Choristoblastoma

/ˌkɔːrɪstoʊblæˈstoʊmə/ noun

Definition

A rare tumor that develops from tissue derived from an ectopic (misplaced) germ layer, combining features of multiple tissue types.

Etymology

From Greek 'choristos' (separated), 'blastoma' (tumor from cell growth), creating a compound medical term. This pathology term emerged in 20th-century medical literature.

Kelly Says

A choristoblastoma is basically when your body accidentally includes tissue from the wrong developmental layer in a tumor—like your cells got confused about where they should be!
