Intraoperative consultation of brain tumor fragments

Grossing

 
Resected fragments of a brain tumor, and in this case the very dark appearance supports a diagnosis of metastatic pigment-forming melanoma.

Measure the size of the specimen in 3 dimensions.

Squash prep

Remove a drop-size sample, place it on a glass-slide, then gently smear it out with another glass slide, followed by applying a fixative solution and staining with H&E.

Evaluation

The most common primary brain tumors are:[1]

  • Gliomas[2] (50.4%)
  • Meningiomas[2] (20.8%)
  • Pituitary adenomas[2] (15%)
  • Nerve sheath tumors (10%)

Also look into the patient's history for past cancers that may have metastasized to the brain.
