The histomorphological spectrum of pineal parenchymal tumors (PPT) is diverse and not as clearly defined as other brain tumors due to their rarity. At one end of this spectrum lie pineocytomas, which are well-differentiated tumors that retain the morphological and immunohistochemical features of pineal parenchymal cells. A rare, but distinct subtype of pineocytoma has been previously described as pleomorphic variant of pineocytoma with gangliocytic differentiation containing giant cells with bizarre shaped nuclei which can easily be overdiagnosed as a high-grade malignancy. We describe a case report of a 58 years patient who had pineal parenchymal tumor with cellular features of a pineocytoma along with pleomorphic cells.
