Extrascleral extension in association with ciliochoroidal melanoma: ultrasound biomicroscopy with histopathological correlation.
METHODS
We present the case of a 71-year-old man with a melanoma arising from the ciliary body and extending into the choroid. Ultrasound biomicroscopy (UBM) revealed connection via an emissary canal to a subconjunctival nodule. Although evaluation for metastasis was negative at the time of diagnosis, multiple hepatic metastatic deposits were found 2 years post-enucleation.


CONCLUSIONS
It is crucial to identify the presence of scleral invasion and extrascleral extension for proper management planning in patients with choroidal melanomas. This case demonstrates that UBM is an accurate and useful tool for characterizing the morphologic pattern of scleral invasion of intraocular tumours.
