RESUMO
Resumen La enfermedad de Kikuchi-Fujimoto es un trastorno benigno que afecta principalmente a mujeres jóvenes, se caracteriza por adenopatías de predominio en la región cervical, asociadas a fiebre y leucopenia. Aunque de etiología desconocida, hay evidencia de que una infección viral o una enfermedad autoinmune puede desencadenar la enfermedad. Se reporta un caso infrecuente en Colombia de enfermedad de Kikuchi-Fujimoto en una paciente con lupus eritematoso sistémico.
Abstract Kikuchi-Fujimoto disease is a benign disorder that mainly affects young women, and is characterised by predominantly cervical lymphadenopathy associated with fever and leukopenia. Although of unknown aetiology, there is evidence that a viral infection or autoimmune disease can trigger the disease. An uncommon case in Colombia is presented of Kikuchi-Fujimoto disease in a patient with Systemic Lupus Erythematosus.

Kikuchi-Fujimoto disease also known as histiocytic necrotizing lymphadenopaty (HNL) is a rare entity, originally described in Japanese population, although currently it has been described all over the world. It is more frequent in young women and it is usually located in cervical lymph nodes. We report 14 cases of HNL in Mexican population, their clinicopathological and immunohistochemical study as well as a comparative study with other necrotizing lymphadenopaties due to B or T-cell lymphomas, tuberculosis, Epstein Barr virus infection, and non-specific necrosis. In our study we found that there was more expression of the immunomarkers CD68, MPO, CD123 and antikerat in OSCAR in the cases of HNL in contrast with the lesser or even null expression of the same markers in the necrotized lymph nodes of the comparative study group.
La enfermedad de Kikuchi-Fujimoto o linfadenitis histiocítica necrosante (LHN) es una entidad poco frecuente, inicialmente descrita en población japonesa. Sin embargo, actualmente se ha descrito alrededor de todo el mundo. Es más frecuente en mujeres jóvenes y su localización habitual es en ganglios linfáticos cervicales. Presentamos estudio clinicopatológico de 14 casos de LHN en pacientes mexicanos, y los comparamos con linfadenitis necrosantes secundarias a linfomas B y T, tuberculosis, virus de Epstein Barr y necrosis inespecífica. Encontramos mayor expresión de los anticuerpos CD68, MPO, CD 123 y antiqueratina OSCAR en los casos de LHN comparados con la expresión baja o nula de los mismos anticuerpos en las necrosis ganglionares del grupo comparativo.
