"Literally, exophytic only refers to those lesions arising from the outer surface, however radiologists and pathologists use the term to include those lesions that arise deeper within the organ of origin but whose centre lies outside the organ. Others use a looser definition and include those lesions with their centres within the organ, but which protrude from the surface. Other radiologists for the latter lesions qualify the term and state "partially exophytic"."
"Another term gaining traction is mesophytic, meaning less than 50% protusion of the lesion outside the organ surface and was initially used when describing renal tumours 3. With the 50% threshold applied, a lesion protruding greater than 50% beyond the organ margin can be defined as exophytic, and one entirely within the organ parenchyma can be termed endophytic 3."

"Exophytic is derived from the Ancient Greek roots: εξω (exo) meaning 'outer' and φυτον (phuton) meaning 'plant'; in botany, the term exophyte refers to a parasite that grows on the outside of a plant 2."
