Goal: To contribute to differential diagnosis of changes of the outer segment of the eye. Case report: A 43-years old woman with three weeks long history of fast growing painless focus in the nasal part of the sclera of the left eye, which caused, except of visible tubercle and moderate feeling pressure, no problems. It is an unusual localization of non-malignant disease of unknown etiology originating from the Tenon’s capsule. The literature quotes the same histological finding in different organs; the localization in the eye is rare. The author considers difficulties of the differential diagnosis in the unusual ocular diagnosis. Conclusion: The diagnosis was specified on the basis of the ocular and following histological findings. The treatment is surgical.
