Ciliary body adenoma of non-pigmented epithelium.
Adenomas of the non-pigmented epithelium of the ciliary body are rare neoplasms and most of the studies are in the form of case reports. There are only 27 documented cases of acquired neoplasm of the non-pigmented ciliary epithelium (NPCE) reported in the English literature. In most reports, there was a clinical suspicion of melanoma and the diagnosis of NPCE adenoma was made on histopathologic...

CASE REPORT We report the clinical features and surgery of a patient with an adenoma of the non-pigmented ciliary epithelium. The adenoma measured 5 × 7 mm. The patient underwent radical ocular surgery consisting of partial iridocyclectomy associated to lamellar sclerouvectomy. DISCUSSION Adenomas of ciliary body can mimic clinically amelanotic melanomas. We present details of the patient's m...
متن کاملAdenoma of the non-pigmented epithelium of the ciliary body with smooth muscle differentiation: a unique case report
Adenoma of the non-pigmented epithelium of the ciliary body (ANPCE) is a relatively uncommon lesion usually presenting in the non-pigmented epithelium of the ciliary body, which belongs to the neuroectodermal origin. Histologically, this tumor consisted of sheets, cords, and tubules occasionally forming glandular configurations. The cells of the tumor had abundant eosinophilic cytoplasm with ro...
متن کاملRenin-angiotensin system expression and secretory function in cultured human ciliary body non-pigmented epithelium.
BACKGROUND Renin-angiotensin system (RAS) components have been identified in human ciliary body and aqueous humour, pointing to a role for the RAS in the regulation of aqueous humour dynamics. Here, the authors examine the functional expression of a RAS and the effects of angiotensin II (AII) on a signal transduction pathway and ion secretion mechanism in cultured human ciliary body non-pigment...
