[Sarcoid granuloma of the iris (clinical cases and state of the problem)].

Granulomatous lesion of the iris has varying etiology, but in the differential diagnostic it should often be considered by sarcoidosis and tuberculosis damage.
To describe a clinical case of sarcoid lesion of the iris and provide an analysis of literature devoted to this problem in the context of its polyetiology.
The article describes one case of sarcoid granuloma of the iris in a young patient with a relapsing course of the disease.
The presented clinical case demonstrates the need for differential diagnosis to clarify the causes of the disease and the possibility of recurrence involving appearance of a multifocal lesion. The article also reviews literature on this problem reflecting the polyetiological nature of granulomatous lesions of the iris, and argues the use of interventional diagnostic methods in the absence of extraocular pathology.
Analysis of the clinical case and literature clearly demonstrates the need for differential diagnosis of granulomatous lesions of the iris.
