Caracterización epidemiológica y clínica de pacientes operados con diagnóstico de quiste branquial / Epidemiological and clinical characterization of operated patients diagnosed with branchial cyst

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)

Comportamiento del quiste branquial en pacientes del Hospital General Docente Ciro Redondo García, Artemisa, 1993-2009 / Behavior of branchial cyst in patients admitted in the \"Ciro Redondo García\", General Teaching Hospital, Artemisa municipality, 1993-2009

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)

Quistes de la segunda hendidura branquial: revisión de 32 casos operados / Second branchial cleft cysts: review of 32 operated cases

The aim of this work was to analize retrospectively the clinical features of 32 patients aged 23.9 years (21 female) with histological diagnosis of second branchial cleft cyst. In 28 patients, the cyst was localized below the mandibular angle. The presenting symptom was a cervical tumor in 30 patients and pain in eight. Fourteen aspiration punctures was performed obtaining 8 purulent and 6 straw colored aspirates. The preoperative diagnosis was correctly made in only 19 patients; the principal confounding diagnosis was tuberculous adenitis. All patients were operated performing a complete cystectomy in 30 and partial cystectomy in 2. Three patients had a surgical wound infection and the cyst recurred 5 months and 4 years after operation in the 2 patients subjected to partial cystectomy. The histological study revealed squamous epithelial with underlying lymphoid tissue. It is concluded that aspiration puncture is useful for the correct diagnosis and that the cyst must be completely erradicated to avoid recurrences
