Figures 1–Figures 1–9 were inadvertently printed as one column when they should have been the width of two columns. Allen Press apologizes for this error.

Fig. 1.

Head; cat No. 1. MRI of an oval-shaped mass at the cranial base (arrows). The white opaque mass is located in the area of the hypothalamus to the optic chiasm.

Fig. 2.

Intracranial tumor mass; cat No. 1. There is a white solid mass on the skull base. Brain was removed. Bar = 1.5 cm.

Fig. 3.

Intracranial tumor mass; cat No. 1. The tumor is composed of small multiangular- or spindle-shaped neoplastic cells proliferating in a solid mass. There are large cysts lined with flat cells. HE. Bar = 700 µm.

Fig. 4.

Intracranial tumor mass; cat No. 1. The small acinus part. Relatively large cells with pale cytoplasm compose small acini. HE. Bar = 12 µm.

Fig. 5.

Intracranial tumor mass; cat No. 1. The duct part. Small cuboidal cells compose ducts. HE. Bar = 25 µm.

Fig. 6.

Intracranial tumor mass; cat No. 1. The pavement part. Large multiangular-shaped cells proliferate in a pavement pattern. HE. Bar = 50 µm.

Fig. 7.

Intracranial tumor mass; cat No. 1. The tumor cells are positive for keratin. Immunostain counterstained with hematoxylin. Bar = 50 µm.

Fig. 8.

Intracranial tumor mass; cat No. 1. Electron microscopy of a tumor cell. Note the microvilli at the free margin (small arrows), tonofilaments in the cytoplasm (large arrow) and desmosome-like structures (large arrowheads). The cell binds to the basement membrane by hemidesmosome-like structures (small arrowheads). Bar = 1.2 µm.

Fig. 9.

Intracranial tumor mass; cat No. 2. The tumor tissue is composed of small cuboidal anaplastic epithelial cells, often making ducts and small or large cysts. HE. Bar = 100 µm.
