PURPOSE: To describe didactically the local, regional and systemic spread of choroidal melanoma.
PATIENTS AND METHODS: Two patients who had undergone primary enucleation for the management of choroidal melanoma in 2018 at the University Hospital of Nice were included. Extrascleral extension and invasion of the vortex veins were evaluated, as well as synchronous and metachronous metastases, based on our database.
RESULTS: Patient 1 was diagnosed with large choroidal melanoma with partial scleral invasion and vortex vein involvement. Cytogenetic analysis demonstrated a loss of chromosome 3, and a gain of chromosome 8q. Systemic work-up was unremarkable. Patient 2 was diagnosed with a large choroidal melanoma with extrascleral extension and vortex vein involvement. Cytogenetic analysis demonstrated a loss of chromosome 3 and a gain of chromosome 8q. Systemic work-up revealed several liver metastases. A total of 1762 patients were included in our database. Eighty-five patients (4.8 %) and 46 patients (2.6 %) experienced vortex vein invasion and extrascleral extension respectively. Patients with vortex vein invasion were diagnosed with synchronous and metachronous liver metastases in 1.2 % and 18.8 % respectively. Patients with extrascleral extension had synchronous and metachronous liver metastases in 6.5 % and 30.4 % respectively. The mean follow-up was 49.4 months (1-180).
CONCLUSION: Extrascleral extension and vortex vein invasion illustrate the local, regional and systemic spread of choroidal melanoma. The latter are often associated with genetically aggressive tumours associated with high metastatic risk.
