Diagnosis and treatment of pediatric cervical bronchogenic cyst / 临床耳鼻咽喉头颈外科杂志

Objective:To investigate the clinical characteristics and surgical treatment outcomes of children with cervical bronchogenic cysts. Methods:A retrospective study of 6 pediatric patients with bronchogenic cysts in the neck region treated in our hospital during 2014 to 2020 was performed. All children underwent complete resection of cervical mass under general anesthesia. Results:There were 6 children, aged from 1 to 5 years, with a median of 2.25 years. There were 3 males and 3 females. The lesions were located on the left neck in 3 cases, the midline neck in 2 cases and the right neck in 1 case. The clinical manifestations were painless mass in 5 cases and recurrent neck infection in 1 case. The size of the mass ranged from 2.1 to 7.5 cm. There was no characteristic clinical or imaging features of bronchogenic cysts. Misdiagnosed as lymphangioma in 3 cases, thyroglossal cyst in 2 cases and piriform fistula in 1 case. The follow-up ranged from 1.50 to 7.75 years, with a median of 4.13 years. All 6 children had no recurrence or complications. Conclusion:Although rare, bronchogenic cysts should be considered in the differential diagnosis of cervical cystic masses in children. Surgery is the most effective way to treat cervical bronchogenic cyst, and histopathological examination is the gold standard for diagnosis.

Prevalence of metabolic components in university students / Prevalência de componentes metabólicos em universitários / Prevalencia de componentes metabólicos en universitarios

OBJECTIVE: to identify the frequency of components of Metabolic Syndrome (MetS) among university students. METHOD: descriptive study with 550 students, from various courses run by a public university. The socioeconomic data, lifestyle, and components of MetS were filled out using a questionnaire. Blood sample collection was undertaken in the university itself by a contracted clinical analysis laboratory. RESULTS: 66.2% were female, with a mean age of 22.6±4.41; 71.7% were sedentary; 1.8% stated that they smoke; and 48.5% were classified as at medium risk for alcoholism. 5.8% had raised abdominal circumference and 20.4% had excess weight; 1.3% and 18.9% had raised fasting blood glucose levels and triglycerides, respectively; 64.5% had low HDL cholesterol and 8.7% had blood pressure levels compatible with borderline high blood pressure. Thus, of the sample, 64.4% had at least one component for MetS; 11.6% had two, and 3.5% had three or more. CONCLUSION: a significant proportion of the population already has the components for metabolic syndrome, and this profile reinforces the importance of early diagnosis so as to reduce the risk of developing chronic comorbidities. .

Quiste broncogénico de localización poco habitual: reporte de 2 casos y revisión de la literatura / Bronchogenic cyst of unusual location: report of two cases and review of the literature

El quiste broncogénico es un remanente del desarrollo de traquea y bronquios. Alteraciones en la migración de células durante el desarrollo, permite que estos grupos originen quistes revestidos por epitelio respiratorio. La ubicación más habitual es la intratoráxica, dentro de ella, la intrapulmonar es la más frecuente, seguida de la mediastínica. El diagnóstico definitivo se establece mediante la biopsia diferida. Es una patología poco frecuente y las presentaciones extra torácicas son muy infrecuentes, por lo que compartimos dos casos, uno de ubicación sublingual y otro de ubicación subcutánea en zona escapular.

The bronchogenic cyst is a remanent of the development of the tracheobronchial tree. Alterations in cell migration during development cause the formation of cyst lining by respiratory epithelium. They are usually located in the thorax in lung and mediastinum. The definite diagnosis is realized with the pathology report. This is an uncommon pathological condition and the extra- thoracic forms are very unusual. We present two cases, one of which is of sublingual location and the other of subcutaneous location at the scapular site.

The First Korean Case of Cutaneous Lung Tissue Heterotopia

Cutaneous lung tissue heterotopia is a very rare disorder where mature lung tissues develop in the skin. This is only the second known report of cutaneous lung tissue heterotopia, with the first by Singer et al. in 1998. A newborn infant had a hemangioma-like, freely movable mass connected to the anterior aspect of the sternal manubrium. Pathologic findings showed mature lung tissues with bronchi, bronchioles, and alveoli through the dermis and subcutis, and it was diagnosed as cutaneous lung tissue heterotopia. Cutaneous lung tissue heterotopia is hypervascular, so grossly it looks like a hemangioma. It can be differentiated from pulmonary sequestration, teratoma, bronchogenic cyst, and branchial cleft cyst by histology and the location of the mass. We describe the clinical, radiologic, and pathologic findings of a cutaneous lung tissue heterotopia, the first reported in Korea.

Obesidad mórbida asociada a quiste broncogénico y leiomioma subcardial que simula GIST: caso clínico / Morbid obesity, esophageal bronchogenic cyst and subcardial leiomioma: report of one case

Gastric wall diseases are found in approximately of 1 percent of the patients submitted to bariatric surgery. Half of these are leiomiomas. Esophageal bronchogenic cysts are exceptional We report a 57 years old female with morbid obesity, a bronchogenic esophageal cyst and subcardial leiomioma. The preoperative study and intraoperative biopsy, suggested the presence of a gastrointestinal stromal tumor (GIST), but the definitive pathological study did not confirm its presence. A total gastrectomy was performed, with an uneventful postoperative course.

La patología intramural gástrica tiene una frecuencia menor al 1 por ciento, en cirugía gástrica. Alrededor del 50 por ciento corresponden a leiomiomas. Los quistes broncogénicos tienen origen embriológico y son excepcionales, y la mayor parte de los reportes corresponden a pacientes pediátricos. Se presenta un caso clínico de paciente portadora de Obesidad mórbida (IMC = 52), asociado a lesión subcardial que simula GIST, cuyo estudio histopatológico resultó ser un quiste esofágico de origen broncogénico de 40 mm, asociado a leiomioma subcardial de 10 mm. Fue sometida a gastrectomía total más anastomosis esófago-yeyunal en Y de Roux, con asa de 180 cm. No presentó morbi-mortalidad postoperatoria. Se discuten los métodos de estudio preoperatorio y las alternativas terapéuticas. No hemos encontrado en la literatura otro caso de asociación de estas raras patologías.

Sternal bronchogenic cyst: a rare condition

Bronchogenic cyst is a congenital developmental abnormality of the embryonic foregut usually formed as a result of an accessory lung bud becoming isolated from the rest of the tracheobroncheal tree. Usually a solitary extra pulmonary cyst, it's a benign condition, found most commonly in the mediastinum with rare occurrence on the skin or subcutaneous tissues.We report a case of cutaneous bronchogenic cyst that occurred in the skin over the manubrium sterni of four years old boy. The diagnosis was made by the histopathological findings which revealed ciliated and mucin-producing pseudo stratified columnar epithelium of respiratory type

Isolated oesophageal cyst connected with the bronchus

We report an unusual case of a patient with an oesophageal cyst connected to the bronchus. A 24-year old male with a two-year history of repeated attacks of chest infection and haemoptysis was found to have a cyst of 4 x 4 cm affecting the anterior and apical segments of the right upper lobe. The cyst was excised in its entirety and the histopathological study of the cyst showed stratified squamous epithelium with submucosal and muscular layer but no cartilage. The pathological diagnosis was an oesophageal cyst. No previous case of isolated oesophageal cyst connected to the bronchus has been reported according to the available literature.

Quiste broncogénico retroperitoneal: Caso clínico / Retroperitoneal bronchogenic cyst: Report of one case

Retroperitoneal cystic tumors are uncommon. More than two thirds are malignant. Benign lesions include lipomas and íeiomyomas, among others. Bronchogenic cysts are congenital anomalies that result from an abnormal budding of the primitive foregut, and are most commonly found in the mediastinum. Occasionally they can be seen in the skin, subcutaneous tissue, in the pre-sternal andpericardial areas, but those located under the diaphragm are extremely rare. We report a 24 year-old female who consulted for abdominal pain. An abdominal ultrasound disclosed a retroperitoneal cystic lesion, that was confirmed with a CAT scan. The patient was operated, finding a cyst that was adhered to the pancreas. A distal pancreatectomy and cyst excision were done. The pathological examination of the lesion showed a bronchogenic cyst. The patient was discharged ten days after surgery.

Quiste broncogénico de la pared torácica: caso clínico y revisión de la literatura / Bronchogenic cyst in the chest wall

Los quistes broncogénicos se ubican en la mayoría de los casos en la cavidad torácica, en relación con el árbol bronquial, en la periferia del parénquima pulmonar o en el mediastino. Sin embargo, existen casos infrecuentes en que el quiste se localiza en la pared torácica, principalmente en el tejido celular subcutáneo presternal, en la región cervical y el abdomen. Se postula que la ubicación fuera de la cavidad torácica ocurre por migración, o pinzamiento del tejido pulmonar normal durante la fusión de los procesos esternales o diafragmáticos. En este artículo, se presenta como caso clínico, un paciente de 10 años de edad, de sexo masculino, que presentó una lesión nodular presternal, confirmada como quiste broncogenético en el estudio histológico. Se revisa la literatura al respecto y se discute el enfoque diagnóstico y terapéutico más adecuado a esta patología.

Periscapular bronchogenic cyst.

Periscapular location of bronchogenic cysts is extremely rare with four cases reported in literature. We report a relatively late presentation in a ten-year-old boy that was clinically mistaken for a typical sebaceous cyst. The definitive treatment is total excision after preoperative imaging to detect the occasional intrathoracic extension. Histologically they are lined by pseudostratified ciliated columnar epithelium, which can rarely undergo malignant transformation.

Quiste broncogénico cutáneo: presentación de un caso / Cutaneous bronchogenic cyst: a case report

Los quistes broncogénicos son malformaciones desarrolladas a partir de estructuras del árbol tráqueo-bronquial. Se localizan habitualmente en pulmones o mediastino y excepcionalmente a nivel cutáneo. Presentamos un caso de quiste ciliado cutáneo de localización pre-esternal en un niño de 8 años de edad. El estudio histopatológico de la pieza quirúrgica reveló una formación quística revestida por epitelio cilíndrico ciliado pseudoestratificado, que incluye células mucosas. Se halla rodeado por tejido conectivo que incluye fascículos de músculo liso. Constituye el caso N§ 55 de las publicaciones internacionales consultadas y el tercero reportado en nuestro medio

Quiste broncogénico en el tejido celular subcutáneo / Bronchogenic cyst in the subcutaneous tissue

Se presenta un caso de tumor ubicado en el tejido celular subcutáneo de la pared anterior al tórax, a nivel del manubrio esternal, con diagnóstico clínico preoperatorio de lipoma y diagnóstico ecográfico de tumor quístico. El plan quirúrgico consistió en extirpación total del tumor, incluida su cápsula. Durante el acto quirúrgico se constató una masa tumoral de 9 cm de diámetro y de consistencia dura. La extirpación determinó la extensión hasta la aponeurosis del musculus pectoralis major, produciendo una impronta en el mismo. La apertura del tumor demostró el contenido líquido con características viscosas y de color amarillento. El diagnóstico histológico confirmó la presencia de tejidos de células cilíndricas, ciliadas, mucosecretantes, confiriéndole el diagnóstico de quiste broncogénico en tejido subcutáneo. Debido a la rareza del caso se efectuó búsqueda bibliográfica a fin de actualizar el tema, encontrando 49 casos publicados en la literatura mundial, sin mención alguna en Iberolatinoamérica

Quiste broncogénico cervical anterior, simulando lesión tiroidea: caso clínico / Anterior cervical bronchogenic cyst simulating a thyroid lesion: clinical case

Bronchogenic cysts are congenital malformations of the tracheo-bronchial tree usually located intrathoraxically. We report a 44 years old male with a bronchogenic cyst located exceptionally in the pre tracheal anterior cervical region, simulating a thyroid lesion

Retroperitoneal multilocular bronchogenic cyst adjacent to adrenal gland

Bronchogenic cysts are generally found in the mediastinum, particularly posterior to the carina, but they rarely occur in such unusual sites as the skin, subcutaneous tissue, pericardium, and even the retroperitoneum. A 30-year-old Korean man underwent surgery to remove a cystic adrenal mass incidentally discovered during routine physical checkup. At surgery, it proved to be a multilocular cyst located in the retroperitoneum adjacent to the left adrenal gland. Microscopically, the cyst was lined by respiratory epithelium over connective tissue with submucous glands, cartilage and smooth muscle, thereby histologically confirming bronchogenic cyst. This is the first reported case of retroperitoneal bronchogenic cyst in an adult without other congenital anomalies in Korea.

Quiste broncogénico en el adulto: tratamiento quirúrgico / Bronchogenic cyst in adults: surgical treatment

Se informan los hallazgos radiográficos e histopatológicos encontrados en cinco pacientes que fueron hospitalizados y operados en el Complejo Hospitalario de la Caja de Seguro Social, con diagnóstico de quiste broncogénico. Ninguno de ellos tenía síntomas ni signos de infección pulmonar. El postoperatorio inmediato y tardío fue bueno, en todos los casos. El quiste broncogénico estaba localizado en el parénquima pulmonar de los dos casos que tenían imagen hidroaérea
