* The patient came in malnourished and significantly dehydrated, and his blood levels on admission were therefore falsely elevated due to hemoconcentration. It was only further on during his hospitalization, and after significant volume resuscitation, that the severity of his pancytopenia was observed.

ANC, absolute neutrophil count; HCT, hematocrit; Hgb, hemoglobin; MCV, mean corpuscular volume; PLT, platelets; T3, triiodothyronine; T4, thyroxine; TSH, thyroid-stimulating hormone; WBC, white blood cell count.
