Pancreatic Tail Schwannoma in a 44-Year-Old Male: A Case Report and Literature Review

Figure 2

Microscopic examination of the pancreatic tail tumor. (a) Tumor was composed of monomorphic spindle-shaped Schwann cells with poorly defined eosinophilic cytoplasm and pointed basophilic nuclei set in a collagenous stroma. Focal nuclear palisading is noted (H&E stain, magnification power: 10x). (b) Areas characteristic for Antoni B composed of Schwann cells with inconspicuous cytoplasm and nuclei suspended in myxoid matrix are identified. Scattered degenerated nuclei in a hyalinized stroma suggestive of ancient schwannoma were present. No mitosis or necrosis was noted (H&E stain, magnification power: 40x).
