Figure 2: (A) Photomicrograph of cytological specimens demonstrate foci of spindle cells in the background of normal intestinal epithelium (Diff-Quick, 200x). (B) Repeat aspirates demonstrate foci of spindle-to-epithelioid cells (Diff-Quick, 400x). (C) Photomicrograph of the resected specimen reveals cyst wall adjacent to the pancreas, which has evidence of fibrosis and chronic pancreatitis (H&E, 20x). (D and E) Photomicrographs of the resected specimen reveal a cystic mass adjacent to normal duodenal mucosa (H&E, 20x). (F) Photomicrographs of myoid spindle cell (e.g., stromal) proliferation at the lower portion of the image, which is most compatible with myofibroblasts and fibroblasts, as well as focal areas containing hemosiderin-laden macrophages noted (H&E, 200x).
