Behavior of squamous cell carcinoma of the floor of the mouth. Is supraomohyoi neck dissection sufficiently safe to manage clinically N0 patients? / Carcinoma epidermoide del suelo de la boca. ¿Es suficientemente seguro el vaciamiento cervical supraomohioideo para tratar clínicamente a los pacientes N0?

Aim: The main aim of the present report is to study the behavior of SCC of the floor of the mouth. Materials and method: A retrospective analysis was conducted using the records of patients diagnosed with squamous cell carcinoma of the floor of the mouth between 2000 and 2012 in the HUVN. Ninety-three patients with squamous cell carcinoma of the floor of the mouth treated with tumourectomy and selective neck dissection were included in the study. The pattern of distribution of cervical metastases and numerous histological features such as T-stage, N stage, surgical margins, tumor thickness, ECS (extracapsular spread) and vascular invasion were analyzed. Results: Level I was the most affected level, followed by Level II. T stage, tumor thickness, and surgical margins showed a strong relationship with the risk of developing a local or cervical failure at follow-up. Overall survival was 52.7%. T stage, tumor thickness, N stage, recurrence, extracapsular spread, and vascular invasion were also associated with a poor prognosis. Conclusions: SCC of the floor of the mouth is an aggressive disease even at early stages. Due to the low rate of positive nodes observed at level IV and V in clinically N0 patients, supraomohyoid neck dissection might be considered sufficiently safe in this group

Objetivo: El principal objetivo de este estudio es estudiar el comportamiento clínico del carcinoma epidermoide del suelo de la boca. Materiales y método: Se realizó un estudio retrospectivo utilizando los registros de pacientes diagnosticados de carcinoma de células escamosas del suelo de la boca entre 2000 y 2012 en el Hospital Universitario Virgen de las Nieves de Granada. En el estudio se incluyeron 93 pacientes con carcinoma epidermoide del suelo de boca tratados con tumorectomía y disección selectiva del cuello. Se analizó el patrón de distribución de las metástasis cervicales y numerosas características histológicas, como el estadio T, el estadio N, los márgenes quirúrgicos, el espesor tumoral, la diseminación extracapsular y la invasión vascular. Resultados: El nivel I fue el más afectado, seguido del nivel II. El estadio T, el espesor tumoral y los márgenes quirúrgicos mostraron una fuerte relación con el riesgo de desarrollar una recidiva local o cervical durante el seguimiento. La supervivencia global fue del 52,7%. El estadio T, el espesor tumoral, el estadio N, la recurrencia, la diseminación extracapsular y la invasión vascular también se asociaron a un mal pronóstico. Conclusión: El carcinoma epidermoide del suelo de la boca representa una enfermedad agresiva incluso en estadios tempranos. Debido a la baja tasa de ganglios positivos observada en los niveles IV y V en pacientes clínicamente N0, la disección supraomohioidea del cuello puede considerarse suficientemente segura en este grupo de pacientes

Endovascular treatment of an intraosseous arteriovenous malformation of the mandible in a child. A case Report.

The modern application of interventional radiology techniques is revolutionizing the treatment of the vascular malformations of the head and neck. In fact, the morbidity related with the surgical extirpation of the malformation might be drastically reduced with the use of an endovascular approach. The present report describes the case of a 11 years old male affected by a large intraosseous arteriovenous malformation of the mandible. The coil embolization of the main drainage vein caused the spontaneous regression of the lesion and avoided a mutilating surgery and severe psychological sequels. A multidisciplinary approach of these case is mandatory. A careful clinical and radiological study of the patient is essential for a proper management. The choice of the treatment should be based on the location and extension of the malformation, age of the patient, experience with endovascular techniques and clinic. Key words:Endovacualr approach, intraosseous arteriovenous malformation, head and neck, child.

Tapia's syndrome: pathogenetic mechanisms, diagnostic management, and proper treatment: a case series.

BACKGROUND: Tapia's syndrome is an uncommon disease described in 1904 by Antonio Garcia Tapia, a Spanish otolaryngologist. It is characterized by concomitant paralysis of the hypoglossal (XIIth) and pneumogastric (Xth) nerves. Only 69 cases have been described in the literature. Typically, the reported patients presented with a history of orotracheal intubation. Common symptoms are dysphonia, tongue deviation toward the affected side, lingual motility disturbance, and swallowing difficulty. CASE PRESENTATION: In the report, we describe three cases of Tapia's syndrome in three Caucasian patients who underwent surgery with general anesthesia. Two of these patients underwent neck abscess drainage, and the third had an open reduction of a shoulder fracture. The clinical symptoms of Tapia's syndrome appeared after extubation. All three of our patients recovered their lost function at 3 months after diagnosis. CONCLUSIONS: We underline the importance of performing airway endoscopy and a specific program of swallowing rehabilitation for the proper management of Tapia's syndrome.

Multiple oral fibropapillomatosis as an initial manifestation of Cowden Syndrome. Case report.

Cowden syndrome is a rare hereditary disease included within hamartoma-type gastrointestinal polyposis. It is characterised by associated mucocutaneous anomalies and by the extraordinary tendency to develop malignant neoplasia, mainly in the breast and thyroid. Early diagnosis of the syndrome and adequate tumoral screening in patients with mucocutaneous papillomatosis make it possible to make an earlier diagnosis of associated pathologies which have great morbidity when detected late. We present the case of a patient diagnosed with Cowden syndrome after consultation for labial papillomatous lesions of long evolution who was subsequently treated for breast and kidney cancer in initial stages. The correct diagnosis of a banal pathology of oral mucosa made it possible for us to take early action against the neoplastic pathology associated with this disease.

Fibropapilomatosis oral múltiple como manifestación inicial de Síndrome de Cowden. Caso clínico / Multiple oral fibropapillomatosis as an initial manifestation of Cowden Syndrome. Case report

El síndrome de Cowden es una infrecuente enfermedad hereditaria englobada dentro de las poliposis gastrointestinales de tipo hamartomatoso. Se caracteriza por asociar anomalías cutaneomucosas y por la extraordinaria tendencia a desarrollar neoplasias malignas, principalmente de mama y tiroides. La importancia de un diagnóstico precoz del síndrome y de un adecuado screening tumoral en pacientes con lesiones papilomatosas cutaneomucosas, nos va a permitir adelantarnos en el diagnóstico de patologías con enorme morbimortalidad asociada en caso de una detección tardía. Presentamos el caso de una paciente diagnosticada de síndrome de Cowden tras consultar por lesiones papilomatosas labiales de largo tiempo de evolución y tratada posteriormente de cáncer de mama y riñón en estadios iniciales. El correcto diagnóstico de una patología banal de mucosa oral, nos ha permitido actuar de manera muy precoz frente a la patología neoplásica asociada a dicha enfermedad
