Clinically stationary choroidal melanoma with extraocular extension

Area of Science:

• Ophthalmology
• Oncology

Background:

• Malignant melanoma of the choroid can present diagnostic challenges.
• Initial misdiagnosis as disciform macular degeneration can delay appropriate management.

Observation:

• A case of choroidal melanoma was monitored for three years.
• The tumor showed no significant lateral or vertical growth during this period.

Findings:

• An erroneous diagnosis of disciform macular degeneration was initially made.
• Significant extrascleral extension of the choroidal melanoma was detected later.
• Radioactive phosphorus uptake tests aided in identifying the extrascleral extension.

Implications:

• This case highlights the importance of considering rare diagnoses even with atypical presentations.
• Delayed diagnosis of choroidal melanoma can lead to advanced disease and complications.
• Accurate diagnostic tools and vigilance are crucial for effective management of ocular tumors.
