purpose : to describe the case of a 21-year-old patient with uveal effusion with no microphthalmia and any systemic disease that was treated with scleral window surgery and topical administration of mitomycin c (mmc) and zonulysis which was misdiagnose as a ring melanoma of cilliary body appeared shortly after the operation case report : a uveal effusion was detected in the eye. partial-thickne...
AIMS To define a retinoinvasive phenotype of uveal melanoma based on an informative case and survey of literature. METHODS A 65-year-old woman developed a circumscribed mixed cell type melanoma of the ciliary body that was locally excised. After 6 years, secondary glaucoma evolved. Three years later a ring melanoma was diagnosed and the eye was enucleated. The histopathological material was a...
leiomyoma is a very rare intraocular tumor, which can occur in the iris, ciliary body and choroids. we report a case of choroidal leiomyoma in a 16-years old women whose left eye was enucleated because of clinical suspicion for melanoma. using conventional light microscopy tumor was interpreted as spindle cell tumor, most probably of neurogenic origin and after using immunohistochemical studies...
2 cases of diffuse malignant ring melanoma of the anterior uvea are presented. A correct clinical diagnosis led to enucleation in case 1, while in case 2, the eye was enucleated 2 years after anti-glaucomatous surgery.
Purpose The most common malignant intraocular tumors with a high mortality in adults are uveal melanomas. Uveal melanomas arise most frequently in the choroid or ciliary body (97%) and rarely in the iris (3%). Whereas conjunctival and posterior uveal (ciliary body and choroidal) melanomas have been studied in more detail genetically, little data exist regarding iris melanomas. Methods In our ...
BACKGROUND Ring melanoma of the ciliary body and iris is extremely rare and often has adverse histology. This tumour may cause raised intraocular pressure. METHODS A review of four cases of ring melanomas with insidious presentations seen in the ocular oncology service over a 12 month period. RESULTS All four patients presented with unilateral anterior segment abnormalities and refractory g...
PURPOSE To report a case of ciliary body melanoma that masqueraded as chronic uveitis. METHODS A patient experienced persistent unilateral panuveitis and elevated intraocular pressure. Inflammation and pressure worsened after cataract extraction and lens implantation. Diagnostic vitrectomy was non-revealing. RESULTS Repeat vitrectomy and lens implant removal revealed a ciliary body mass, su...
Intraocular lymphangiogenesis in malignant melanomas of the ciliary body with extraocular extension.
PURPOSE To analyze whether lymphatic vessels can invade the normally alymphatic eye (lymphangiogenesis) in patients with malignant melanoma of the ciliary body with extraocular extension and to correlate these findings with metastasis-free survival. METHODS Ten enucleated globes with the histopathologically and immunohistochemically (S-100, HMB-45, PNL-2, and Melan-A) confirmed diagnosis of m...
BACKGROUND Ciliary body location is an established prognostic factor for metastasis-related death from uveal melanoma. We evaluated alternative approaches for classifying this covariate when constructing predictive models of patient survival. METHODS AND DESIGN The analyses were based on a consecutive series of 1848 primary choroidal and/or ciliary body melanoma patients treated with proton b...
