cells are numerous cellular processes of variable width.
Some processes are quite narrow and have a regular,
often parallel alignment.

| Figure 5. Between the irregularly shaped and sized tumor
cells are numerous cellular processes of variable width. Some processes are quite narrow and have a regular, often parallel alignment. | Figure 6. Detail of an area in Figure 5 showing the numerous, elongated, narrow and often sinuously arranged cellular process often with a regular alignment (arrows). |

| Figure 7. Some of the cellular processes tend to partially encircle extracellular spaces and focally develop basal lamina (arrow). Many of the narrow cellular processes intricately interlock with each other or portions of the cytoplasm of the tumor cells. |
