case_images: Special stains and immunohistochemical preparations show the following results: Positive trypsin, BCL-10, and beta-catenin (membranous) with weak and focal positivity for neuroendocrine markers (synaptophysin, chromogranin, and CD56), PAS-D highlighted intracytoplasmic zymogen granules, and CD10 was negative [Figure 3].
