Coexistence of cervical extramedullary plasmacytoma and squamous cell carcinoma: A case report

Figure 2 Pathology results of extramedullary plasmacytoma. A: Hematoxylin-eosin (HE) staining of extramedullary plasmacytoma. The tumor cells were diffusely distributed. Pathological spindle division and Russell body were observed; B: HE staining of cervical squamous cell carcinoma. Hyperplasia of epithelioid cell nests, infiltrating growth pathological fission, and intercellular Bridges were easily observed; C: Immunohistochemistry staining of Kappa, which was diffusely positive in Plasma tumor cells; D: Immunohistochemistry staining of Lambda, which was diffusely negative in Plasma tumor cells; E: Immunohistochemistry staining of CD38, which was diffusely positive in Plasma tumor cells; F: Immunohistochemistry staining of CD138, which was diffusely positive in Plasma tumor cells; G: Immunohistochemistry staining of p40, which was diffusely positive in cervical squamous cancer cells; H: Immunohistochemistry staining of CK5/6, which was diffusely positive in cervical squamous cancer cells.
