Progressive Massive Splenomegaly in an Adult Patient with Kabuki Syndrome Complicated with Immune Thrombocytopenic Purpura.

Abstract

Kabuki syndrome is characterized by multiple systemic anomalies and intellectual disability. It is complicated with immunodeficiencies and autoimmune disorders. The syndrome is caused by a mutation in the KMT2D gene. We herein report a case of a Kabuki syndrome with developing immune thrombocytopenic purpura (ITP) and progressive splenomegaly. Laparoscopic splenectomy was performed and the patients' symptoms quickly disappeared with platelet recovery. After this operation, the patient had no severe complications. A sequence analysis of the KMT2D gene identified a pathogenic mutation frequently associated with ITP. Laparoscopic splenectomy is therefore considered to be a good therapeutic option for recurrent ITP and symptomatic splenomegaly with Kabuki syndrome.
