case_images: Immunohitsochemical (IHC) analysis of the morphology of left frontal mass in case 2. A markedly proliferation of abnormal plasma cells was observed by H&E staining (x 400) (A). Abnormal plasma cells were positive for CD38 and CD138 (IHC staining x 400) (B, C). Abnormal plasma cells expressed lambda (IHC staining x 400) (D).

case_images: Immunohistochemistry revealed that the tumor cells were positive for CD20, CD38, CD138 and lambda light chain and negative for CD3 and CD21 (Figure 1).
case_images: Computer tomography (CT) and magnetic resonance imaging (MRI) brain images from a female patient present with left frontal mass. CT brain image (A) and enhanced MRI brain image (B) at diagnosis showed a mass of 3.2 x 4.8 cm in left frontal lobe; CT brain image after resection of left frontal lobe mass, the mass disappeared (C); CT brain image before autologous hematopoietic stem cell transplantation (auto-HSCT), no mass in left frontal lobe (D).

case_images: Computer tomography (CT) and magnetic resonance imaging (MRI) brain images from a female patient present with bilateral frontal mass. Enhanced MRI brain image (A) and CT brain image (B) at diagnosis showed a mass of 5.3 x 7.0 cm in bilateral frontal lobe; CT brain image after resection of bilateral frontal lobe mass, the mass disappeared (C); MRI brain image before autologous hematopoietic stem cell transplantation (auto-HSCT), no mass in bilateral frontal lobe (D).
