Anaphylactic reaction to platelet transfusion as the initial symptom of an undiagnosed systemic mastocytosis: a case report and review of the literature.

Introduction: The association between anaphylactic reactions and systemic mastocytosis is well documented. However, platelet transfusion has 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.

Post-transplant lymphoproliferative disorder presented as small bowel intussusception in adult liver transplant patient.

Intestinal obstruction after liver transplant is a rare complication, with diverse clinical manifestations. Intestinal adhesion is the most common cause. However, internal hernia, abdominal wall hernia, and neoplasm are also reported.
