  • A Solitary plasmacytoma of bone[SPB] is a rare disease. This paper reports a case of SPB with massive aggregation of histiocytes known as pseudo-Gaucher cells. A 40-year-old male presented with progressive paraparesis and paraesthesia. The Magnetic Resornance Image[MRI] revealed a tumor mass in the thoracic spine that occupied the three colum. The tumor invaded the epidural space of T6 vertebra with compression of the spinal cord. There were no laboratory abnormalities. It was gross totally resected and his neurological symptoms improved. The microscopic examination revealed a plasmacytoma with massive aggregation of histiocytes. Futher neuroradiological studies were carried out and no other lesions were detected.

  • Solitary plasmacytoma of the bone, and especially of a single rib, is a rare disease. Here we report a 73-year old male patient complaining of continuous chest wall pain around the right 5th rib shaft who underwent a wide excision of the rib tumor with surrounding connective tissue. He was diagnosed with solitary plasmacytoma and will undergo radiation therapy. We report this case with a review of the literature.

  • Solitary plasmacytoma (SP) is an uncommon form of plasma cell neoplasm occurring intraosseously or in soft tissue and presents as a single mass of monoclonal plasma cells. SP in the maxillary sinus is rare and can be misdiagnosed as other maxillary sinus tumors. The essential examinations in patients with the initial diagnosis of plasmacytoma are bone marrow biopsy, serum and urine electrophoresis, and kappa/lambda ratio (κ:λ ratio) to rule out multiple myeloma (MM). Herein, a rare case of SP in the maxillary sinus treated by surgery and localized radiation is reported. At the 10-year follow-up examination, local recurrence or disseminated development of MM were not evident.

  • Plasmacytoma is a rare malignant neoplasm in the head and neck region and comprises approximately 3% of all plasma cell tumors. This lesion is a unifocal, monoclonal, neoplastic proliferation of plasma cells that usually arises within the bone. Infrequently, it is observed in soft tissue, in which case, the term extramedullary plasmacytoma is used. Approximately 80-90% of extramedullary plasmacytomas involve the mucos-Associated-Lymphoid Tissue of the upper airways with 75% of these involving the nasal and paranasal regions. The plasmacytoma is usually detected in adult males, with an average age at diagnosis of 55 years. The male-to-female ratio is 3:1.Radiographically, the lesion may be seen as a well-defined, unilocularradioluceny with no evidence of a sclerotic border. Some investigators believe that this lesion represents the least aggressive part of the spectrum of plasma cell neoplasms that extend to multiple myeloma.Therefore, plasma cytoma is believed to have clinical importance. We report a case of extramedullary plasmacytoma in the right maxillary sinus of a 59-year-old male with review of the relevant literature.

  • Background: A moderate dose of radiation is the recommended treatment for solitary plasmacytoma (SP), but there is controversy over the role of surgery. Our study aimed at comparing different treatment modalities in the management of SP. Materials and Methods: Data from 38 consecutive patients with solitary plasmacytoma, including 16 with bone plasmacytoma and 22 with extramedullary plasmacytoma, were retrospectively reviewed. 15 patients received radiotherapy alone; 11 received surgery alone, and 12 received both. The median radiation dose was 50Gy. All operations were performed as radical resections. Local progression-free survival (LPFS), multiple myeloma-free survival (MMFS), progression-free survival (PFS) and overall survival (OS) were calculated and outcomes of different therapies were compared. Results: The median follow-up time was 55 months. 5-year LPFS, MMFS, PFS and OS were 87.0%, 80.9%, 69.8% and 87.4%, respectively. Univariate analysis revealed, compared with surgery alone, radiotherapy alone was associated with significantly higher 5-year LPFS (100% vs 69.3%, p=0.016), MMFS (100% vs 51.4%, p=0.006), PFS (100% vs 33.7%, p=0.0004) and OS (100% vs 70%, p=0.041). Conclusions: Radiotherapy alone can be considered as a more effective treatment for SP over surgery. Whether a combination of radiotherapy and surgery improves outcomes requires further study.

  • Purpose: To identify the clinical usefulness of serum M protein and to establish a rationale for regular follow-up with serum protein electrophoresis in solitary plasmacytoma. Materials and Methods: Sixty-nine patients with solitary plasmacytoma and solitary plasmacytoma with minimal marrow involvement according to the International Myeloma Working Group criteria were retrospectively reviewed. Results: At a median follow-up of 6.2 years, 5-year local control (LC), 5-year multiple myeloma-free survival (MMFS), 5-year failure-free survival (FFS), and 5-year overall survival (OS) were 82.6%, 44.1%, 41.8%, and 85.1%, respectively. Among the patients whose initial serum M protein was present or not evaluated, 37.3% of patients showed disappearance of serum M protein after various treatment. MMFS of these patients were comparable to non-secretory plasmacytoma with undetectable levels of M protein, and significantly better than patients with persistent M protein. Increase of serum M protein ≥0.1 g/dL was most predictive of treatment failure with area under the curve of 0.731. Conclusion: Patients who eventually showed persistence of serum M protein after treatment showed worse MMFS and FFS compared to those whose serum M protein disappeared or who had initially non-secretory disease. The increase of serum M protein level ≥0.1 g/dL from current nadir was predictive of treatment failure. Therefore, regular follow-up with serum M protein is highly recommended especially unless the patient had initially non-secretory disease.

  • Plasma cell neoplasms are generally categorized into four groups; multiple myeloma(MM), solitary plasmacytoma of the bone(SPB), plasma cell leukemias, and extramedullary plasmacytomas(EMP). These tumors may be further described as localized or diffuse in presentation. Localized plasma cell neoplasms are rare occurrences and include solitary plasmacytomas of the skeletal system, which account for 2-5% of all plasma cell neoplasms and extramedullary plasmacytomas of the soft tissue, which account for approximately 3% of all such neoplasms. A plasmacytoma is defined as any discrete, most likely solitary mass of neoplastic plasma cells either in the bone marrow or in various soft tissue sites. Diffuse lesions include the other two groups, multiple myeloma and plasma cell leukemia. The relationship between these processes has not yet been definitively characterized, but there appears to be a continuum in which both SPB and EMP often progress to MM. The patient was referred who had continuous deep throbbing bone pain and swelling on the left posterior gingival area of the mandible after extraction of the first and second molar. The result of intraoperative excisional biopsy of the lesion was confirmed as a plasmacytoma. And it revealed systemic multiple myeloma through the further diagnostic work-up. It is worth to report because of a rare case of multiple myeloma found in oral cavity as a form of plasmacytoma.

  • Extramedullary plasmacytoma (EMP) is a rare disorder that typically occurs in the upper airway. Although the condition rarely arises in the lungs, a few cases have been reported. Here, we report a case of pulmonary plasmacytoma in 66-year-old man, who had been treated with VAD (vincrestine, adriamycin, dexamethasone) chemotherapy for multiple myeloma. The patient had been declared clear of multiple myeloma after 4 cycles of chemotherapy. Three months later, the patient had multiple masses visible on computed tomography (CT) and on positron emission tomography-computed tomography (PET-CT) with hot uptake. Subsequent studies using CT-guided needle biopsy and immunohistochemical stain showed pulmonary plasmacytoma. Bone marrow biopsy, serum, and urine M protein tests were repeated, showing no evidence of multiple myeloma. Pulmonary plasmacytomas, as extramedullary plasmacytomas, were considered an isolated manifestation of multiple myeloma recurrence. We treated the patient with concurrent chemoradiotherapy and the pulmonary plasmacytomas regressed dramatically.
