Osteitis/bone marrow edema are the initial manifestations of active sacroiliitis. In the differential diagnosis of sacroiliitis, sacral SIFs and bone tumors, such as plasmacytoma
and osteosarcoma, should be suspected for bone narrow edema/osteitis-like appearance on MRI.
Extramedullary Solitary Plasmacytoma
: Demonstrating the Role of (18)F-FDG PET Imaging.
Moreover, the study in  takes tongue amyloidosis as a possible diagnostic indicator for the disease of plasmacytoma
. An increasing number of researches endeavour to explore the potential of tongue diagnosis to infer systemic disorders.
Differential considerations included a second primary malignancy, infectious process, extramedullary hematopoiesis, and in a different clinical scenario, the possibility of plasmacytoma
should be considered.
Lesions containing plasma cells in the thyroid range from HT, solitary plasmacytoma
, PCG, IgG4-related disease, IMT, and Riedel thyroiditis (Table 2).
Only a few case reports have been published so far and they were focused on Solitary Plasmacytoma
of sternum, Amyloidosis with Multiple Myeloma and lymphoplasmacytic malignancies.
When only one mass is present, it is known as a plasmacytoma
while more than one is known as multiple myeloma.
Reported neoplasias in bald eagles include thyroid adenocarcinoma, teratoma, plasmacytoma
, and myeloproliferative disease.
Atrophoderma of Pasini and Pierini associated with extramedullary plasmacytoma
. Clin Exp Dermatol.
Solitary plasma cell tumors (plasmacytoma
) represents 2.4 percent of all canine tumors.
Subjects were selected for inclusion if they met the following criteria: (1) the diagnosis of MM confirmed by the presence of an M-component in serum and/or urine plus clonal plasma cells in the bone marrow and/or a documented clonal plasmacytoma
, (2) digital image data available for retrospective analysis, and (3) the time interval between assessment of hematological and immunologic parameters and [sup.18]F-FDG PET/CT <3 weeks.
Twenty-five cases of conventional OSA and 25 cases of OPBT (consists of angiosarcoma, chondrosarcoma, chordoma, Ewing's Sarcoma, malignant giant cell tumour, low grade fibromyxoid sarcoma, and plasmacytoma
) were included in this study.
