The images are shown in Figure 1.
Partial pathological section of tumor. Histological images of (A) H&E staining of enlarged histiocytes admixed with other inflammatory cells; (B) some enlarged histiocytes were observed phagocytosing plasmacyte; and (C) S100 and (D) CD163 immunostaining was positive in larger histiocytes.

Figure 2 shows the treatment process of the patient's tumor.
MRI and CT images of patients. Radiographic findings. Initial MRI brain sagittal cuts and T2-weighted sequences showing that the lesion did not have central nervous system involvement (A, B). There was abundant blood supply from the scalp (white arrow). Initial CT brain bone window along the sagittal (C) and coronal (D) views showing the potential lytic abnormality and the low density of the lesion. No obvious calcification of the lesion was found.
