Overview

  • Pineal choriocarcinoma is a relatively rare, malignant, highly vascular neoplasm and accounts for a small proportion of all intracranial germ cell tumors. It is an aggressive tumor and has a propensity to metastasise systemically. Pure pineal choriocarcinoma tumors secrete β-HCG.[1]
  • On microscopic histopathological analysis, pineal choriocarcinoma is characterized by presence of intimately related syncytiotrophoblasts and cytotrophoblasts without formation of definite placental type villi. Syncytiotrophoblasts are large multi-nucleated cells with eosinophilic cytoplasm. They often surround the cytotrophoblasts, reminiscent of their normal anatomical relationship in chorionic villi. Cytotrophoblasts are polyhedral, mononuclear cells with hyperchromatic nuclei and a clear or pale cytoplasm.[2]
  • Pineal choriocarcinoma accounts for 5% of all pineal masses and 10% of all intracranial germ cell tumors.[1]
  • The peak age at diagnosis for pineal choriocarcinoma is 20-30 years.
  • Common complications of pineal choriocarcinoma include:[3][4]
  • Laboratory findings consistent with the diagnosis of pineal choriocarcinoma include abnormal CSF analysis, demonstrating xanthochromia.
