RESUMEN Introducción: El carcinoma adenoide quístico es una neoplasia originada en glándulas exocrinas de todo el cuerpo, principalmente en glándulas salivales mayores. En cavidad nasal y senos paranasales es poco frecuente y se caracteriza por presentar una alta frecuencia de recurrencia y de metástasis a distancia posterior a su remisión y a pesar de su tratamiento. Objetivo: Describir características de una serie de casos de pacientes con carcinoma adenoide quístico de cavidad nasal y senos paranasales operados. Material y método: Estudio descriptivo-retrospectivo. Período enero de 2012 y enero de 2017. La información se obtuvo a partir de las fichas electrónicas de la Clínica Las Condes. Se describen procedencia, edad y sexo, características clínicas, hallazgos anatomopatológicos, métodos diagnósticos, tratamiento, evolución. Resultados: Total de 5 pacientes operados, 3 mujeres y 2 hombres. La edad promedio fue de 63 años, con rango de 33 años a 90 años de edad. 100% de los casos sin factores asociados. La presentación clínica más frecuente fue la obstrucción nasal unilateral, seguida por el dolor facial. Dos pacientes se presentaron con diagnóstico inicial, dos por recurrencia y uno por persistencia. En tres casos el tumor se origina de seno maxilar y en dos en seno etmoidal. Todos presentaron enfermedad avanzada, etapa IV y III. Tres pacientes histológicamente fueron de bajo grado y dos de alto grado. En los cinco casos el tratamiento primario fue quirúrgico, en el 60% endoscópico, 20% abierto y 20% combinado. En cuatro casos se usó radioterapia posoperatoria y en tres de éstos, quimioterapia concomitante. Todos se encuentran sin signos de recidiva tumoral en último control. Conclusiones: El carcinoma adenoide quístico de cavidad nasal y senos paranasales es bastante infrecuente, su incidencia es menor a 1/100.000 casos por año. Es más frecuente en mujeres entre 40 y 50 años. Se identifica más con su origen en el seno maxilar (50%) y de patrón cribiforme. Clínicamente se presenta en estadíos avanzados ya que en etapa precoz es asintomático o presenta clínica inespecífica inflamatoria. El diagnóstico se realiza con biopsia complementada con imagenología. El tratamiento más utilizado es la cirugía endoscópica o abierta asociado a radioterapia posoperatoria, a pesar de la cual, se presentan con alta recurrencia a largo plazo.
ABSTRACT Introduction: Adenoid Cystic Carcinoma is a neoplasm originating in exocrine glands throughout the body, mainly in the major salivary glands. In the nasal cavity and paranasal sinuses is rare and characterized by a high frequency of recurrence and distant metastasis after remission and despite its treatment. Aim: To describe characteristics of a series of patients with operated adenoid cystic carcinoma of the nasal cavity and paranasal sinuses. Material and method: Descriptive-retrospective study. Period January 2012 and January 2017. The information was obtained from the electronic tabs of the Las Condes Clinic. It describes origin, age and sex, clinical characteristics, anatomopathological findings, diagnostic methods, treatment, evolution. Results: Total 5 patients operated, 3 women and 2 men. The average age was 63 years, ranging from 33 years to 90 years of age. 100% of the cases without associated factors. The most frequent clinical presentation was unilateral nasal obstruction, followed by facial pain. 2 patients presented with initial diagnosis, 2 due to recurrence and 1 due to persistence. In 3 cases the tumor originates from the maxillary sinus and in 2 in the ethmoidal sinus. All had advanced disease, stage IV and III. 3 patients were histologically low grade and 2 high grade. In all 5 cases, the primary treatment was surgical, 60% endoscopic, 20% open and 20% combined. In 4 cases, postoperative radiotherapy was used and in 3 of this concomitant chemotherapy. All are without signs of tumor recurrence in the last control. Conclusion: Adenoid Cystic Carcinoma of the nasal cavity and paranasal sinuses is quite infrequent; its incidence is less than 1/100,000 cases per year. It is more common in women between 40 and 50 years. It is identified more with its origin in the maxillary sinus (50%) and cribriform pattern. Clinically it presents in advanced stages since at an early stage, it is asymptomatic or it presents nonspecific inflammatory clinic. Diagnosis is performed with biopsy supplemented with imaging. The most commonly used treatment is endoscopic or open surgery associated with postoperative radiotherapy, despite which, they present with high recurrence in the long term.
