Intracranial plasmacytomas are an uncommon presentation of extramedullary relapse of multiple myeloma. The optimal management of extramedullary plasmacytomas remains unclear, with initial reports of bortezomib showing promising clinical results. We describe a case of multiple extracellular, including intracranial, plasmacytoma, with no evidence of marrow involvement, in a patient with relapsed ...
Extramedullary plasmacytoma involves organs outside the bone marrow; however, involvement of the pancreas is rare. We recently experienced a case of extramedullary plasmacytoma of the pancreas that was diagnosed by endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA). EUS-FNA, which has a high diagnostic accuracy and an excellent safety profile, is the modality of choice for estab...
BACKGROUND Extramedullary hematopoiesis is the proliferation of hematopoietic cells outside bone marrow secondary to marrow hematopoiesis failure. Extramedullary hematopoiesis rarely presents as a mass-forming hepatic lesion; in this case, imaging-based differentiation from primary and metastatic hepatic neoplasms is difficult, often leading to biopsy for definitive diagnosis. We report a case ...
Extramedullary recurrences with or without bone marrow involvement are reported in up to a half of leukemic relapses after bone marrow transplantation. Extramedullary relapse of acute lymphoblastic leukemia (ALL) in the kidney after allogeneic stem cell transplantation (allo-SCT) is rare. We herein, report an additional case with extramedullary recurrences and renal relapse after first-allograf...
We report here on a 64-year-old woman with extramedullary plasmacytoma involving the bilateral adrenal glands. Primary adrenal extramedullary plasmacytoma is extremely rare and only three cases of extramedullary plasmacytoma in the unilateral adrenal gland have currently been reported on. This case is of interest in that the bilateral adrenals were involved. In this article, we present the MRI ...
Objective: We report an unusual case of a patient with a plasma cell tumor presenting first as a primary pulmonary plasmacytoma (PPP) but then showing distinct signs of systemic spread. Case Summary: A 58-year-old woman presented with an extramedullary plasma cell tumor of the lung with additional affection of lymph nodes above and underneath the diaphragm, without apparent infiltration of the ...
T-cell prolymphocytic leukemia (T-PLL) can involve extramedullary sites, but the diagnosis is usually established by examination of blood and bone marrow. As a result, the histologic findings at extramedullary sites are poorly documented in the literature. We describe 19 extramedullary biopsy specimens from 14 patients with T-PLL. Skin (n = 10) was the most common site biopsied. T-PLL surrounde...
Extramedullary haemopoiesis resulting in spinal cord compression is rare. This report of extramedullary myeloid metaplasia in a patient with myelofibrosis serves to illustrate the value of magnetic resonance imaging (MRI) in the diagnosis and management of good neurological recovery.
Spinal epidermoids, with their well-known specific charaeteristics are usually subdural-extramedullary in location, In this report. a 3-year-old boy with intra-extramedullary epidermoid tumour assodated with an abscess is presented, This is the first
