ICU due to his proven severe dengue diagnosis. In follow-up tests, positive IgM serology for dengue, hematological affection was documented due to bicytopenia (anemia and thrombopenia) without evidence of external or hidden bleeding (Figure 1) requiring platelet transfusion on two occasions; it was decided to transfuse because the patient had already overcome the dengue critical phase, and this decrease was progressive until high-bleeding risk values from vital organ are associated with severe hemodynamic affection, secondary to Evans syndrome and not to a hematological manifestation of dengue.
