Author(s): Lopez Rojo I, Gomez Valdazo A, Gomez Ramirez J
Multiple myeloma (MM) relapse following allotransplantation is rare, and when it does occur, it tends to be located in the bone marrow. Thyroid gland invasion by plasma cells is an uncommon finding in the literature. It is important to be aware that in some patients the disease manifests as apparent solitary extramedullary plasmocytoma, though further investigation reveals a plasma cell tumor in other sites We present a case of relapsed MM presenting as a rapidly growing thyroid mass.
