Antrochoanal polyp mimicking juvenile nasoangiofibroma.

Antrochoanal polyp is a benign lesion, usually arising from the maxillary sinus extending posteriorly into the nasopharynx. Typically it presents as a unilateral nasal obstruction with mucopus rhinorrhea, sleep disturbance, postnasal drip, and mouth breathers. Epistaxis is an extremely rare complaint. Unilateral nasal mass presenting in a teenage boy will increase the suspicion of juvenile nasoangiofibroma. We report a teenage with extensive unilateral nasal mass with such presentation, which later turned out to be antrochoanal polyp.

Nasoangiofibroma juvenil: una revisión actualizada del diagnóstico, clasificación y tratamiento / Juvenile nasopharingeal angiofibroma: a current review of diagnosis, clasification and treatment

Objetivo: Realizar una recopilación de datos acerca del nasoangiofibroma juvenil (NAF) permitiendo aclarar conceptos en cuanto al diagnóstico, clasificación y aproximación del manejo. Diseño: Revisión de la literatura. Método: Se recolectaron datos históricos, anatómicos, etiológicos, las múltiples clasificaciones adoptadas hasta el momento, los distintos tratamientos propuestos y las indicaciones sugeridas según la Rinología actual. Conclusiones: El NAF es un tumor de naturaleza benigna, ampliamente vascularizado, de comportamiento agresivo dada su propiedad de erosión y extensión, con pronóstico favorable cuando su diagnóstico y tratamiento es temprano. La embolización es un aspecto fundamental en el adecuado control vascular e intraquirúrgico de la lesión. El manejo endoscópico hadisminuido la morbilidad, la estancia hospitalaria y las complicaciones generadas por los abordajes externos. Ocasionalmente se requiere de abordajes quirúrgicos combinados o el uso de terapéuticas ablativas adicionales. El nasoangiofibroma juvenil requiere de un manejo interdisciplinario, pues plantea un reto diagnóstico, terapéutico intervencionista y quirúrgico.

Objective: To collect data about Juvenile Nasopharyngeal Angiofibroma (JNA), clarifying concepts about diagnosis, classification and management approach. Design: Review of the literature. Method: Data were collected historical, anatomical, etiological, multiple classifications adopted so far, the various proposed treatments and the indications suggested by the current Rhinology. Conclusions: The NAF is a benign tumor, extensively vascularized, aggressive behavior because of its ownership of erosion and extension, with a favorable prognosis when diagnosis and treatment is early realized. Embolization is a fundamental aspect of proper control and intraoperative vascular injury. Endoscopic treatment has decreased the morbidity, hospital stay and complications caused by external approaches. Occasionally requires combined surgical approaches or the use of additional ablative therapy. The Juvenile angiofibroma requires interdisciplinary management; it poses diagnostic, interventional and surgical challenge therapy.

Nasoangiofibroma juvenil en un paciente adulto masculino / Juvenile nasopharyngeal angiofibroma in an adult male

El nasoangiofibroma juvenil es un tumor infrecuente, que comprende el 0,05 por ciento de los tumores de cabeza y cuello, histológicamente es benigno, pero localmente se comporta como invasivo, tiene una predilección especial por la nasofaringe y pacientes adolescentes de sexo masculino. Es un tumor altamente vascular, la epistaxis recurrente y la obstrucción nasal son los dos síntomas más comúnmente referidos por los pacientes y puede comprometer la vida secundaria al sangrado o la extensión intracraneana. Aunque generalmente se presenta en adolescentes de sexo masculino, se han descrito algunos casos en mujeres y adultos. Este artículo presenta un caso inusual de nasoangiofibroma juvenil en un paciente masculino de 39 años, quien se presenta al servicio de urgencias del Hospital Central de la Policía por presencia de epistaxis aguda abundante, que lo lleva a choque hipovolémico, requiriendo transfusión, estabilización, arteriografía con embolización y resección de la lesión.

The Juvenile Nasopharyngeal Angiofibroma is a rare tumor, which comprises 0.05% of head and neck tumors, histologically benign, but locally is invasive, has a special predilection for the nasopharynx and male adolescent patients, is highly vascular, the recurrent epistaxis and nasal obstruction are the two most common symptoms reported by patients. These tumors can compromise the life secondary to bleeding or intracranial extension. Although it usually occurs in male adolescents have been few cases in women and adults, this article presents an unusual case of juvenile nasoangiofibroma in a 39 years old male patient, who presents to the emergency department of the Central Police Hospital by the presence of abundant and acute epistaxis, which leads to hypovolemic shock, requiring transfusion, stabilization, arteriography with embolization and resection of the lesion.

Tratamento cirúrgico de nasoangiofibroma sem embolização / Surgical Treatment of Non-embolized Patients with Nasoangiofibroma

Nasoangiofibroma juvenil (NAFJ) é um tumor incomum que se localiza na região do forame esfenopalatino. A cirurgia combinada à embolização pré-operatória tem sido a opção terapêutica mais empregada nos pacientes com NAFJ sem invasão intracraniana. O objetivo desse estudo é avaliar a viabilidade do tratamento cirúrgico do nasoangiofibroma em pacientes estágios I- III de Fisch, sem uso de embolização pré- operatória. MATERIAL E MÉTODO: Estudo descritivo, retrospectivo, utilizando-se dados de revisão de prontuário de quinze pacientes com NAFJ estágio I a III de Fisch submetidos à cirurgia sem embolização pré-operatória, entre os anos de 2000 e 2005. RESULTADOS: Dos quinze pacientes, sete pacientes foram submetidos à cirurgia endoscópica, quatro via transmaxilar, três via endoscópica e transmaxilar e um via transmaxilar e transpalatina. Seis pacientes necessitaram de hemotransfusão no intra-operatório, com média geral de 1.3 bolsa/paciente. Nenhum caso de mortalidade ou morbidade significativa foi registrado. Onze dos quinze pacientes foram acompanhados por tempo médio de doze meses com taxa de recidiva de 27 por cento. Quatro pacientes perderam seguimento. CONLUSÃO: A ressecção de NAFJ classes I- III foi realizada com segurança em pacientes não-embolizados, com taxa de sangramento intraoperatório, ocorrência de complicações e taxa de recorrência próximas dos valores pesquisados na literatura para pacientes embolizados.

Juvenile nasopharyngeal angiofibroma (JNA) is an uncommon tumor of the sphenopalatine foramen. Surgery combined with preoperative embolization has been the treatment of choice for JNA patients without intracranial invasion. This study aims to assess the viability of surgically treating non-embolized patients with JNA (types I-III according to Fisch). MATERIAL AND METHOD: This is a retrospective, descriptive study based on the medical records of 15 patients with histologically confirmed JNA (Fisch’s types I- III), who underwent surgical treatment without pre-op embolization in our institution between 2000 and 2005. RESULTS: Seven of the fifteen patients were approached endoscopically, four through the transantral approach, three were treated with the combined transmaxillary and endoscopic approach, and one with the combined transmaxillary and transpalatal approach. Six patients required intraoperatory blood transfusion, averaging volumes of 1.3 unit/patient. There were no cases of death or significant morbidity. Eleven of the fifteen patients were followed for an average of twelve months and 27 percent of them relapsed. Four patients did not comply with the follow-up scheme. CONCLUSION: Resection of JNF types I-III was safely completed in non-embolized patients. The observed levels of intraoperative bleeding, occurrence of complications, and rates of recurrence were close to those seen in embolized patients as found in the literature.
