case_images: (A-B) Hematoxylin and eosin (H&E) stained section showing sheets of myoepithelial cells and ductular structures lined with epithelial cells set in chondromyxoid stroma (H&E, A: x40; B: x100). (C) Adjacent to the lesion, normal laryngeal cartilage can be seen (H&E, x100).

case_images: Epithelial component consisted of relatively uniform-appearing cells arranged in tubules and small, nested aggregates (Figure 1).
case_images: Immunohistochemistry indicates that the myoepithelial cells cytoplasm is focally positive for S100 protein (A) and glial fibrillary acidic protein (GFAP) (B) (A: x100; B: x100).

case_images: Myoepithelial component was positive for p63, S100 protein (Figure 2A), and glial fibrillary acidic protein (GFAP) (Figure 2B); and focally positive smooth muscle actin (SMA).
