Abstract Background Bilateral diffuse uveal melanocytic proliferation (BDUMP) is an extremely rare paraneoplastic syndrome, with most cases reported as secondary to female urogenital and male lung malignancies. We reported this case of BDUMP patient whose primary malignancy was gastric adenocarcinoma verified with gastroscopy and subsequent pathological test. Case presentation A patient complaining blurred vision was suspected of bilateral diffuse uveal melanocytic proliferation (BDUMP), due to bilateral round oval patches at the posterior pole and cardinal signs in retinal angiography. Malignancy screening was suggested, and pathological report from gastroscopy confirmed the primary lesion as gastric adenocarcinoma. The patient chose palliative care due to late stage and unresectable nature of the malignancy. Conclusions Identifying BDUMP warrants further investigation of a primary malignancy. Our case provided evidence for the link between gastric adenocarcinoma and BDUMP.
