Multiple Myeloma Relapsed with Skull Involvement in Plasmacytoma
Extra medullary plasmacytomas occurring as solitary (primary) tumours or secondary manifestations of multiple myeloma most often involve the upper airways and paranasal sinuses. The skull is one of the rarest sites of extra medullary plasmacytoma. Myelomatous deposits in dural reflections distant from the bony skull, i.e. tentorium and falx, are rarer, and probably result from dissection along ...
متن کاملExtramedullary Plasmacytoma Presenting as a Solitary Mass in the Intracranial Posterior Fossa
A patient with a 3-month history of headache refractory to pain medication was admitted. The CT scan and MRI showed evidence of a posterior fossa mass. This was pathologically confirmed as an extra medullary plasmacytoma (EMP). He had a pathologic fracture of the left humerus 7 years ago while the radiologist was unaware at the time of diagnosis. A solitary bone plasmacytoma (SBP) was the cause...
متن کاملSolitary plasmacytoma of the mandible - a rare entity.
Plasma cell dyscrasias (multiple myeloma, solitary plasmocytoma of bone and extra medullary plasmocytoma) are cha¬racterized by a monoclonal neoplastic proliferation of plasma cells of which Solitary plasmocytoma of bone (SPB) is a localized form. SPB is most frequently seen in vertebrae and secondarily in long bones. Its presence in jaws is extremely rare. The malignant plasma cells express mo...
متن کاملA Case of Mediastinal Extramedullary Plasmacytoma Associated with Multiple Myeloma
plastic proliferation of plasma cells arising from non-osseous sites, while the neoplastic plasma cells in multiple myeloma patients usually involve the medullary space of bones. Extramedullary plasmacytoma may be primary or secondary to marrow involvement by myeloma. Extramedullary plasmacytoma arising from the mediastinum is known to be extremely rare (1). Herein, we present a rare case of me...
متن کاملMicroRNA expression patterns in medullary and extramedullary plasmacytoma
Plasmacytomas are localized tumors of monoclonal plasma cells without evidence of significant bone marrow infiltration or systemic myeloma, comprising B2–10% of all plasma cell neoplasms. Medullary plasmacytomas classically occur in the bone of the vertebrae or skull, whereas extramedullary plasmacytomas occur in the soft tissues, most frequently in the head and neck region involving the sinuse...
