Pathologists use the term exophytic to describe an abnormal growth that sticks out from the surface of a tissue. This pattern of growth can be seen when the tissue is examined under a microscope. Pathologists use the word exophytic to describe both benign (non-cancerous) growths and malignant tumours (cancers).
Exophytic is not a diagnosis by itself. It is a description of the changes seen under the microscope. The word exophytic should be considered together with the other information in your pathology report such as the types of cells in the growth and the size.
The opposite of exophytic is endophytic.
