Ocular cytology specimens are relatively uncommon, adding to the difficulty of their evaluation by cytopathologists. While melanomas account for a majority of primary intraocular pigmented lesions, other diagnostic considerations must be included in the differential. This brief report highlights a case of a pigmented ocular lesion in a 24-year-old man and key morphologic, immunohistochemical, and clinical differences between melanoma, melanocytoma, choroidal nevus, and retinal pigment epithelium (RPE) adenoma...

Bcl-2-associated athanogene 3 (BAG3), a co-chaperone of heat shock protein 70 (HSP70), exerts anti-apoptotic effects in various malignant tumors. However, relationships between choroidal melanoma and BAG3 are poorly studied. This study investigated the expression of BAG3 in a case of human choroidal melanoma. Funduscopy, computed tomography, and single-photon emission computed tomography with the intravenous injection of N-isopropyl-p-[(123)I] iodoamphetamine strongly indicated choroidal melanoma in a 68-year-old woman...

PURPOSE: Birt-Hogg-Dubé Syndrome (BHDS) is a rare autosomal dominant condition that can predispose patients to numerous cutaneous fibrofolliculomas and other cutaneous lesions, pulmonary cysts with spontaneous pneumothorax, and multifocal renal tumors and cancer. The genetic mutations responsible for BHDS are related to tumor suppression and the mammalian target of rapamycin (mTOR) pathway. Previous reports of the ocular findings in BHDS include eyelid fibrofolliculomas, "flecked chorioretinopathy," and one report of choroidal melanoma...

PURPOSE: To report a case of "posterior scleral melanocytosis," a pigmented lesion of the posterior sclera that clinically resembles a flat choroidal nevus. METHODS: Case report of a patient with posterior scleral melanocytosis. Multimodal imaging, including swept source optical coherence tomography, was used to demonstrate the scleral location of the pigmented lesion and to distinguish its features from a typical choroidal nevus present in the same eye. RESULTS: An 86-year-old woman was seen for regular follow-up for neovascular age-related macular degeneration in her right eye and 2 pigmented lesions in her left eye, both presumed to be choroidal nevi...

We present a case of choroidal nevus, complicated by a choroidal neovascular membrane (CNV) that was detected by OCT angiography. Choroidal nevi are relatively common intraocular tumors. The presence of subretinal and intraretinal fluids can indicate that a CNV has occurred as a complication, warranting prompt management. However, subretinal and intraretinal fluids are also documented in nevi without CNV. OCT angiography may be of great help in determining whether those fluids are associated or not with a CNV, therefore guiding therapy...

We report a case of a Caucasian female who developed active polypoidal choroidal vasculopathy (PCV) at the edge of a stable choroidal nevus and was successfully treated with verteporfin photodynamic therapy. No active polyp was detectable on indocyanine green angiography 2 years after treatment, and good vision was maintained. Indocyanine green angiography is a useful investigation to diagnose PCV and may be underutilized. Unlike treatment of choroidal neovascularization secondary to choroidal nevus, management of PCV secondary to nevus may not require intravitreal anti-vascular endothelial growth factor therapy...

Retinitis Pigmentosa (RP) has been reported to be associated with retinal hemangioma, retinal angiomatous proliferation, polypoidal choroidal vasculopathy and vasoproliferative tumours. However there is no previous report of choroidal nevus in an eye with RP. We describe such a case in which the eye with RP had a choroidal nevus at the macula. The coexistence of these two entities in the same eye emphasizes the need of careful examination of patients with RP. The presence of choroidal nevus warrants additional investigations such as B scan ultrasonography and a close follow-up to pick up changes in the nevus size and morphology...

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...

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...

Importance: Although mostly asymptomatic, patients with choroidal nevi carry a moderate risk for malignant transformation and visual loss. A novel noninvasive imaging assessment could change the current clinical evaluation of choroidal nevi. Observation: Three patients with a recent diagnosis of choroidal nevi underwent a novel adaptive optical assessment that detected potential photoreceptor abnormalities in the retina overlying the choroidal nevi. Conclusions and Relevance: Adaptive optics imaging may provide high-resolution en face images of retinal structural changes in the photoreceptor mosaic overlying the choroidal nevi...
