[Choroid neurilemmoma. Considerations for clinical differential diagnostics]

Area of Science:

• Ophthalmology
• Pathology
• Surgical Oncology

Background:

• Neurilemmomas are rare tumors arising from nerve sheath cells.
• Choroidal tumors pose significant diagnostic challenges, often mimicking other intraocular malignancies.
• Malignant melanoma is the most common primary intraocular malignancy, necessitating accurate differential diagnosis.

Observation:

• An extremely rare case of neurilemmoma originating in the choroid is presented.
• The clinical presentation made differentiation from malignant melanoma exceptionally difficult.
• Pre-operative diagnosis and non-surgical treatment were not feasible.

Findings:

• The definitive diagnosis of choroidal neurilemmoma was established solely through post-operative histological examination.
• The tumor's rarity and location contributed to the diagnostic ambiguity.
• Enucleation was the only clinically viable treatment option.

Implications:

• This case underscores the importance of histological confirmation for rare choroidal tumors.
• Accurate differential diagnosis is crucial for appropriate management of intraocular masses.
• Further research into diagnostic modalities for rare choroidal neoplasms is warranted.
