Overview
- Pineal embryonal carcinoma is a relatively rare malignant neoplasm and accounts for a small prportion of all intracranial germ cell tumors. It is an aggressive tumor and has a propensity to metastasise systemically. A component of embryonal carcinoma is often found in mixed germ-cell tumours, in which case it usually the most aggressive component, and dictates prognosis. Pure pineal embryonal carcinoma tumors do not secrete β-HCG or AFP.[1]
- On microscopic histopathological analysis, pineal embryonal carcinoma is characterized by poorly differentiated, pleomorphic cells in cords, sheets, or papillary formation.
