Abstract

Purpose: Uveal ganglioneuroma is a rare tumor that usually occurs in association with neurofibromatosis type 1. Here, we present a rare case of a uveal ganglioneuroma leading to a diagnosis of the tumor predisposition condition Cowden syndrome. Procedures: A 5-year-old girl with unilateral refractory glaucoma secondary to diffuse iris and choroidal thickening developed a blind, painful eye. Enucleation was performed, and histopathology revealed infiltration of the entire uveal tract by neoplastic spindle cells containing admixed ganglion cells diagnostic of uveal ganglioneuroma. Targeted next-generation sequencing of 510 cancer-associated genes was performed on tumor tissue and peripheral blood. Results: A germline nonsense mutation in the PTEN gene was found, accompanied by loss of heterozygosity in the tumor. A diagnosis of Cowden syndrome was made, for which the family sought genetic counseling and initiated the recommended cancer screening. Conclusions: A novel association is found between uveal ganglioneuroma and Cowden syndrome, emphasizing the value of genetic tissue testing in managing patients with rare ocular tumors.
