Abstract:
We herein present a rare case of pineocytoma in a 23-year-old female exhibiting distinct histomorphological features. The tumor contained highly pleomorphic, often multinucleated giant cells in the background of otherwise benign pineocytomatous architecture, which at first led to an erroneous diagnosis of a high grade malignancy. However, the worrisome histological findings turned out to be constituents of a distinct subtype of pineocytoma previously described as pleomorphic variant of pineocytoma. Although it is rare, pathologists should be aware of this entity since the tumor takes on a benign clinical course like any other classic pineocytomas.
