(A, B, D, E) MRI scans showed a well-defined oval mass located in cervix, which destroyed the stroma (A). The mass showed slight hyperintensity on T2-weighted MR images (A, D) and isointensity on T1-weighted MR images (B, E). (C) The ADC map showed low ADCs. (F) Sagittal contrast-enhanced MR image showed mild to moderate heterogeneous enhancement of the lesion, presenting rim-enhancement.

The pelvic magnetic resonance imaging (MRI) scan found a well-defined oval mass of size 2.3x1.8x2.8 cm in the cervix, which destroyed the continuity of the cervical stroma (Figure 1A). D), and isointense on the T1-weighted images (Figures 1B, E). Decreased apparent diffusion coefficient (ADC) value were detected in the cervical lesion (Figure 1C). Post-contrast enhancement images showed mild to moderate heterogeneous enhancement and pronounced peripheral rim enhancement (Figure 1F).
Histological and immunohistochemical features of SEP. (A) Hematoxylin-eosin staining shows that the monoclonal well-differentiated plasma cells are diffusely distributed and consistent in size. (B-D) Immunohistochemical staining presented CD38(+), CD138(+), Kappa (+). [Original magnifications: (A, B) 200x; (C, D) 400x].

Immunohistochemical staining was positive with CD38, CD138, Kappa (Figure 2) and negative with Lambda.
