Yellow–white granulation-like tissue was seen in the sections, and the parenchyma was hard; B: Hematoxylin and eosin staining after surgery showed fibroblast proliferation and abundant plasma cell and lymphocyte infiltration in the stroma; C: Immunohistochemistry (400×) was positive for smooth muscle actin; D and E: Spindle cells (400×) were also positive for CD38 (D) and CD138 (E); F: Tumor cells showed a positive cytoplasmic reaction with ALK (400×).
