This study reviews their imaging spectrum in 12 patients.CONCLUSION
. Imaging findings of an extramedullary plasmacytoma on radiograph and computed tomography can be nonspecific and can resemble other entities such as lymphoma, metastases, chondrosarcomas, or giant cell tumors The diagnosis of extramedullary plasmacytoma was established on the basis of the presence of large aggregates of atypical plasma cells that often infiltrated adjacent structures. The monoclonal nature of the plasma cells was confirmed by means of immunoperoxidase staining for kappa and lambda immunoglobulin light chains Extramedullary myeloma can occur contiguously with bony structures (arrows) or can be noncontiguous with bone (arrowheads). It is presumed that contiguous extramedullary myeloma occurs owing to contiguous extraskeletal extension of myelomatous masses, whereas noncontiguous extramedullary myeloma develops by hematogenous spread of plasma cells
Extramedullary plasmacytomas are rare and can occur at any site. The imaging results are often nonspeciﬁc. This report highlights the radiographic, sonographic and cross-sectional imaging features of extramedullary plasmacytomas. Key words: plasmacytoma; multiple myeloma; plasma cell tumour. Introductio The diagnosis of EMP requires demonstration of a monoclonal plasma cell infiltrate with no evidence of myeloma at any other site. Therefore, patients with presumed solitary plasmacytoma of bone or soft tissue (extramedullary) plasmacytoma should undergo a radiological bone survey and MR imaging to ensure that only one lesion is present

KAPADIA, MD Extramedullary plasmacytoma (EMP) is a rare plasma cell malignancy of soft tissues.' The majority (80% to 90%) of EMPs involve the head and neck,' including the upper respiratory tract Extramedullary plasmacytoma of the breast (EPB), a manifestation of multiple myeloma (MM), is very rare. It is important to recognize the imaging findings of EPB because it may be the first manifestation of relapsed MM.

The median time of progression to multiple myeloma following diagnosis was 25 and 45 months in solitary plasmacytoma of the bone and extramedullary plasmacytoma, respectively . The radiologic findings of this disease have not been well documented thus far Extramedullary plasmacytoma of the breast is rare. It is important to recognize the imaging findings and include it as a differential consideration in multiple myeloma patients with a breast mass.

EMP involving gastrointestinal is rare
Extramedullary plasmacytoma (EP) can either be a concurrent presentation of MM (7%) or develops later after the diagnosis of MM (6%). SEP, a localized plasma dyscrasia arising outside of bone marrow, accounts for only 3% of all plasma cell disorders The most common manifestation is bone involvement with radiologic skeletal findings of diffuse osteopenia or osteolytic bone lesions. A total of 7 - 18% of MM cases are associated with extramedullary (EM) involvement at the time of diagnosis . EM plasmacytoma in MM may occur during the course of disease or at relapse

Solitary plasmacytomas most frequently occur in bone (plasmacytoma of bone), but can also be found outside bone in soft tissues (extramedullary plasmacytoma) . Why some patients develop multiple myeloma and others a single plasmacytoma is not understood, but might be related to differences in cellular adhesion molecules or chemokine receptor.

Abstract: Solitary extramedullary plasmacytoma, an extremely rare case which accounts for about 3% of all plasma cell neoplasms, often occurs in the head and neck region such as para nasal sinuses, nasal cavity and oral cavity, it also occurs in the lymph nodes, lungs, thyroid, intestine, liver, pancreas, testis, breast, or skin.Isolated primary plasmacytoma of adrenal is extremely rare and. 7.

Extramedullary plasmacytoma of th Extramedullary plasmacytoma (EMP) is a rare entity belonging to the category of non-Hodgkin lymphoma. EMPs make up 4% of all plasma cell tumors and occur mainly in the upper aerodigestive tract (UAD) It is defined by the presence of more than 10% clonal plasma cells in the bone marrow (or biopsy-proven extramedullary plasmacytoma), together with end-organ damage attributable to the plasma cell disorder. 7-20% of patients have clinical or radiological evidence of extramedullary plasmacytoma at the time of diagnosis
Solitary plasmacytomas most frequently occur in bone but can also be found outside bone in soft-tissues.1 MM is usually confined to the bone marrow2; extramedullary disease (EMD) in MM is rare and occurs in 6%-8% of newly diagnosed MM patients and 10%-30% of MM patients later in the course of the disease.3 EMD can develop in any tissue. Solitary or multiple extramedullary plasmacytomas have been described in the liver, spleen, lymph nodes, kidneys, subcutaneous tissues, and brain parenchyma. Extramedullary involvement may be suspected in patients who have more aggressive features of myeloma Diagnostic Criteria. Osseous plasmacytoma/solitary plasmacytoma of bone.

Extramedullary plasmacytoma (EMP) is one of the rare plasma cell malignancies. It accounts for 3% of all plasma cell tumors and most frequently presented in the aerodigestive tract. EMP may likewise involve the urinary tract, central nervous system (CNS), thyroid, breast, testis, parotid gland, lymph nodes, and skin. Only nine cases of the adrenal EMP were reported in the literature Plasmacytoma of the jaw bones and oral cavity, as in other anatomic sites, comprises three distinct entities: multiple myeloma, solitary plasmacytoma of bone, and extramedullary plasmacytoma
Rationale: Extramedullary plasmacytomas (EMPs) are rare solitary soft tissue tumors characterized by monoclonal proliferation of plasma cells. Most lesions occur in the head and neck, but primary tracheal lesions are very rare. Patient Concerns: In this report, we describe a case of tracheal EMP discovered in a 48-year-old man who presented with a history of progressive dyspnea Most extramedullary plasmacytomas occur in the head and neck. The entire upper respiratory tract is at risk, but the sinonasal region (Fig. 28.2C,D), nasopharynx (Fig. 28.2A,B), and tonsils are preferred sites.The larynx (), oropharynx, and floor of the mouth and palate are also sites of origin.Salivary gland, tracheal, middle ear, and thyroid involvement is very unusual Extramedullary plasmacytoma (EMP) Patients with EMP have a 5-year survival rate of about 82% and 10-year disease-specific survival rate greater than 50%.  The rate of progression to multiple myeloma is lower than in SBP, ranging from 11% to 30% at 10 years.  Patients with EMP that progressed to multiple myeloma had a 5-year survival rate of 100%, compared with 33% for those with SBP.

Solitary extramedullary plasmacytoma (EMP) is less common than SBP and occurs when there is soft tissue infiltration of clonal plasma cells. There should be no evidence of bone destruction or occult disease elsewhere. EMP must be distinguished from reactive plasmacytoma, plasma cell granuloma and lymphoma. Definitions. Localized clonal proliferation of plasma cells. Solitary bone plasmacytoma. Clonal proliferation of plasma cells centered in bone marrow. Solitary extramedullary plasmacytoma. Clonal proliferation of plasma cells in extramedullary location. Extramedullary plasmacytoma in presence of multiple myeloma (MM Solitary plasmacytoma of bone (SPB), also called osseous plasmacytoma, is more common in males than in females with an estimated ratio of 2:1. The median age of SPB patients is approximately 55 years. Localized radiation therapy is the first-line treatment to avoid progression to multiple myeloma
1. INTRODUCTION. Extramedullary plasmacytoma (EMP) of the head and neck usually involves the nasopharynx and paranasal sinuses. 1 Hypopharyngeal invasion is extremely rare, and only two cases have been previously reported. 2, 3 To the best of our knowledge, surgical treatment with postoperative radiation has not been reported.. 2. CASE REPORT. A 77-year-old man with essential hypertension and. Testicular plasmacytomas are rare, accounting for only 1.3% of all extramedullary plasmacytomas. The infrequency in which it is encountered, coupled with its non-specific clinical and sonographic presentation, makes its diagnosis a challenge. We present a case of a 70-year-old man with multiple myeloma, which was systemically responding to chemotherapy, who developed testicular swelling.
Most extramedullary plasmacytomas are associated with the upper respiratory tract. Primary pulmonary plasmacytomas are rare, and the treatment is surgical excision. This malignancy advances to multiple myeloma in a minority of patients.
