ABSTRACT

La linfohistiocitosis hemofagocítica (LHH) por Histoplasma capsulatum, presentación rara de la histoplasmosis diseminada, es causada por la fagocitosis de las células hematopoyéticas por macrófagos tisulares. Presentamos el caso de un paciente masculino de 44 años con trasplante renal que asiste por fiebre sin otra sintomatología. Inicialmente se obtiene una gota gruesa positiva para P. vivax, iniciando manejo antimalárico. A los 2 días de tratamiento, el paciente presenta disfunción multiórganica, se rectifica diagnóstico en centro de referencia reportando en extendido de sangre periférica la presencia de levaduras de H. capsulatum en polimorfonucleares, resultado confirmado con prueba de inmunodifusión. Se ajusta manejo, pero el paciente fallece. El diagnóstico de infecciones por gérmenes inusuales con presentaciones inespecíficas es un reto en pacientes con inmunosupresión.


Hemophagocytic Lymphohistiocytosis (HLH) induced by Histoplasma capsulatum is a rare entity who is characterized by phagocytosis of hematopoietic cells by tissue macrophages. A 44-year-old male patient with kidney transplantation was admitted to our ambulatory service with fever. Initially, we performed a thick drop test who was positive for P. vivax, so antimalarial therapy was initiated. Patient then progressed to multiple organ dysfunction after 2 days of treatment. Thus, a reference center went back over the blood smear which revealed the presence of yeast cells H. capsulatum within polymorphonuclear cells. This result was confirmed by an immunodifussion assay. Despite of antifungal treatment, patient passed away. The diagnosis for unusual microorganism with unspecific clinical presentation could be a challenge in immunosupressive patients.
