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).

Immunohistochemistry revealed that the tumor cells were positive for CD20, CD38, CD138 and lambda light chain and negative for CD3 and CD21 (Figure 1).
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).

CR until October 2022. CT and MRI brain images at each time point are shown in Figure 2.

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).
