Masa cervical de origen infrecuente / Neck mass with infrequent origin

Varón de 67 años de edad diagnosticado de adenocarcinoma de próstata que refiere disfagia, disfonía y la aparición de una masa laterocervical. En una tomografía computarizada se aprecia una lesión cervical de partes blandas, osteolítica, la cual es resecada y cuyo estudio anatomopatológico fue compatible con metástasis de adenocarcinoma de próstata(AU)

We report the case of a 67-year-old male diagnosed with prostate adenocarcinoma, who referred dysphagia, dysphonia and noticed the appearance of a laterocervical mass. A CT scan revealed an osteolytic soft tissue neck lesion, which was resected. Its anatomical-pathological study was compatible with metastasis of prostate adenocarcinoma(AU)

[Neck mass with infrequent origin]. / Masa cervical de origen infrecuente.

We report the case of a 67-year-old male diagnosed with prostate adenocarcinoma, who referred dysphagia, dysphonia and noticed the appearance of a laterocervical mass. A CT scan revealed an osteolytic soft tissue neck lesion, which was resected. Its anatomical-pathological study was compatible with metastasis of prostate adenocarcinoma.

[Primary tumours of the parapharyngeal space. Our experience in 51 patients]. / Tumores primarios del espacio parafaríngeo. Nuestra experiencia en 51 pacientes.

INTRODUCTION AND OBJECTIVES: Tumours of the parapharyngeal space are rare, representing only 0.5 % of head and neck oncology. The aim of this study is to present our experience with the diagnosis and therapies for these tumours. PATIENTS AND METHOD: This study is a retrospective review of 51 patients diagnosed as having tumours of the parapharyngeal space and treated surgically between 1984 and 2006. Tumours originating in the deep lobe of parotid gland were excluded. RESULTS: Seventy percent of the parapharyngeal space neoplasms were benign and thirty percent malignant. Pleomorphic adenoma was the most common neoplasm (37 %), followed by miscellaneous benign tumours (34 %), paraganglioma (21 %), and neurogenic tumours (8 %). Surgery was chosen in all case, with the transcervical approach used in 32 cases, the cervical-transparotid approach in 13 cases, the transmandibular approach in 4 cases (with mandibulectomy in 1 patient), the transoral approach in 1 case, and the infratemporal fossa approach in 1 case. The most common complications were those deriving from damage to nerve structures. CONCLUSIONS: Most parapharyngeal space tumours can be removed surgically with a low rate of complications and recurrence. The transcervical approach is the most frequently used.

Tumores primarios del espacio parafaríngeo. Nuestra experiencia en 51 pacientes / Primary tumours of the parapharyngeal space. Our experience in 51 patients

Introducción y objetivos. Los tumores originados en el espacio parafaríngeo son poco frecuentes, y representan el 0,5 % de la enfermedad oncológica de cabeza y cuello. El objetivo de este estudio es presentar nuestra experiencia en el diagnóstico y el tratamiento de estos tumores. Pacientes y método. Realizamos un estudio retrospectivo de 51 pacientes, diagnosticados y tratados quirúrgicamente de una tumoración parafaríngea, durante el período comprendido entre 1984 y 2006. Se excluyeron los tumores originados en el lóbulo profundo de la parótida. Resultados. El 70 % de las neoplasias del espacio parafaríngeo fueron de naturaleza benigna y el 30 %, maligna. El adenoma pleomorfo fue el tumor más frecuente (37 %), seguido por un grupo de tumores de origen misceláneo (34 %), los paragangliomas (21 %) y los tumores de origen neurogénico (8 %). En todos los casos el tratamiento fue quirúrgico. Se realizó un tratamiento transcervical en 32 pacientes, un tratamiento cervical-transparotídeo en 13 pacientes, un tratamiento transmandibular en 4 pacientes (sólo se precisó de mandibulectomía en un caso), un caso de tratamiento transoral y un caso de tratamiento infratemporal tipo A. Las complicaciones más frecuentes fueron las derivadas de lesiones de estructuras nerviosas. Conclusiones. La mayoría de los tumores localizados en el espacio parafaríngeo son subsidiarios de tratarse de forma quirúrgica, con una tasa baja de complicaciones y

Papilomas invertidos nasosinusales / Sinonasal Inverted Papillomas

Se realiza un estudio y una revisión de la literatura sobre los papilomas invertidos nasosinusales, con descripción de la epidemiología y la etiopatogenia, la presentación clínica y las exploraciones necesarias para su diagnóstico y clasificación. Se analizan los abordajes quirúrgicos propuestos y se describe la técnica endoscópica para la extirpación completa de las lesiones, que deberá ser combinada con abordajes abiertos tipo Cadwell-Luc, paralateronasales o craneofaciales, si la extensión de la tumoración rebasa los límites asequibles con una técnica puramente endoscópica (AU)

The present article provides an analysis and review of the literature on sinonasal inverted papillomas, with description of the epidemiology, etiopathogenesis, clinical presentation and investigations required for their diagnosis and classification. The surgical approaches proposed are analyzed and the endoscopic technique for complete extirpation of these lesions is described. This technique should be combined with Caldwell-Luc-type open approaches or paralateronasal or craniofacial approaches if, due to its extension, the tumor cannot be reached by the endoscopic technique alone (AU)
