Overview
Pineocytoma, also known as a pinealocytoma, is a benign, slowly growing pineal parenchymal tumor.[1]
Pathophysiology
- On gross pathology, pineocytoma is characterized by solid, sometimes with focal areas of cystic change, well-circumscribed mass with or without hemorrhage.[2]
- On microscopic histopathological analysis, pineocytoma is characterized by:[3]
- Cytologically benign cells (uniform size of nuclei, regular nuclear membrane, light chromatin)
- Pineocytomatous/neurocytic rosette, which is an irregular circular/flower-like arrangement of cells with a large meshwork of fibers (neuropil) at the centre
