Linfoma anaplásico de grandes células, ALK-negativo: um caso raro com características histopatológicas e imuno-histoquímicas
Conteúdo do artigo principal
Resumo
Relatamos um caso de linfoma anaplásico de grandes células (LAGC), ALK-negativo, diagnosticado em uma paciente de 27 anos com linfadenopatia difusa e sintomas constitucionais. O exame histopatológico revelou camadas de grandes células linfoides pleomórficas, e a imuno-histoquímica demonstrou positividade para CD30 com negatividade para ALK. Este caso destaca os desafios diagnósticos e terapêuticos associados a este raro subtipo de linfoma de células T e contribui para a crescente literatura sobre LAGC ALK-negativo.
