Figure 3 Biopsy images of acinar cell carcinoma. Microscopically, several clusters of nests, alveolar and papillary arrangement, fine nuclear chromatin, fine nucleoli, scattered cells, deviated nuclei, and extracellular particles are visible in the background suggestive of neoplastic lesions. A: Staining was positive for cytokeratin (original magnification 200); B: Staining was positive for epithelial membrane antigen 1 (original magnification 100); C: Staining was positive for hematoxylin and eosin (original magnification 100).
