Solitary plasmacytoma of the skull. A case report

Abstract

A case of solitary plasmacytoma of the skull is presented. The tumor was radically removed. There was no systemic involvement and the patient was not submitted to radiotherapy. Lytic lesions of the skull are discussed.

Solitary plasmacytoma of the calvarium: a review of clinical and prognostic features

“…As this tumor is highly radiosensitive, some authors [3,7,14,24] consider that it is best to give radiotherapy (50-60 Gy megavoltage therapy) after histological diagnosis of the tumor on the biopsy evidence. Others [1,2,15,16] argue that grossly total removal of the tumor not followed by radiotherapy affords long recurrence-free survival (range 15 months to 10 years). In group B, chemotherapyinduced a significant improvement of the symptoms in two of the five cases in which it was given.…”

Skull vault plasmacytoma mimicking parasagittal meningioma: “Mini-brain appearance”

“…Myeloma is a hematological malignancy that originates from plasma cells of bone marrow. [12] Plasma cell neoplasms can be classified into multiple myeloma, solitary plasmacytomas of bone, and extramedullary plasmacytomas. [12] While multiple myeloma is a systemic disease, solitary plasmacytoma and extramedullary plasmacytomas are focal forms of plasma cell neoplasms.…”

“…[1] Skull vault plasmacytomas are rare lesions comprising 0.7% of all plasmacytomas. [23] They can mimic meningiomas, osteogenic sarcomas, or metastatic carcinomas on radiologic imaging.…”

Bone mass of the calvarium

“…Plasmacytoma of the calvarium is very rare, accounting for the 0.7 % of all plasmacytomas [1][2][3][4][5]. The most common locations are the thoracic and lumbar spine (30-40 % of cases).…”

“…1 question) [1,6]. On computed tomography (CT), plasmacytoma presents as a lytic punched-out lesion with interspersed residual thickened bony trabeculae.…”
