A Case of Extramedullary Plasmacytomas of Posterior Mediastinum, and Gingiva associated with Fulminant Hepatic Failure, which Developed in the Course of Multiple Myeloma / 대한혈액학회지

Multiple myeloma is usually restricted to bone marrow, but extramedullary involvement can occur in the form of plasmacytomas. Several cases of multiple myeloma which developed into mutiple extramedullary involvements have been reported. We report a case of extramedullary plasmacytomas of posterior mediastinum, and gingiva, which developed in the course of mutiple myeloma in a 57-year-old man. The patient progressed to fulminant hepatic failure resulting in rapid fatal outcome.
