Respiratory distress and hypoxemia in systemic mastocytosis.
A 25-year-old woman with documented mastocytosis developed hypoxemia with pruritus, diarrhea, headache, and hypotension on two separate occasions. The hypoxemia appeared to be related to a massive release of histamine. Resolution of the patient's symptoms was accompanied by the return of her arterial oxygen tension to normal levels.
