title: Late relapse of a light-chain myeloma as extramedullary plasmacytoma of the thyroid gland after second allogeneic stem-cell transplantation.
abstract: We present a rare experience with a myeloma patient who had a late relapse as isolated extramedullary plasmacytoma of the thyroid gland after a second allogeneic transplantation. We give PET/CT scan findings at diagnosis and during follow up of the disease after subsequent management. The possible pathogenesis of the late extramedullary relapse of myeloma after allogeneic stem-cell transplantation and management options are discussed.
