Naphthalene Poisoning Manifesting as Hemoglobinuria


  • Rajendra Prasad Government Medical College, Department of Medicine, Tanda, Himachal Pradesh, India


Reddish black discoloration of urine in absence of red blood cells (RBCs) can be a manifestation of hemoglobinuria or myoglobinuria. We report a patient who was admitted for persistent vomiting. On 2nd day of admission, his urine turned reddish black. The patient then revealed that he had ingested mothballs 1 day back to commit suicide. The patient was managed conservatively with intravenous (IV) fluids and antiemetics. Mothballs are rarely reported as a suicidal agent and most cases are related to accidental exposure of children while playing. IV hemolysis is also reported with mothball ingestion. Our patient quickly became normal within 24 h and there was no residual organ damage.
