Resumo: | The authors present a case of a 60-year-old male patient, previously diagnosed with B-cell chronic lymphocytic leukemia, who was admitted to the Emergency Room with dyspnea. The initial evaluation revealed severe anemia (Hgb = 5.0 g/dL) with hyperleukocytosis (800.000/µL), nearly all of the cells being mature lymphocytes, a normal chest X-ray and a low arterial oxygen saturation (89%; pulse oximetry). After red blood cell transfusion, Hgb values rose (9.0 g/dL) and there was a complete reversion of the dyspnea. Yet, subsequent arterial blood gas analysis, without the administration of supplemental oxygen, systematically revealed very low oxygen saturation values (~ 46%), which was inconsistent with the patient’s clinical state and his pulse oximetry values (~ 87%), and these values were not corrected by the administration of oxygen via non-rebreather mask. The investigation performed allowed to establish the diagnosis of oxygen leukocyte larceny, a phenomenon which conceals the true oxygen saturation due to peripheral consumption by leukocytes. |

Na avaliação inicial, destacava-se uma anemia grave (Hgb = 5,0 g/dL) e hiperleucocitose (800 000/µL), correspondendo na sua quase totalidade a linfócitos maduros, uma radiografia do tórax normal e uma saturação de oxigénio baixa (89%). Após transfusão de glóbulos rubros registou-se uma elevação do valor de Hgb (9,0 g/dL) e uma reversão completa do quadro de dispneia. Porém, as gasimetrias subsequentes de reavaliação, em ar ambiente, revelaram sistematicamente valores de saturação de oxigénio muito baixos (~ 46%), discrepantes com o estado clínico do doente e com a oximetria de pulso (~ 87%), e não sofreram qualquer alteração com administração de concentrações de oxigénio por máscara. A investigação efetuada permitiu estabelecer o diagnóstico de sequestro leucocitário de oxigénio, fenómeno que mascara a verdadeira saturação de oxigénio por consumo periférico pelos leucócitos.
