Extramedullary Plasmacytoma Mimicking Pancreatic Cancer: An Unusual Presentation

Figure 2

MR cholangiopancreatography before VBD therapy. (a) and (b) show a tumor mass localized at the hepatic hilum without cleavage plane with the head of the pancreas and blood vessels of about 8.35 × 8.7 × 8.9 cm. ((c) and (d)) Hematoxylin and eosin stain. Original magnification ×100 and ×200. The myeloma cell size and nucleus are polymorphic. Many cells have large eccentric nuclei, prominent nucleoli, and abundant basophilic cytoplasm (i.e., nuclear and cytoplasmic maturation asynchrony). (e) The neoplastic cells are positive for CD138. (f) The ki67 labeling index exceeds 50%.
