| 11. | The embryonic remnants of Rathke s pouch may undergo neoplastic change called a craniopharyngioma.
|
| 12. | The causes are varied, and may be inflammatory, degenerative, or neoplastic.
|
| 13. | Tumors may be caused by conditions other than an overgrowth of neoplastic cells, however.
|
| 14. | Acquired Horner syndrome may result after trauma, neoplastic insult, or even vascular disease.
|
| 15. | EIN cells are already neoplastic, demonstrating a monoclonal growth pattern and clonally distributed mutations.
|
| 16. | PLK1 has also been linked to known pathways that are altered during the neoplastic transformation.
|
| 17. | Nuclear atypia can be seen in reactive changes, pre-neoplastic changes and malignancy.
|
| 18. | The unique disease principle was first described in neoplastic diseases as the unique tumor principle.
|
| 19. | Likewise, epigenetic alterations present in tumors may have occurred in pre-neoplastic field defects.
|
| 20. | In most cases of malignant disease complicated by effusion, neoplastic cells can be easily recognized.
