Morphology
choristoma = chorist (opaque) = chorist + oma
This is a specialized medical formation (chorist- + -oma) whose elements are obscure to general learners, so the meaning cannot be reliably derived from the parts.
Etymology
Choristoma comes from Greek parts chorist- meaning 'separate' and -oma meaning 'tumor'. So a choristoma is a mass of normal tissue that has become 'separated' into the wrong place in the body, which is why it can look like a growth.
