; even rarer is its association with pancreatitis.

Clinical evaluation of sinus bone graft in patients with mucous retention cyst / 대한악안면성형재건외과학회지

BACKGROUND: Mucous retention cyst refers to a cyst made by expansion due to the blockage of the salivary gland near the maxillary sinus, and it is surrounded by epithelial cells. Most of them are small; therefore, they cannot be found well and are frequently with antral polyp. The aim of this study was to evaluate the clinical prognosis of sinus bone graft in patients with mucous retention cyst. METHODS: This study was performed retrospectively on 23 patients who had sinus bone graft. Group 1 was 8 patients (10 sinuses) who had a mucous retention cyst, and group 2 was 15 patients (17 sinuses) who had no pathologic history about the maxillary sinus. For these patients, sinus bone graft was performed using the lateral approach technique. The total 51 implants were placed 6.22 weeks on the average after sinus bone graft. Sinus membrane perforation during operation, postoperative complications, marginal bone loss after restorative function, implant success rate, and survival rate were analyzed. RESULTS: There was no complication in group 1, and there were three complications in group 2. In group 2, two cases of implants failed. The types of postoperative complications consisted of two minor infections and one wound dehiscence. Two implants of total 51 implants were removed, and the survival rate of implants was 96.08 % (group 1 100 %, group 2 93.5 %). The total success rate of implants was 92.2 % (group 1 95 %, group 2 90.3 %). CONCLUSIONS: The clinical prognosis was not affected by the presence of mucous retention cyst.

Herniación de quiste de seno maxilar a través de fístula oroantral: reporte de un caso / Hermiation of a maxillary sinus cyst through an oroantral fistula: report of a case

Los quistes de retención mucosa y los mucoceles son las lesiones máscomunes de los senos paranasales. Éstos comparten características muysimilares y su diferencia estará determinada por su etiología. A diferencia del quiste de retención mucosa, cuyo comportamiento es mucho más sutil, el mucocele causa fenómenos infl amatorios locales, y algunas veces,reabsorción ósea de las estructuras adyacentes. El tratamiento será laenucleación quirúrgica. En el caso clínico que presentamos a continuación,se evidencia una lesión quística que se expone a través del alvéolo no cicatrizal de extracción traumática realizada semanas atrás, además se presenta la técnica que utilizamos para el cierre de fístula oroantral.

Mucus retention cysts and mucoceles are the most common lesions of the paranasal sinuses. They share very similar characteristics and the difference between them depends on their etiology. Unlike mucous reten-tion cysts, whose behavior is much more subtle, mucoceles cause local infl ammatory phenomena and sometimes bone resorption of adjacent structures. The treatment called for is surgical enucleation. The clinical case presented deals with a cystic lesion protruding through the non-cicatricial alveolus following a traumatic extraction performed weeks earlier. We also present the technique used to close the oroantral fi stula.

Presencia de quistes de retención mucoso del seno maxilar detectados por radiografías panorámicas en pacientes de la ciudad de Temuco, Chile / Presence of mucus retention cysts in maxillary sinus detected by panoramic radiographs on patients of Temuco, Chile

Los quistes de retención mucoso son una patología muy poco frecuente en el seno maxilar, pero de fácil detección en radiografías panorámicas. El propósito de este estudio fue cuantificar los casos de mucoceles en senos maxilares durante un periodo de 5 meses, observando su frecuencia por edad y sexo. Se encontró una prevalencia de 2.06 por ciento en 339 radiografías revisadas, observándose mayor frecuencia en el género masculino y a una edad promedio de 30 años. Todos los casos no manifestaron sintomatología alguna.

Mucus retention cyst are a pathology with very low frequency in maxillary sinus, but easy to detect in panoramic radiographs. The aim of this study was quantify mucocele cases in maxillary sinus along five months, detecting their frequency by age and sex. It was found a prevalence of 2.06 percent, noting more frequently in male sex and with an average age of 30. All cases were presented without previous symptomatology.

Magnetic Resonance Imaging of the Sinus : Prevalence and Clinical Significance of Incidental Abnormal Findings in a Common Population

BACKGROUND AND OBJECTIVES: The purpose of this study is to determine the prevalence of abnormalities in the sinuses among the common population, and to correlate this with clinical data. MATERIALS AND METHODS: We retrospectively evaluated a total of five hundred patients who visited the Health Promotion Center, Asan Medical Center, to undergo MRI scan to screen for intracranial pathology from January to April, 2003. Patients who have been treated for nasal or sinus diseases and who had previous history of nasal or sinus operations were excluded. The sinus abnormalities found through the MRI were classified into 2 types as follows; sinusitis group and retention cyst group. RESULTS: Among the five hundred patients studied, ninety-six (19.2%) patients showed abnormality in one or more sinus groups; ninety patients displayed symptoms of sinusitis and nine patients exhibited signs of retention cyst. Three patients showed symptoms of both. Sinus abnormalities were most commonly observed in the maxillary sinus. Seven patients had symptoms of the sinusitis group, and one patient had symptoms of the retention cyst group. CONCLUSION: Incidental sinus abnormalities detected among the common population were relatively common. However, pathologic condition which demanded treatment among these abnormalities were rare. Therefore, it would be important not to overestimate these signs and one should evaluate their clinical correlations carefully through complete physical examinations before applying any treatment for these lesions.

Cysts of the pancreas: a report of two cases

A case of pseudosyst of the pancreas is reported, demonstrating the successful use of marsupialization. Because of the relative rarity of this condition, special attention is called to the ease with which it can be mistaken for other more common causes of encysted fluids, and to the special means for differentiating it.

A Case of Retention Cyst of the Pancreas / 대한소화기내시경학회지

A 38-year-old woman was admitted for evaluation of cyst-like lesion of the pancreas, which was incidentally found on physical check up. She has been well until the lesion was found except epigastric pain. On endoscopic retrograde pancreatogram, pancreatic head portion revealed a 2 x 2 cm sized cystic mass with marginal calcification. There was no definitive communication between pancreatic duct and cyatic mass, but amylase level of cystic content was increased. Surgical excision was performed, Microspically, the cystic wall showed flat lining epithelium with dense fibrosis and dysplastic calcification accompanied by chronic pancreatitis of adjacent pancreatic tissue.
