Photographs of a patient with schwannoma treated with partial lamellar sclerouvectomy (Case 2). (a). Slit-lamp biomicroscopy revealed a dark brown mass behind the iris occupying 9:00–2:00 o’clock (arrow) and dense cataract. (b). Ultrasound biomicroscopy revealed a middle-echoic mass in ciliary body. (c). Histopathologically, the tumor was composed of spindle cells in a fascicular arrangement (Antoni A pattern) and interspersed eosinophilic fibrillary cytoplasmic processes, forming Verocay bodies. (magnification: 400×, hematoxylin-eosin (H&E) stain). (d). Anterior segment photograph taken 10 days after partial lamellar sclerouvectomy showed superior iridectomy after tumor resection. (e). A photograph from the surgical video showed local resection of the tumor through a limbal-based scleral fap (arrow). (f-h). Immunohistochemical staining was positive for S-100 (f) and CD57 (g). Ki67 was about 5%(h)
