Abstract
Purpose: To report unusual vitelliform fundus findings in three cases of paraneoplastic retinopathy associated with metastasised cutaneous or uveal melanoma and in one case, a unique immunoreactivity response. Patients and Methods: Observational case series. The histories of three patients with MAR-like paraneoplastic retinopathy were reviewed. Electroretinography, Goldmann perimetry, fluorescein angiography, and in one case optical coherence tomography, immunohistochemistry and Western blotting were performed. Results: All patients revealed similar paraneoplastic vitelliform retinal abnormalities. Symptoms in two cases differed from the classical MAR syndrome. In one case, western blotting and immunohistochemistry demonstrated antibodies against 120-kDa, a soluble photoreceptor protein. No immunoreactivity to retinal bipolar cells was detected. Conclusion: The clinical, electrophysiological, and immunological findings in our patients suggest a melanoma associated para-neoplastic origin, like in MAR syndrome. However contrary to MAR syndrome, this paraneoplastic vitelliform retinopathy exhibits a peculiar fundus picture, consisting of serous macular detachment and nummular vitelliform lesions in the posterior pole. This could be an unusual presentation of MAR or a separate paraneoplastic entity.
