Abstract: Rationale: Uveal tract schwannomas are extremely rare tumors that can mimic choroidal melanoma, which makes diagnosis and treatment tactics difficult. Despite the fact that this is a benign tumor, if untimely treatment is not provided, it can reach the degree of melanoma differentiation and have extraocular growth, which changes the vital prognosis. Objective: To present a clinical case of choroidal schwannoma, analyze the features of diagnosis and choice of treatment tactics. Methods: Diagnostics and examinations were performed at the State Budgetary Healthcare Institution of the Nizhny Novgorod Region “City Hospital No. 35 of the Sovetsky District” of Nizhny Novgorod and included: examination of the fundus under conditions of drug-induced mydriasis, B-scanning, histological and IHC studies of the enucleated eyeball. Results: According to the results of the morphological study, a rare tumor of the uveal tract, namely schwannoma, was obtained, which was subsequently confirmed by the performed IHC study. Conclusion: Despite the benign nature of the tumor, its tendency to imitate uveal melanoma and the peculiarities of the clinical course (a high percentage of relapses after non-radical surgical treatment, frequent extraocular growth, pain syndrome developing due to the size and inevitable loss of visual functions), enucleation is a relevant method of surgical treatment as a treatment tactic, since all organ-preserving interventions lead to continued tumor growth.
