What is a HAMARTOMA?
benign, focal malformation that resembles a neoplasm in the tissue of its origin.
This is not a malignant tumor, and it grows at the same rate as the surrounding tissues.
It is composed of tissue elements normally found at that site, but which are growing in a disorganized mass.
What is a CHORISTOMA?
Nodules of organ parenchyma in another organ
E.g. normal (non-neoplastic) pancreas nodule in stomach
