Figure 1. Histologic characteristics of acinic cell carcinomas of the breast.

Figure 1.

(A-B) Representative photomicrographs of hematoxylin and eosin (H&E)-stained acinic cell carcinomas of the breast (ACCs) from this study. (A-C) ACC1 displays an infiltrative growth (A) with microglandular features (B) and is composed of Paneth-like cells with coarse intracytoplasmic granules (C). (D-E) ACC12 displays a microglandular growth pattern (D) with cells featuring an amphophilic cytoplasm with fine granules (E). (F-H) ACC18 displays microglandular areas (F) composed of eosinophilic cells with coarse granules (G) and hypernephroid areas composed of clear cells (H). Scale bar, 200 μm (A, D), 50 μm (B, and E), 20 μm (C, G and H) and 100 μm (F).
