ABSTRACT

El tumor glómico es una neoplasia vascular originada de las células del músculo liso del componente neuromioarterial, responsable del control del flujo sanguíneo microvascular. Representa el 1,6% de todos los tumores de tejidos blandos, localizándose principalmente en la zona subungüeal y clínicamente muy doloroso. Su diagnóstico puede ser tardío debido a su pequeño tamaño, manifestaciones clínicas inespecíficas y localizaciones anatómicas inusuales. El tratamiento principalmente es quirúrgico, el cual es curativo, permitiendo además la confirmación histopatológica. Se presenta el reporte de caso de una paciente de 13 años de edad con un tumor glómico de localización inusual en mucosa bucal.


The glomus tumor is a vascular neoplasm originating from smooth muscle cells of neuromyoarterial component, responsible for the control of microvascular blood flow. It represents 1.6% of all soft tissue tumors, being located mainly in the subungual area and clinically very painful. Diagnosis may be delayed because of their small size, nonspecific clinical manifestations and unusual anatomical locations. Treatment is primarily surgical, which is healing, also allowing the histopathologic confirmation. The case report of a 13-year-old patient with an unusual-located glomus tumor in the oral mucosa is presented.

ABSTRACT

El tumor de colisión es una variante poco frecuente de tumores del cérvix uterino, originados de las células de reserva de la unión escamocelular y que debe ser diferenciado de los carcinomas adenoescamosos. El objetivo del presente artículo es determinar las características morfológicas de 17 casos de tumor de colisión de cérvix uterino. La edad promedio de presentación fue 48,7 años (rango: 34-87 años). Los 4 casos con metástasis ganglionares correspondieron al componente de adenocarcinoma.


Collision tumor is an uncommon variant of cervical tumors originating from the reserve cells of squamous cell union and must be differentiated from adenosquamous carcinomas. The aim of this paper is to determine the morphological characteristics of 17 cases of collision tumor of uterine cervix, in which it was found that the average age at diagnosis was 48.7 years (range: 34-87 years). In 5 cases lymph node metastases were of the adenocarcinoma component.
