Histopathologic Finding of Both Gastric and Respiratory Epithelia in a Lingual Foregut Cyst

Figure 2

Histology. (a) Transition from respiratory-type ciliated pseudostratified columnar epithelium to gastric type epithelium (arrow). Hematoxylin and eosin, magnification at 400x. (b) The predominant epithelium of the cyst lining is respiratory-type ciliated pseudostratified columnar epithelium. Note the abundance of skeletal muscle with obvious cross striations in the cyst wall (arrows). Seromucinous glands are also present in the cyst wall (bottom right). Hematoxylin and eosin, magnification at 200x. (c) Alcian blue stain highlights the gastric epithelium while the adjacent respiratory-type epithelium is for the most part negative. Magnification at 200x.
