ResumoObjetivo: Estudar o perfil clínico-patológico de crianças indianas com linfadenopatia cervical e o papel da citologia aspirativa por agulha fina com ênfase especial na tuberculose como causa. Resultados: A hiperplasia reativa foi o tipo mais comum de linfadenite, seguida da granulomatosa. Os linfonodos do triângulo posterior unilateral foram o grupo afetado com maior freqüência no grupo de linfadenopatia cervical tuberculosa. A aspiração por agulha fina, seguida da coloração de Ziehl-Neelsen, histopatologia e cultura em associação, obteve sucesso em realizar o diagnóstico em 85,7% dos casos de etiologia tuberculosa. Métodos Conclusões:A aspiração por agulha fina é uma ferramenta diagnóstica valiosa no tratamento de crianças com apresentação clínica de linfonodos cervicais aumentados. A técnica reduz a necessidade de procedimentos mais invasivos e dispendiosos, principalmente em países em desenvolvimento.Cultura e histopatologia, entretanto, devem ser consideradas em casos nos quais a citologia aspirativa por agulha fina não é diagnóstica.J Pediatr (Rio J). 2008;84(5):449-454: Linfadenopatia cervical, citologia aspirativa por agulha fina, crianças. AbstractObjective: To study the clinicopathological profile of children from India with cervical lymphadenopathy and the role of fine-needle aspiration cytology with special emphasis on tuberculosis as a cause. Methods:A total of 89 children in the age group of 10 months to 12 years, presenting to our hospital from April 2004 to March 2005, were included. All the patients underwent thorough clinical and investigational assessment vis-à-vis cervical lymphadenopathy. Outcome measurements included clinical status and ability of conventional tests to categorize different types of lymphadenopathy and their utility in diagnosing tubercular lymphadenitis. Interobserver variability was analyzed measuring kappa test and was found to be in agreement. Results:Reactive hyperplasia was the most common type of lymphadenitis, followed by granulomatous involvement. Unilateral posterior triangle lymph nodes were the most commonly affected in the tubercular cervical lymphadenopathy group. Fine-needle aspiration followed by Ziehl-Neelsen staining, histopathology and culture in combination were able to perform the diagnosis in 85.7% of cases affected with tubercular etiology. Conclusions:Fine-needle aspiration is a valuable diagnostic tool in the management of children with the clinical presentation of enlarged cervical lymph nodes. The technique reduces the need for more invasive and costly procedures, especially in a Third World country. Culture and histopathology, however, should be considered in cases where repeated fine-needle aspiration cytology is non-diagnostic.J Pediatr (Rio J). 2008;84(5):449-454: Cervical lymphadenopathy, fine-needle aspiration cytology, children.
