Purpose:
Longitudinal evaluation of acute exudative polymorphous paraneoplastic vitelliform maculopathy (AEPPVM) following diagnosis and treatment of metastatic melanoma.
Methods:
Case report of a 47-year-old male with unknown primary metastatic melanoma and AEPPVM monitored before and during melanoma treatment using clinical exam, retinal imaging, and electroretinograms (ERG). Genetic testing and autoantibody panels were performed.
Results:
He presented within a month of metastatic melanoma diagnosis with numerous bilateral vitelliform lesions in the posterior pole, consistent with AEPPVM. Metastatic disease was treated with immunotherapy, radiosurgery, and radiation over 48 months. Maculopathy and metastatic disease improved and worsened in parallel. Genetic testing was negative for bestrophin-1. An autoantibody panel was positive for anti-recoverin and transducin-α.
Conclusion:
AEPPVM is an uncommon paraneoplastic retinopathy found in patients with metastatic malignancy. To our knowledge, this is the first report demonstrating a temporal association between metastatic disease activity and quantifiable changes in retinal imaging over a 4-year period.
