RESUMO

Resumen La adenopatía dermatopática es una entidad histopatológica que consiste en un aumento del tamaño ganglionar en respuesta a enfermedades cutáneas crónicas. En el análisis histopatológico se observa una hiperplasia paracortical con presencia de células dendríticas, células de Langerhans e histiocitos. La presentación clínica más habitual es la aparición de adenopatías de características benignas con o sin prurito en pacientes con antecedentes de enfermedad cutánea. La aparición de masas laterocervicales es un motivo de consulta frecuente en otorrinolaringología. Presentamos el caso de un paciente exfumador de 41 años que consultó por aparición brusca de una masa cervical quística, sugestiva de quiste braquial o de una adenopatía quística. Una vez descartada malignidad, se procedió a realizar exéresis de la lesión mediante cervicotomía para diagnóstico patológico. El estudio de la muestra confirmó el diagnóstico de adenopatía dermatopática en un paciente sin antecedente de enfermedad cutánea previa.

Abstract Dermatopathic lymphadenopathy is a histopathologic entity which consists on reactive lymphadenopathy in the setting of chronic cutaneous diseases. The histologic examination is characterized by paracortical hyperplasia with presence of dendritic cells, Langerhans cells and histiocytes. The most common clinical presentation is the presence of lymphadenopathy with benign characteristics with or without pruritus in patients with prior history of cutaneous disease. The appearance of laterocervical masses is a frequent reason for consultation in otorhinolaryngology. We present the case of a 41-year-old ex-smoker who consulted due to the sudden appearance of a cystic cervical mass, suggestive of a brachial cyst or cystic adenopathy. Once malignancy had been ruled out, excision of the lesion within cervicotomy was performed in order to reach a pathological diagnosis. The histologic study confirmed the diagnosis of dermatopathic adenopathy in a patient with no history of previous skin disease.

RESUMO

Branchial cleft cysts (BCCs) are common causes of cervical tumors in children and adulthood; however, prenatal diagnosis of BCC is rare. In neonates, these cysts can suddenly increase in size, causing airway obstruction and becoming a life-threatening condition. In this case report, we describe the prenatal diagnosis of a third BCC at the 25th week of pregnancy using ultrasound, magnetic resonance imaging, and three-dimensional virtual models, as well as the perinatal outcomes of this rare condition.

RESUMO

PURPOSE: We aimed to compare the histomorphological features of oral lymphoepithelial cysts (OLC) in different locations of the oral cavity and to verify the association between oral lymphoepithelial cysts and subgemmal neurogenous plaque (SNP) on biopsies from the lateral border of the tongue. METHODS: All cases diagnosed as OLC from the Oral Pathology Service at the School of Dentistry/University of São Paulo were retrieved. For all the cysts located in the tongue, their association to SNP was analyzed. Immunohistochemical staining against S100 was performed to confirm the diagnosis of SNP. RESULTS: Thirty-one cases were selected for morphological analysis and SNP was identified in 40% of cases, all of them positive for S100. In these cases, macroscopic analysis demonstrated two independent fragments. Microscopic analysis showed that cysts located in the floor of the mouth and ventral surface of the tongue showed less intense exocytosis, less formation of lymphoid follicles, and predominantly a moderate inflammatory infiltrate. CONCLUSIONS: OLC have a similar histological pattern regardless the location within the oral cavity and. In some cases, the biopsy specimen may be accompanied by a SNP as an adjacent independent structure.

RESUMO

Dentro de los quistes cervicales congénitos los quistes branquiales son los segundos en frecuencia luego del quiste tirogloso, representando el 24% de los casos. De éstos, los quistes de segundo arco branquial son los más frecuentes con 90%-95% de los casos. Se presentan en un amplio rango de edad siendo comúnmente diagnosticados en niños mayores y adultos, cuya primera manifestación clínica puede ser un aumento de volumen relativamente brusco por infección. Se presenta el caso clínico de un recién nacido (RN) que debuta a las 48 horas de vida con estridor y dificultad para la alimentación oral. El estudio de imágenes con tomografía computarizada (TC) y resonancia magnética (RM) muestran una lesión quística del espacio parafaríngeo derecho que se proyecta hacia nasofaringe y orofaringe. Se realiza la exéresis de la lesión vía transoral. Biopsia rápida y diferida confirman diagnóstico de quiste branquial. Se revisa literatura sobre quistes de segundo arco branquial de ubicación en el espacio parafaríngeo siendo muy pocos los casos reportados.

Within the congenital cervical necks, the branchial cleft cyst are the second in the frequency after the shooting, accounting for 24% of the cases. Of the Second branchial cleft cyst are with the most frequent with 90-95% of the cases. It occurs in a wide range of ages and is commonly diagnosed in older children and adults, whose first clinical manifestation may be an increase in volume after infection. We present a clinical case of newborn that debuts at 48 hours of life with stridor and difficulty for oral feeding. The imaging study with Computed Tomography (CT) and Magnetic Resonance imaging (MRI) show a cystic lesion of the right parapharyngeal space projecting into the nasopharynx and oropharynx. The excision of the transoral lesion is performed. Frozen biopsy and diagnostic biopsy demonstrating a branchial cyst. We review the literature on the second branchial cleft cyst of the location in the parapharyngeal space with very few reported cases.

RESUMO

La malformaciones de arcos branquiales constituyen la segunda causa de masa congénita de cabeza y cuello en niños. La presentación clínica depende del arco afectado, siendo las más frecuentes las de segundo arco branquial. Se presenta un caso clínico de un escolar de 7 años que consulta por disfagia lógica, evidenciándose una gran masa orofaríngea posterior a pilar faríngeo posterior izquierdo. El estudio de imágenes con tomografía computarizada (TC) y resonancia magnética (RM) de cuello mostró una lesión quística en relación al pilar faríngeo posterior izquierdo. Se realizó resección transoral de la lesión conservando su pared lateral. El estudio anatomopatológico resultó sugerente de quiste de segundo arco branquial. Se discute la presentación clínica, diagnóstico y alternativas de tratamiento de las anomalías de segundo arco branquial.

Branquial cleft malformations are the second cause of congenital mass of the head and neck in children. The clinical presentation depends on the cleft involved; second branchial cleft anomalies are the most common. There is a case of a 7 years old boy with a history of logic dysphagia, fisical examination shows a large oropharyngeal mass located behind the left posterior pillar of the pharynx. The imaging study with computed tomography (CT) and magnetic resonance imaging (MRI) of the neck showed a cystic lesion in relation to the left posterior pillar of the pharynx. Transoral resection of the lesion was performed keeping its lateral wall. Pathologic examination was suggestive of second branchial cyst. Clinical presentation, diagnosis and treatment options of the second branchial cleft anomalies are discussed.

RESUMO

Branchial Cysts are uncommon anomalies in regular clinical practice. However, among congenital cervical cysts, they represent about 30% from total. Objective: Characterize patients diagnosed with operated branquial cyst in our clinical center, and correlate clinic, imaging and final diagnose. Material and methods: Retrospective descriptive study of discharged patients diagnosed as cervical cysts, between January 2005 and July 2011, at Hospital Clinico Universidad de Chile. Selection of Clinical records with final diagnose of branchial cyst were selected. Age, sex, clinical story, imaging exams, pre-operative and post-operative diagnoses, and biopsy report were registered. Results: from a total of 149 cervical cysts, 31 (20,8%) were branchial cysts. Man 45% and women 55%. By age, 9 (29%) were < 15 years old (average: 6,69 years) and 22 (70,9%) > 15 years (average: 33,7 years). Lateral cervical mass was the most common clinical manifestation. Regarding Imaging study, 15 cervical ultrasounds (sensibility 0,86 and specificity 0,98) and 13 cervical CTA scans (sensibility 0,92 and specificity 0,94) were conducted. In 9 patients, imaging studies weren't conducted for the clinical diagnose (sensibility 0,77 and specificity 0,98). Correlation of pre-operative and post-operative diagnose was 87%. Discussion: According to literature, presentation age is generally during childhood; however, in our statistics it presented during adult age, which could be explained due to the main focus our medical center has for adult population. Most common clinical presentation was lateral neck mass, which had a good clinical correlation, however improves with imaging studies. (AU)

RESUMO

El quiste branquial de origen congénito que aparece en la región lateral del cuello es, con frecuencia, motivo de consulta. Se tuvo como objetivo determinar el comportamiento de los quistes branquiales en el Hospital Ciro Redondo García, de Artemisa en el periodo de 1993 al 2009. Se realizó un estudio descriptivo transversal de los quistes branquiales diagnosticados en pacientes intervenidos quirúrgicamente en el Servicio de Cirugía Maxilofacial. Se estudiaron la edad, el sexo, el color de la piel, el lado del cuello afectado, el resultado histopatológico y los medios auxiliares empleados. Se encontraron 12 quistes branquiales que afectaron el 50 por ciento de ambos sexos, un 75 por ciento a pacientes entre 15 y 30 años y un 75 por ciento de la piel blanca, un 66,7 por ciento afectó el lado derecho del cuello y en un 100 por ciento de los casos se utilizó la biopsia y el ultrasonido como medios auxiliares para su diagnóstico. Se encontró epitelio escamoso estratificado en un 100 por ciento de los quistes y en un 91,6 por ciento el tejido linfoide. No se encontró predilección por el sexo, la mayoría de los pacientes eran menores de 30 años, de piel blanca y presentaban los quistes en el lado derecho del cuello. En todos los pacientes se empleó la biopsia y el ultrasonido como medios auxiliares de diagnóstico. El epitelio escamoso estratificado y el tejido linfoide fueron los hallazgos histopatológicos más relevantes(AU)

The congenital branchial cyst appearaing in the lateral region of the neck is frequently consultation reason. The aim was to determine the behavior of the branchial cysts in the patients admitted in the Ciro Redondo García General Teaching Hospital of Artemisa municipality from 1993 to 2009. A cross-sectional and descriptive study was conducted of the branchial cysts diagnosed in patients operated on in the Maxillofacial Surgery Service. Study variables were: age, sex, the skin color, neck involved side, histopathological result and the auxiliary means used. There appear 12 branchial cysts involving the 50 per cent of both sexes, a 75 per cent aged between 15 and 30 and a 75 per cent of white skin, a 66,7 per cent involved the neck right side and in a 100 per cent of cases authors used biopsy and ultrasound as auxiliary means for its diagnosis. There was a stratified squamous epithelium in a 100 per cent of cysts and in a 91,6 per cent the lymphoid tissue. There was not predominance of sex, most of patient were aged under 30, white skin and had cysts in the neck right side. In all patients authors used the biopsy and ultrasound as diagnostic auxiliary means. The stratified squamous epithelium and the lymphoid tissue were the more relevant histopathological findings(AU)
