Unusual brain tumors with signet-ring cells were diagnosed as ependymoma using electron microscopy. This study details the light and electron microscopic features for accurate diagnosis.

Area of Science:

  • Neuropathology
  • Oncology
  • Electron Microscopy

Background:

  • Primary brain tumors can present with rare and challenging histopathological features.
  • Signet-ring cell morphology in brain tumors is uncommon and requires specialized diagnostic techniques.

Observation:

  • Two patients presented with primary brain tumors exhibiting abundant signet-ring cells.
  • Initial light microscopy was insufficient for definitive tumor classification.

Findings:

  • Electron microscopic examination was crucial for diagnosing these tumors as ependymoma.
  • The study details the distinct light and electron microscopic characteristics of these signet-ring cell ependymomas.

Implications:

  • Highlights the importance of electron microscopy in diagnosing rare brain tumors.
