Benign melanocytic tumors of the ciliary body, including spindle-cell naevi, can be challenging to differentiate from malignant melanomas. Ultrasound biomicroscopy and clinical presentation may not be definitive, even with documented growth.

Area of Science:

  • Ophthalmology
  • Oncology
  • Pathology

Background:

  • Benign melanocytic tumors of the ciliary body are rare and can mimic malignant neoplasms.
  • Accurate diagnosis is crucial for appropriate management and prognosis.

Observation:

  • A case series of six patients with pigmented ciliary body tumors was analyzed.
  • Clinical examination, ultrasound biomicroscopy (UBM), and histopathology were utilized.
  • Three cases underwent iridocyclectomy due to documented growth.

Findings:

  • All six patients presented with pigmented iridociliary masses.
  • UBM revealed stromal masses in the pars plicata and/or pars plana, with cysts in three cases.
  • Histopathology confirmed ciliary body spindle-cell naevus in the three surgically treated cases.

Implications:

  • Clinical and UBM findings alone are insufficient to reliably differentiate benign ciliary body naevi from melanocytoma or melanoma.
  • Documented tumor growth does not exclude a benign diagnosis of ciliary body naevus.
  • Further advancements in diagnostic imaging and molecular markers may be needed for definitive preoperative diagnosis.
