ABSTRACT

Las neoplasias malignas de origen linfoide corresponden a un complejo grupo de enfermedades cuyo diagnóstico es complicado, ya que requiere la aplicación de pruebas inmunohistoquímicas, un exhaustivo análisis por parte del equipo histopatológico, así como también una muestra representativa del tejido a examinar. Se presenta el caso de un paciente previamente diagnosticado con linfoma no-Hodgkin estirpe T, con manifestación clínica en cavidad oral, el cual presentó una mala respuesta al esquema quimioterapéutico inicial. Debido al fracaso terapéutico, se solicitaron nuevas biopsias y análisis inmunohistoquímicos, siendo la muestra de cavidad oral la que confirma el diagnóstico, esta vez acertado, de linfoma linfoblástico de células T. Se modifica el esquema terapéutico a uno de mayor intensidad, logrando una evolución favorable de la enfermedad. El presente artículo corresponde al primer caso de linfoma linfoblástico de células T con localización en maxilar superior reportado en la literatura. Se recalca la dificultad diagnóstica de los variados tipos de linfomas y destaca la importancia de los exámenes complementarios para lograr un correcto diagnóstico y manejo de esta patología. (AU)


Malignant neoplasms of lymphoid origin correspond to a complex group of diseases whose diagnosis is difficult since it requires the application of immunohistochemical tests, an exhaustive analysis by the histopathological team as well as a representative sample of the tissue to be examined. We present the case of a patient previously diagnosed with non-Hodgkin’s lymphoma type T, with clinical manifestation in the oral cavity, who presented a poor response to the initial chemotherapeutic scheme. Due to the therapeutic failure, new biopsies and immunohistochemical analysis were requested, being the oral cavity sample the one that confirmed the diagnosis, this time correctly, of T-cell lymphoblastic lymphoma, thus modifying the initial therapeutic scheme to one of greater intensity, achieving a favorable evolution of the disease. The present article corresponds to the first case of T-cell lymphoblastic lymphoma with maxillary location reported in the literature. It emphasizes the diagnostic difficulty of the different types of lymphomas and highlights the importance of complementary examinations to achieve a correct diagnosis and management of this pathology.We believe that this new, relatively simple technique can be an alternative to complex surgeries that involve the use of complicated bone grafts, with the consequent savings in time and morbidity for patients who associate maxillary hypoplasia and edentulism with severe bone atrophy.
