Mesectodermal leiomyoma of the ciliary body is a rare tumor originating from smooth muscle, having both muscular and neural differentiation.1 The first case was reported in 1977, and so far 24 cases have been reported.1 It should be considered in the differential diagnosis of an amelanotic melanoma, especially in young people. Herein, we report a case of mesectodermal iridociliary leiomyoma in a young man, showing the results of ultrasound biomicroscopy, 3-T magnetic resonance imaging, histology, and immunohistochemistry. The tumor was excised en bloc by a transscleral approach and later treated with ruthenium 106 plaque brachytherapy.
