Cerebral pleomorphic liposarcoma: Clinicopathologic findings.

We present a 62-year-old woman with an intraparenchymal mass involving the left frontoparietal lobes. Histologic examination demonstrated a mesenchymal neoplasm with a dense reticulin network and pleomorphic lipoblasts. Immunohistochemical stain for adipophilin highlighted intracytoplasmic vacuoles. MDM2 immunostain was negative. A diagnosis of pleomorphic liposarcoma was made. There was no evidence of an extracranial primary neoplasm by imaging or physical exam. Pleomorphic liposarcoma may rarely present as a solitary intracranial mass, an entity that must be entertained in the differential diagnosis of pleomorphic tumors involving the brain.
