Hemolytic anemia presenting as hemoglobinuria from intentional paradichlorobenzene mothball ingestion

A 24-year-old Filipino male was diagnosed with hemolytic anemia when he presented with abrupt onset of anemia, hemoglobinuria, and increased bilirubins, after intentionally ingesting mothballs containing paradichlorobenzene. He was transfused with six units of packed red blood cells (PRBC) and was discharged improved. Paradichlorobenzene, a known oxidant, causes denaturation and precipitation of hemoglobin. These precipitates form Heins bodies within the erythrocytes that are removed by the reticuloendothelial system, fragmenting cells to produce hemoytic anemia from paradicholorobenzene ingestion as confirmed by the UP-National Poison Management and Control Center.
