Plasma cell tumors are a heterogeneous group of neoplasms that includes multiple and isolated plasmacytomas and other immunoproliferative diseases. An extremely uncommon form of the disease are solitary extramedullary plasmacytomas (SEPs) of the central nervous system (CNS) which account for less than 1% of all malignant tumors and about 14% of hematological malignancies. A 37-year-old man came to the casualty department due to generalized seizures and a several-week history of a numbness of the left shoulder and left upper limb. Apart from severe obesity (weight 140 kg), he was otherwise healthy. Computed tomography (CT) of the head revealed a contrast-enhanced mass of 2.5 cm in diameter with surrounding edema in the right hemisphere. The patient was administered an anti-edema treatment and a control CT revealed a contrast-enhancing mass with dimensions of 37mm x 32 mm x 36 mm surrounded by extensive edema (Fig. 1 A) which strongly suggested glioblastoma multiforme (GBM). Due to the radiological picture and the lack of response to the anti-edematous treatment the patient was referred to the urgent surgery (radical resection of the tumor) without any other preliminary diagnostics (MRI or biopsy). Surprisingly, the histopathological examination of the surgical specimen revealed the features of plasmacytoma showing immunoreactivity for CD138 (Fig. 1 B), CD79A, CD3, GFAP, Ki67, vimentin, and CD10 and no reactivity for CD20, BCL6 and CD31. The bone marrow biopsy, bone scintigraphy as well as blood (calcium, b2-microglobulin, albumin, M-protein) and urine (M-protein) tests did not show any pathology. Three months after the resection a control magnetic resonance imaging (MRI) of the head showed a 23 mm x 16 mm x 21 mm tumor with an irregular marginal contrast enhancement corresponding to either post-operative changes or a residual/recurrent mass (Fig. 1 C). The positron emission tomography with 2-deoxy-2-[fluorine-18]-fluoro-D-glucose integrated with the computed tomography (18F-FDG PET/CT) did not reveal any other CNS pathology except of an enhanced glucose uptake (SUV 1.5) around the mass which indicated post-operative changes (Fig. 1 D). The patient was scheduled for radiotherapy to the volume of the post-operative pathological mass (contrast enhanced on neurologia i neurochirurgia polska 52 (2018) 543–545
