S Kaliki, C L Shields
Although it is a relatively rare disease, primarily found in the Caucasian population, uveal melanoma is the most common primary intraocular tumor in adults with a mean age-adjusted incidence of 5.1 cases per million per year. Tumors are located either in iris (4%), ciliary body (6%), or choroid (90%). The host susceptibility factors for uveal melanoma include fair skin, light eye color, inability to tan, ocular or oculodermal melanocytosis, cutaneous or iris or choroidal nevus, and BRCA1-associated protein 1 mutation...

Cancer affects multiple organs in the body Malignant melanoma involves the invasion of skin and occasionally mucosal membrane or eye choroidal tissues. The incidence of cutaneous malignant melanoma is on the increase worldwide and is a major concern in current research. The increase is associated with UV irradiation-induced genetic aberrations that stimulate skin melanocytes to develop unlimited growth. This eventually leads to cell immortality, which in turn causes metastases. The present review examines the genetics and epigenetics of this pathological state together with recent perspectives of the therapeutic management of disease...

AIMS: Immunoglobulin G4 (IgG4)-related disease is known to have diverse clinical manifestations. We report a case of IgG4-related ophthalmic disease misdiagnosed as intraocular tumor. METHODS: Case report. RESULTS: A 41-year-old man was referred to our department with a diagnosis of intraocular tumor, presumably choroidal melanoma. Although MR imaging was compatible with choroidal melanoma, he had been observed periodically without treatment because fundus findings were not typical of melanoma and visual function was preserved...

A 56 year-old-male presented with diminution of vision in right eye of 2 months duration. His best corrected visual acuity (BCVA) was 20/25. Anterior segment examination was bilaterally normal. Right fundus revealed oval, raised, pigmented lesion in superotemporal quadrant with subfoveal fluid. Fundus fluroscein angiography (FFA) showed multiple pinpoint leakages. Acoustic hollowing on ultrasound (USG) was typical of choroidal melanoma. A high index of suspicion is required for the diagnosis of small choroidal melanoma that could present with multiple focal leaks and subretinal fluid simulating multifocal central serous retinopathy (CSR)...

There are several mimickers of choroidal melanoma. We report a patient with recent family stress who developed blurred vision to 20/50 OD and was found to have unilateral central serous chorioretinopathy and a coincidental choroidal nevus. After 1 year without resolution of the subretinal fluid, the patient was referred for our opinion. On examination, visual acuity was 20/50 in the right eye and 20/20 in the left eye. The left eye was normal. Evaluation of the right eye showed a small, pigmented submacular choroidal lesion measuring 4 mm × 3 mm...

REVIEW
Berçin Tarlan, Hayyam Kıratlı
Uveal melanoma, which is the most common primary intraocular malignancy in adults, arises from melanocytes within the iris, ciliary body and choroid. The diagnosis is based principally on clinical examination of the tumor with biomicroscopy and indirect ophthalmoscopy and confirmed by diagnostic techniques such as ultrasonography, fundus fluorescein angiography and optical coherence tomography. The clinical diagnosis of posterior uveal melanomas can be made when the classical appearance of a pigmented dome-shaped mass is detected on dilated fundus exam...
