Large Mesenteric Gaucheroma Responds to Substrate Reduction Therapy: A New Management of Gaucheromas

Gaucheromas, which are pseudotumors consisting of a cluster of Gaucher cells, are rare complications in Gaucher's disease (GD) and reported in patients treated with enzyme replacement therapy (ERT). Gaucheromas commonly develop in the lymph nodes in the mesenteric and mediastinal regions and can cause serious complications including protein-losing enteropathy. A large mesenteric Gaucheroma showed a significant reduction in size after initiation of substrate reduction therapy (SRT) with eliglustat in an adult patient with GD type 3. Combination therapy with ERT and SRT should be considered to prevent Gaucheromas in patients with GD.
