  • The prognosis of solitary plasmacytoma varies greatly, with some patients recovering after surgical removal or local fractional radiation therapy, and others progressing to multiple myeloma years later. Primary detection of progression to multiple myeloma is important in the treatment of solitary plasmacytoma. There have been several analyses of the risk factors involved in the early progression to multiple myeloma. We describe one case of solitary plasmacytoma of the lumbar vertebra that was treated with surgical decompression with stabilization and additional radiotherapy. The patient had no factors associated with rapid progression to multiple myeloma such as age, size, immunologic results, pathological findings, and serum free light chain ratio at the time of diagnosis. However, his condition progressed to multiple myeloma less than two months after the initial diagnosis of solitary plasmacytoma. We suggest that surgeons should be vigilant in watching for rapid progression to multiple myeloma even in case that the patient with solitary plasmacytoma has no risk factors for rapid progression to multiple myeloma.

  • Multiple myeloma is a lymphohematopoietic disorder leading to abnormal hemostasis and significant pathologic changes of skeletal system. It induces multiple circular or oval-shaped radiolucent lesions which are characterized by 'punched-out appearance'. The surrounding trabecular bone normally shows no significant sclerotic reaction. Multiple myeloma patients may visit dental clinics, without perception of the disease themselves, due to discomfort from edema of orofacial region, oral ulcers, tooth mobility, pain or gingival bleeding. Multiple myeloma is susceptible to various complications, including delayed hemostasis and infection, which could occur during routine dental treatment such as periodontal and surgical operation. For radiographic diagnosis of multiple myeloma, common radiologic features of this tumor could be visualized by panoramic radiographs in the dental clinics, and further medical examinations and treatment can be recommended as a result.

  • A case of nonsecretory multiple myeloma in a 66 year-old-woman is reported. At first, she complained severe neck pain and radiologic finding showed C2 pathologic fracture. She complained severe low back pain 4 month later and L1 compression fracture was found. The lumbar MRI showed a 1.4cm-sized round enhancing lesion in the body of T12. Bone marrow aspiration biopsy at L1 spine showed a few polymorphous and small nests of mononuclear cell. L1 lamina bone biopsy showed many abnormal plasma cells. Pathologic diagnosis was multiple myeloma. However, plasma electrophoresis and protein immunoelectrophoresis of serum and urine of patient were normal. So, it is a nonecretory multiple myeloma case and the incidence of nonsecretory multiple myeloma is known to about 1% of all multiple myeloma.

  • Background: Patients with refractory or relapsed multiple myeloma are considered to have a very poor prognosis, and new regimens are needed to improve this setting. Pomalidomide is a new immunomodulatory drug with high in vitro potency. Immunomodulatory drugs are hypothesized to act through multiple mechanisms. Here we performed a systemic analysis to evaluate pomalidomide-based chemotherapy (pomalidomide in combination with low-dose dexamethasone) as salvage treatment for patients with refractory and relapsed multiple myeloma. Methods: Clinical studies evaluating the efffectiveness of pomalidomide based regimens on response and safety for patients with refractory and relapsed multiple myeloma were identified using a predefined search strategy. Pooled response rate (RR) of treatment were calculated. Results: For pomalidomide based regimens, 4 clinical studies which including 291 patients with refractory and relapsed multiple myeloma were considered eligible for inclusion. Systemic analysis suggested that, in all patients, pooled RR was 41.2% (120/291). Major adverse effects were hematologic toxicity, including grade 1 or 2 anemia, leucopenia and thrombocytopenia with pomalidomide based treatment. No treatment related death occurred. Conclusion: This pooled analysis suggests that pomalidomide in combination with low-dose dexamethasone is active with good tolerability in treating patients with refractory or relapsed multiple myeloma.

  • Background: Patients with refractory or relapsed multiple myeloma are considered to have a very poor prognosis, and new regimens are needed to improve the outcome. Gemcitabine, a nucleoside antimetabolite, is an analog of deoxycytidine which mainly inhibits DNA synthesis through interfering with DNA chain elongation and depleting deoxynucleotide stores, resulting in gemcitabine-induced cell death. Here we performed a systemic analysis to evaluate gemcitabine based chemotherapy as salvage treatment for patients with refractory and relapsed multiple myeloma. Methods: Clinical studies evaluating the impact of gemcitabine based regimens on response and safety for patients with refractory and relapsed multiple myeloma were identified by using a predefined search strategy. Pooled response rate (RR) of treatment were calculated. Results: In gemcitabine based regimens, 3 clinical studies which including 57 patients with refractory and relapsed multiple myeloma were considered eligible for inclusion. Systemic analysis suggested that, in all patients, pooled RR was 15.7% (9/57) in gemcitabine based regimens. Major adverse effects were hematologic toxicity, including grade 3 or 4 anemia, leucopenia and thrombocytopenia i. No treatment related death occurred with gemcitabine based treatment. Conclusion: This systemic analysis suggests that gemcitabine based regimens are associated with mild activity with good tolerability in treating patients with refractory or relapsed multiple myeloma.

  • This review focuses on the clinical use of $^{18}F$-FDG PET to evaluate multiple myeloma. $^{18}F$-FDG PET is useful for diagnosis, staging of multiple myeloma and differential diagnosis of myeloma related disease such as monoclonal gammopathy of undetermined significance or plasmacytoma. For therapy response, $^{18}F$-FDG PET may be effective after chemotherapy for multiple myeloma and radiotherapy for 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.

  • Multiple myeloma, a multicentric hematological malignancy, is the most common primary tumor of the spine. As epidural myeloma causing spinal cord compression is a rare condition, its therapeutic approach and clinical results have been reported to be diverse, and no clear guidelines for therapeutic decision have been established. Three patients presented with progressive paraplegia and sensory disturbance. Image and serological studies revealed multiple myeloma and spinal cord compression caused by epidural myeloma. Emergency radiotherapy and steroid therapy were performed in all three cases. However, their clinical courses and results were distinctly different. Following review of our cases and the related literature, we suggest a systematic therapeutic approach for these patients to achieve better clinical results.

  • A case of multiple myeloma with massive pleural effusion is reported. A 53 year-old previous known multiple myeloma patient vistited our hospital complaining of cough with sputum. Radiologic study revealed multiple osteolytic bony lesions and left side pleural effusion. The effusion were bloody exudates containing numerous atypical plasma cells. The tumor cells showed pleomorphism, eccentric nuclei, prominent nucleoli, perinuclear halo, multincleation, and chromatin patterns of occasional cart-wheel appearance. The cytological examination of pleural fluid established the malignant nature of the effusion with multiple myeloma.
