This case study details a rare ciliary body schwannoma, a benign tumor. Diagnosis was confirmed through histopathology, immunohistochemistry, and electron microscopy, aiding differentiation from other intraocular neoplasms.

Area of Science:

  • Ophthalmology
  • Oncology
  • Pathology

Background:

  • Intraocular schwannomas are exceptionally rare benign peripheral nerve neoplasms.
  • Ciliary body schwannomas are particularly uncommon intraocular tumors.

Observation:

  • A 39-year-old woman presented with progressive vision loss and proptosis in her right eye over four years.
  • The affected eye exhibited exophthalmos and lateral deviation, with complete light perception loss.

Findings:

  • Histopathological examination revealed spindle cells with Antoni type A and B areas and Verocay bodies.
  • Immunohistochemistry confirmed S-100 and vimentin expression in tumor cells.
  • Electron microscopy identified Luse bodies, characteristic of schwannomas.

Implications:

  • Accurate diagnosis of ciliary body schwannoma is crucial for appropriate management.
  • Differentiating this benign neoplasm from other intraocular tumors is essential for patient outcomes.
