Atypical choroidal nevus in a subject with a germline PALB2 pathogenic variant.

ABSTRACT: Recent evidence suggests that PALB2 variants may increase risk for the development of uveal melanoma and uveal melanocytic neoplasms. Here we report a case of an atypical choroidal nevus in a patient with a personal history of cancer and pathogenic PALB2 germline variant. A 75-year-old white female presented with an elevated predominantly amelanotic choroidal lesion OS. On examination and ophthalmic imaging, the mass measured 8.8 mm × 6.5 mm × 1.5 mm. The mass showed predominantly medium to high reflectivity on diagnostic A-scan and acoustic hollowing on B-scan. OCT over the lesion showed no subretinal fluid. The patient has a personal history of breast cancer and gastric adenoma and a strong family history of cancer. The patient was found to have a pathogenic truncating variant in PALB2 (
