Abstract:
A 20-year-old white man demonstrated a 2-3 mm in diameter ball like, grey white vascularized tumor at 12h in the iris stroma adjacent to the sphincter pupillae OD. The tumor was excised by sector iridectomy. Light microscopically the tumor consisted of densely packed spindle-shaped cells with oval nuclei with granular eosinophilic cytoplasm. Electronmicroscopically numerous 9nm-filaments in parallel configuration were found, fusiform dense formations, basal membranes and pinocytotic vesicles. Positive immunohistochemical reaction for Actin, Desmin and Vimentin, negative for S100.
