Tumor epifýzy. V užším smyslu tumor vycházející z buněk epifýzy, tj. pinealocytom nebo pinealoblastom. Tumory epifýzy jsou vzácné, relativně nejčastější jsou různé druhy teratomu. Klinicky se mohou projevit hydrocefalem nebo Parinaudovým syndromem, mohou být i endokrinní příznaky. (cit. Velký lékařský slovník online, 2016 http://lekarske.slovniky.cz)

Neoplasms which originate from pineal parenchymal cells that tend to enlarge the gland and be locally invasive. The two major forms are pineocytoma and the more malignant pineoblastoma. Pineocytomas have moderate cellularity and tend to form rosette patterns. Pineoblastomas are highly cellular tumors containing small, poorly differentiated cells. These tumors occasionally seed the neuroaxis or cause obstructive HYDROCEPHALUS or Parinaud's syndrome. GERMINOMA; CARCINOMA, EMBRYONAL; GLIOMA; and other neoplasms may arise in the pineal region with germinoma being the most common pineal region tumor.
