Abstract

INTRODUCTION:

The association between anaphylactic reactions and systemic mastocytosis is well documented. However, platelet transfusionhas not previously been reported as a potential elicitor of anaphylaxis in the context of systemic mastocytosis.

CASE PRESENTATION:

We describe the clinicopathological findings of a 59-year-old Latin American man who presented to the emergency room with fatigue, leukocytosis, thrombocytopenia and mild hepatosplenomegaly. He developed two separate, temporally associated and severe anaphylactic reactions after receiving platelet transfusions. The result of a laboratory investigation for clerical errors and Coombs test was negative. Pre- and post-transfusion urine samples were negative for hemolysis. Bone marrow biopsy and aspirate smears performed demonstrated involvement by systemic mastocytosis, which had been previously undiagnosed.

CONCLUSIONS:

We posit the transfusion reaction to be an anaphylactic reaction to transfused products as a result of heightened allergic sensitivity due to the underlying systemic mastocytosis. To the best of our knowledge, this is the first reported case of a severe anaphylactic-type reaction toblood products occurring in the setting of a previously undiagnosed systemic mastocytosis. Furthermore, it seems there are no published studies closely examining the relationship between hematopoietic neoplasms and transfusion reactions in general.
