Intraocular lacrimal gland choristoma diagnosed by fine-needle aspiration biopsy.

PURPOSE: To describe an intraocular lacrimal gland choristoma confirmed with fine-needle aspiration biopsy in a child. METHODS: Case report. RESULTS: A 6-year-old Asian girl developed a pink, vascularized, cerebriform mass with marked corectopia in the inferonasal iris of the left eye. The differential diagnosis included juvenile xanthogranuloma, nevus, melanoma, medulloepithelioma, lacrimal gland choristoma, and atypical retinoblastoma. Fluorescein angiography was suggestive of a noninflammatory, nonleaking solid mass. Fine-needle aspiration biopsy showed benign epithelial cells consistent with lacrimal tissue. CONCLUSION: Lacrimal gland choristoma shows notable clinical features and fine-needle aspiration biopsy can be confirmatory.
