Differentiation of benign from malignant cervical lymphadenopathy by ultrasonography in children.

Abstract:

INTRODUCTION:The most common causes of cervical lymphadenopathy (LAP) are inflammatory and reactive conditions; only a small proportion have serious pathology, such as malignancy. The objective of this study was to evaluate the relationship between USG findings and histopathological diagnosis of the cervical LAP. POPULATION AND METHODS:This retrospective study comprised the cases of cervical LAP in patients aged under 20 years old followed in our center between January 2007 to December 2016. Based on pathology reports, we divided the patients into two groups: benign and malignant. Pathology results and USG findings were compared. RESULTS:After the analyze of the histopathological results and USG findings, 107 patients with persistent cervical LAP (44 malignant; 63 benign) were included in the study. Mean age of malignant and benign group were 14 ± 6.1; 11.9 ± 4.8 years, respectively. Hilar vascularity for benign LAP was highly statistically significant (P < 0.0001) and peripheral flow and mixed vascularity for malignant LAP were also statistically significant (p < 0.05). There was not a significant difference in the maximum diameter (27.3 ± 11.1 mm and 29.8 ± 12.3 mm, respectively), however, there was a significant difference in the minimum diameter between benign and malignant groups (13.7 ± 7.3 mm and 18.7 ± 8.8 mm, respectively). CONCLUSIONS:The present study suggests that there is a relationship between US and biopsy findings for the differentiation of benign from malignant LAP, especially in terms of nodal hilus and intranodal vascular pattern. :Introducción: Las causas más frecuentes de la linfadenopatía cervical son las afecciones inflamatorias y reactivas; solo unos pocos casos representan una patología seria.El objetivo fue evaluar la relación entre los hallazgos ecográficos y el diagnóstico histopatológico. Población y métodos: Este estudio retrospectivo abarcó la linfadenopatía cervical en los menores de 20 años seguidos en nuestro centro, entre enero de 2007 y diciembre de 2016. Según los informes anatomopatológicos, se dividió a los pacientes en dos grupos: benigno y maligno. Se compararon los resultados anatomopatológicos y los hallazgos ecográficos. Resultados: Después del análisis de los resultados histopatológicos y los hallazgos ecográficos, se incluyó a 107 pacientes con linfadenopatía cervical persistente (44 casos malignos; 63, benignos). La media de edad de los grupos maligno y benigno fue de 14 ± 6,1 años y de 11,9 ± 4,8 años, respectivamente. La presencia de vascularidad hiliar fue estadísticamente significativa (p < 0,0001) en la linfadenopatía benigna, mientras que el flujo periférico y la vascularidad mixta lo fueron (p < 0,05) en la linfadenopatía maligna. No se observó una diferencia significativa en el diámetro máximo (27,3 ± 11,1 mm y 29,8 ± 12,3 mm, respectivamente), pero sí en el diámetro mínimo entre los grupos benigno y maligno (13,7 ± 7,3 mm y 18,7 ± 8,8 mm, respectivamente). Conclusiones: Este estudio sugiere que existe una relación entre los hallazgos ecográficos y de la biopsia para la diferenciación entre la linfadenopatía benigna y maligna, en especial, en el patrón vascular intraganglionar y el hilio ganglionar.
