Purpose:
To report the clinical, funduscopic, and echographic features of a choroidal metastatic tumor from a clear cell renal cell carcinoma presenting with intralesional cavitation.
Case Report:
An 81-year-old man with history of clear cell renal cell carcinoma presented with blurred vision. A clinical examination including standardized ultrasound was performed, which revealed a choroidal mass with cystic-like cavitation. The patient underwent brachytherapy with regression of the tumor.
Conclusions:
We report the features of a cavitary choroidal metastasis from clear cell renal cell carcinoma. Occurrence of features usually associated with uveal melanoma in a patient with a metastatic choroidal tumor may lead to misdiagnosis.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
