- medulloblastoma (the presence of Homer Wright rosettes in a posterior fossa tumor is nearly pathognomonic for medulloblastoma)
- primitive neuroectodermal tumors (PNETs)
- olfactory neuroblastoma
- pineoblastoma
History and etymology
Homer Wright rosettes are named after James Homer Wright (1869–1928), Massachusetts (USA), developer of the Wright stain 1.
