The development of changes in the iris, with unexpected histologic diagnoses, is described. One patient was found to be suffering from bilateral iris nodules, the unexpected manifestation of a Boeck's sarcoid which had not been diagnosed. In another case, the growth observed in the size of the tumor seemed to indicate malignancy, although histology showed it to be a benign leiomyoma with increasingly cystic changes. In the third case we suspected a metastasis of a bronchial carcinoma but histologic examination showed it to be a malignant melanoma. The various differential diagnostic considerations are discussed.
