Medical knowledge, practice based learning and systems based practice
  1. Recognize the incidence of CNS metastases in patients with solid tumors
  2. Recognize the most common primary tumors which may metastasize to the CNS
  3. Identify typical radiologic findings of metastatic lesions in the CNS
  4. Recognize typical cytomorphologic features of metastatic lesions and morphologic clues which may allow identification of the primary site (i.e. intracellular pigment in melanoma, vacuolated cytoplasm in renal cell carcinoma)
  5. Recognize the utility of immunohistochemical staining to confirm the diagnosis of metastases and aid in the determination of the primary site of malignancy
