Although parathyroid adenoma's co-morbidity with multiple myeloma is common, extramedullary myeloma, an ectopic parathyroid adenoma has not been reported in the literature. This is the first study in literature that presents extramedullary myeloma that infiltrated ectopic parathyroid adenoma in the mediastinum after multiple myeloma treatment. In its course of relapse, the extramedullary myeloma created mass effect and no laboratory findings were present due to its non-secretory nature.eninfo:eu-repo/semantics/embargoedAccessMyelomaMetastasisAdenomaParathyroidEditorial71275275510.47391/JPMA.746Q4Q4
