Kikuchi-Fujimoto disease. An unusual disease

ABSTRACT

Kikuchi-Fujimoto disease is self-limited, has a good prognosis, is diagnosed histopathologically, is more common on the Asian continent, in women and in those under the age of 40, and is usually diagnosed by exclusion. We present the case of a 20-year-old male patient with no significant medical history who consulted due to persistent fever, enlarged lymph nodes, gastrointestinal symptoms and weight loss. He debuted with pancytopenia, elevated acute phase reactants and altered liver function, and underwent an excisional lymph node biopsy, whose findings were compatible with Kikuchi-Fujimoto disease. He was treated symptomatically with NSAIDs and was followed up one month after discharge, at which time there was no evidence of recurrent fever or other additional symptoms.

RESUMEN

La enfermedad de Kikuchi Fujimoto es autolimitada, de buen pronóstico, de diagnóstico histo-patológico, cuya incidencia es mayor en el continente asiático en mujeres, en menores de 40 años y usualmente es un diagnóstico de exclusión. Presentamos el caso de un paciente masculino de 20 años sin antecedentes patológicos, quien consultó por fiebre persistente, adenopatías, síntomas gastrointestinales y pérdida de peso; debutó con pancitopenia, aumento de reactantes de fase aguda, alteración de función hepática y en quien se le practicó biopsia excisional de ganglio, la cual evidenció hallazgos compatibles con la enfermedad de Kikuchi Fujimoto. Se hace manejo sintomático con AINES y se realiza control al mes de egreso, donde no hay evidencia de recurrencia de picos febriles u otros síntomas adicionales. (Acta Med Colomb 2022; 47.
