This case report details a rare cavitary choroidal melanoma, an amelanotic tumor with internal cavities. This finding expands the differential diagnosis for intraocular cavitary lesions.

Area of Science:

  • Ophthalmology
  • Oncology
  • Pathology

Background:

  • Intraocular tumors can present with varied imaging characteristics.
  • Cavitary lesions within the eye are uncommon and typically associated with the ciliary body.

Observation:

  • A 38-year-old woman presented with an amelanotic tumor in the posterior choroid.
  • Diagnostic imaging, including ultrasonography, MRI, and CT, revealed intratumoral cavitations.
  • Enucleation allowed for detailed histopathologic examination.

Findings:

  • Histopathology confirmed a choroidal melanoma of the spindle cell type.
  • The tumor exhibited distinct intratumoral cavitations lined by flattened tumor cells.
  • Systemic and extraocular extension studies were negative, indicating localized disease.

Implications:

  • This case highlights uveal melanoma as a consideration in the differential diagnosis of choroidal cavitary lesions.
  • It represents a rare clinicopathologic correlation of cavitary choroidal melanoma.
  • Understanding this presentation aids in accurate diagnosis and management of rare ocular tumors.
