          Abstract

          Extramedullary plasmacytoma and solitary plasmacytoma are localized neoplasms. Solitary plasmacytoma of bone consists about 4% of malignant plasma cell tumors. A plasmacytoma involving the frontal bone is unusual, and a limited number of cases have been reported. We present a rare case of a solitary plasmacytoma of the frontal bone manifesting as a forehead lump.

          Intracranial involvement in plasmacytomas and multiple myeloma: a pictorial essay.

          Carmine Muccio, Lucia Monti, Alessandro Gozzetti … (2008)
          The purpose of this pictorial essay is to increase awareness of the clinical presentation, neuroradiological findings, treatment options, and neuroradiological follow-up of plasmacytomas and multiple myeloma with intracranial growth. This pictorial essay reviews the clinical features and neuroradiological findings in seven patients (four women, three men; age range at diagnosis 62-82 years) followed in two institutions. Six patients, one with IgG-kappa plasmacytoma, and five with IgG-kappa (n = 3), IgG-lambda (n = 1), and nonsecretory (n = 1) multiple myeloma, had been seen over a period of 9 years in one institution, and the other patient with IgG-kappa plasmacytoma had been seen over a period of 3.5 years in the other. Intracranial involvement is rare, most frequently resulting from osseous lesions in the cranial vault, skull base, nose, or paranasal sinuses. Primary dural or leptomeningeal involvement is rarer. Some typical findings of a dural and/or osseous plasmacytoma include iso- to hyperdensity on CT scan, T1 equal to high signal intensity and T2 markedly hypointense signal on MRI, and high vascularity possibly documented on intraarterial digital subtraction angiography. However, the neuroradiological findings generally lack specificity, since they are generally no different from those of meningioma, metastasis, lymphoma, dural sarcoma, plasma cell granuloma, infectious meningitis, and leptomeningeal carcinomatosis. The spectrum of clinical and neuroradiological evaluation shows that intracranial involvement from plasmacytoma and multiple myeloma must be taken into account in the differential diagnosis of cranial osseous and meningeal disease.

            Management of intracranial plasmacytoma.

            R D Bindal, H Loveren, Michael R. Sawaya (1995)
            The authors report on a study of eight cases of intracranial plasmacytoma to identify the risk of progression to multiple myeloma and suggest the treatment required for cure of solitary lesions. The diagnosis of multiple myeloma or myelomatous changes was made in the immediate postoperative period in four patients (50%), two of whom had skull base lesions. Of the four remaining patients, three were treated with complete surgical resection and radiation therapy and had no recurrence of plasmacytoma or progression to multiple myeloma during mean follow up of 12 years (range 2-25 years); one patient underwent subtotal surgical resection and had recurrence of the tumor despite radiation therapy. It is concluded that multiple myeloma is unlikely to develop during the long term in patients with intracranial plasmacytoma who do not develop multiple myeloma or myelomatous changes in the early postoperative period. However, lesions that infiltrate the skull base are not likely to be solitary, and patients who harbor these neoplasms should undergo complete evaluation and close follow-up review to exclude multiple myeloma. A recurrence of solitary intracranial plasmacytoma is possible with subtotal surgical resection despite radiation therapy. Definitive treatment should consist of complete surgical resection with adjuvant radiation therapy.

              Solitary plasmacytoma of bone vs. extramedullary plasmacytoma and their relationship to multiple myeloma.

              Michael Lindberg, Elizabeth Corwin (1979)
              Solitary plasmacytoma of bone (SPB) and extramedullary plasmacytoma (EMPC) are unusual solitary tumors of plasma cell origin. The clinical differences between these tumors and multiple myeloma are the subject of continued study. This review examines the radiotherapy experience at M. D. Anderson Hospital. Between 1948 and 1977, 12 patients with SPB and 12 patients with EMPC were treated with radiotherapy. Radiotherapeutic doses were most often (22/24) greater than 4,000 rads, at 200 rads per day. In order to qualify as solitary plasmacytoma a disease-free interval of 3 years was required. In the group of SPB, 5 patients of 9 were alive with no evidence of disease (NED) at 3 years, 4 of 5 at 5 years, and none of 4 at 10 years. In the EMPC group, 8 patients of 11 were NED at 3 and 5 years, and 6 of 9 at 10 years. Six patients with SPB developed multiple myeloma compared with only two with EMPC. The results confirm the better prognosis of EMPC and support the theory that SPB and EMPC are two different entities.
