Definition
A very rare, low-grade neoplasm that arises from the posterior pituitary. It is composed of epithelioid and oncocytic cells forming sheets and fascicles. It shows histopathological features reminiscent of ependymomas, including perivascular pseudorosettes and true rosettes. There is no evidence of necrosis or increased mitotic activity. Despite the presence of ependymal histopathological features, these neoplasms probably are not related to ependymomas. Their prognosis is unknown.

Key figures
Each figure carries its unit, period and source; ranks link to "Why this rank?".
No registry-level ancestor: burden figures are published for the mutually exclusive top-level site groups only, and this entity does not descend from one. Global figures (IARC / GLOBOCAN) stay under license review and SEER awaits credentials.
