Medical Knowledge, Practice Based Learning and Systems Based Practice
- Recognize that thyroid-derived lesions are commonly encountered as mediastinal masses
- Recognize the utility of radiologic studies in confirming continuity of the thyroid with the mass in question
- Realize that the FNA findings of thyroid lesions presenting as mediastinal masses are as expected, once their origin as thyroid-derived is recognized
- Appreciate the utility of Romanowsky-stained preparations to recognize colloid when the precise origin of a given mass is not yet determined
- Recognize the frequency of parathyroid lesions presenting as mediastinal masses, and their ability to cause clinical symptoms (hyperparathyroidism)
- Become familiar with the FNA findings of a parathyroid lesion, particularly the difficulty in differentiating the component cells from follicular cells of the thyroid, based on cytomorphology alone
