Oculodermal melanocytosis (nevus of Ota) Contributor: Jesse Vislisel, MD Photographer: Brice Critser, CRA. Oculodermal melanocytosis, also known as nevus of Ota, is a condition of excessive pigmentation of the uvea, sclera, episclera, and eyelids secondary to an increase in the number of normal melanocytes Nevus of Ota also called oculodermal melanocytosis, is a pigmented birthmark that is slate-brown or blue/grey in color. Nevus of Ota is usually a unilateral, patchy dermal melanosis that affects the skin of the face along the distribution of the ophthalmic and maxillary divisions of the trigeminal nerve 1) Hyperpigmentation is when some patches of skin are darker than the surrounding skin. Nevus of Ota is also known as oculodermal melanocytosis. It's a type of dermal melanocytic hamartoma, which.. A blue nevus is a benign proliferation of melanocytes (which makes melanin pigment) in the dermis or skin that is generally bluish in appearance. The topic Oculodermal Melanocytosis you are seeking is a synonym, or alternative name, or is closely related to the medical condition Nevus of Ota
With concurrent hyperpigmentation of the periorbital skin, the term oculodermal melanocytosis is used. Recently, the term oculodermal melanocytosis has been utilized to combine the above two descriptions, as both entities involve the common denominator of ocular melanocytosis (Singh et al. 1998) Symptoms There are sometimes no noticeable symptoms of ocular melanoma, especially in the early stages. 1 In these instances, melanoma of the eye is usually diagnosed through a routine eye screening by an optician or ophthalmologist. Ocular melanoma symptoms include: Blurred vision in one ey In oculodermal melanocytosis, the skin pigmentation is usually unilateral; bilateral involvement is uncommon and is seen in approximately 5% of cases.13, 14 Ipsilateral scleral melanocytosis is found in approximately two thirds of cases.8, 11 In this study, the skin pigmentation was unilateral and the ipsilateral sclera was affected
In the early stage of uveal melanoma is asymptomatic and usually identified during routine eye check up. The following general sign and symptoms may influence individual to eye check up: Vision related problem or hazy vision Experience of floaters means in the vision field feeling of dusty spots or light also flash with periodic interval Signs and symptoms of intraocular melanoma include trouble seeing or a dark spot on the iris. These and other signs and symptoms may be caused by intraocular melanoma or by other conditions. Check with your child's doctor if your child has any of the following Oculodermal melanocytosis (nevus of Ota) is a benign, congenital, melanocytic pigmentary disorder, most commonly involving the area innervated by the first and second divisions of the trigeminal nerve. We describe a case of cutaneous melanoma that developed in a nevus of Ota. CASE REPOR Symptoms People with choroidal or ciliary body melanoma may not have any symptoms and the tumor might be detected during routine examination. Symptoms may include decreased or blurry vision. Patients with iris melanoma may notice a dark spot on the colored part of the eye or a distorted pupil
The aim of this study was to determine the prevalence of ocular and oculodermal melanocytosis (ODM) among patients with uveal melanoma (UM) in a Spanish population. Retrospective review of the.

— Ocular or oculodermal melanocytosis (pigmentation of the eye or skin around the eye; it also represents called nevus of Ota) — Nevi, or places like moles in the eye — Dysplastic nevus syndrome (a condition commemorated by several flat moles that are irregular in shape or dye These factors include thickness greater than 2 mm, related subretinal fluid, symptoms, overlying orange pigment (lipofuscin), tumor margin within 3 mm of the optic disc, ultrasonographic hollowness, absence of surrounding halo, and absence of overlying chronic drusen. 9 Our patient displayed 6 of 8 risk factors, implying high likelihood for further growth of the lesion into a larger melanoma The risk in ocular or oculodermal melanocytosis is quite high, with a lifetime risk of approximately 1 in 400. Although choroidal nevi may become melanomas, it is still very rare, with approximately 1 in 5000 nevi developing into melanomas per year Ocular melanocytosis or oculodermal melanocytosis and sector iris hamartoma can also cause hyperpigmented irides. Congenital and acquired hypopigmented irides can occur because of Horner's syndrome, Fuchs heterochromia, Waardenburg-Klein syndrome, nonpigmented iris tumors, and hypomelanosis of Ito. Symptoms
The diagnosis of dermal melanocytosis is usually made by observing typical discolouration of the skin. It is classified according to the site affected. Some patients may undergo skin biopsy, which confirms the presence of melanocytes in the dermis. Other skin conditions resulting in bluish or grey coloured skin may be considered NCI's Dictionary of Cancer Terms provides easy-to-understand definitions for words and phrases related to cancer and medicine Children with oculodermal melanocytosis should be examined periodically because of a risk of pigmentary glaucoma and melanoma . Patients with ocular melanosis may also benefit from surveillance of the intraocular pressure . Some children with oculodermal melanocytosis may have pigmented lesions on the tongue and buccal mucosa
Abnormal brown spots on the uvea (oculodermal melanocytosis or nevus of ota) Bap1 cancer syndrome ; Moles in the eye or on the skin ; Family history (rare) Unproven risk factors. Sun exposure: a known risk factor for melanoma of the skin, it may be a possible risk factor for uveal or conjunctival melanoma of the eye, but more research is neede The nevus of Ota (oculodermal melanocytosis, naevus fusculocoeruleus ophthalmomaxillaris) was described by the Japanese dermatologist, Ota, in 1939. It is a light bluish nevus on the unilateral face, which is congenital or acquired in adolescents. It has been shown to be more common in East Asians (0.2-1.0%) than in western populations (0.04%) 5 Blue sclera. Blue sclera is caused by thinness and transparency of the collagen fibers of the sclera that allow visualization of the underlying uvea (Figure 1). The sclera is the white outer coat of the eye, surrounding the iris may be thinned in congenital diseases such as osteogenesis imperfecta 1). Other diseases associated with blue sclera.

We report on a 45-year-old Caucasian woman with a nevus of Ota that presented with visual disturbances involving her right eye and was found to have a biopsy-proven cellular blue nevus in the orbital space. Five years later, she presented with proptosis and worsening symptoms. Biopsy at that time showed a cellular blue nevus with areas of melanoma . However on page 87, a description of the same condition mentions that patients with oculodermal melanocytosis are at increased risk of glaucoma, and on page 116, oculodermal melanocytosis is within a table as a cause of infantile glaucoma
Nevus of Ota (oculodermal melanocytosis) is characterized by benign melanosis involving the skin of the face about the eye, which is supplied by ophthalmic and maxillary divisions of the. Oculodermal melanocytosis (ODM), also known as naevus of Ota, is a rare disease characterized by slate-grey hyperpigmentation of the facial area sup-plied by the ophthalmic and maxillary division of trigeminal nerve as well as some ocular structures.1 The discoloration could also be brown or blue. I Oculodermal Melanocytosis-If a person has this disorder, it leads to elevated and abnormal pigmentation of the eye or the skin near the eye. He is more at risk of developing this disease. He is more at risk of developing this disease
Tumors are located either in iris (4%), ciliary body (6%), or choroid (90%). Other susceptability factors for uveal melanoma include inability to tan, ocular or oculodermal melanocytosis, cutaneous or iris or choroidal nevus, use of sunbeds and BRCA1-associated protein 1 mutation Neoplasm Meningeal Melanocytoma of the Brain and Oculodermal Melanocytosis (Nevus of Ota): Case Report and Literature Review Vafa Rahimi-Movaghar, M.D.,* and Mehrbod Karimi, M.D.† *Department of Neurosurgery, †Department of Pathology, Khatam-ol-anbia Hospital, Zahedan University of Medical Sciences, Zahedan, Iran Rahimi-Movaghar V, Karimi M.

Family history Ocular or oculodermal melanocytosis: This is a pigmentation of the eye or skin around the eye; Nevi: Nevi are spots or moles in the eye. Dysplastic nevus syndrome: This condition produces multiple flat moles that are irregular in shape or color. Family history: Intraocular melanoma can run in families, although it is rare (J Am Acad Dermatol 1998;38:862-5.) Oculodermal melanocytosis (nevus of Ota) is a benign, congenital, melanocytic pigmentary disor- der, most commonly involving the area innervated by the first and second divisions of the trigeminal nerve. We describe a case of cutaneous melanoma that developed in a nevus of Ota
Naevus of Ota is on the forehead and face around the eye area. Hyperpigmentation of parts of the eye may occur ( sclera, cornea, iris, retina) Naevus of Hori is similar to naevus of Ota but affects both sides of the face. Naevus of Ito is on the shoulder and upper arm area (shoulder girdle). Dermal melanocytosis can also occur elsewhere on the. Sclera Definition: White of The Eyeball. The sclera is commonly known as the white of the eye. It surrounds your entire eyeball, except for the cornea (the clear covering in the front of your eye). The cornea is continuous with the sclera. The area where the sclera meets the cornea is called the limbus. The sclera forms more than 80 percent of. .
Oculodermal melanocytosis is a rare condition more frequently encountered in the Asian population with a prevalence of 0.014%-0.034% . Glaucoma is found in about 10% of patients and the pathogenesis may be congenital, developmental or associated with the diffuse characteristic oculodermal hyperpigmentation of the disease which leads to.

Abnormal brown spots on the uvea (oculodermal melanocytosis or nevus of Ota) The doctor will ask you about your health history, symptoms, risk factors, and family history of disease. He or she will do an eye exam. During the eye exam, the doctor will use a special scope with a light (ophthalmoscope) to look at the inside of your eye Congenital ocular melanocytosis is a rare anomaly that requires regular follow-up, since it carries an increased risk of glaucoma and uveal malignant melanoma. Idiopathic intracranial hypertension (IIH) has several identifiable risk factors in children. We report a previously unrecognised association between the two conditions in a child. A 5-year-old Caucasian girl was under regular follow-up.
The causes of OM development remain poorly understood. Notwithstanding, individual risk factors have been identified: Patients with congenital ocular or oculodermal melanocytosis have a lifetime risk of 1 in 400 to develop uveal melanoma . Similarly, uveal nevi, particularly large ones, augment the risk of this type of cancer Abstract : In this study, we report a rare case of choroidal melanoma melanoma Subject Category: Diseases, Disorders, and Symptoms see more details in an eye with oculodermal melanocytosis (Nevus of Ota).

Patients found to have a mole under the retina should have a dilated eye exam every six to 12 months to monitor the condition. Those with symptoms or high-risk features should be referred to an ocular oncology specialist for further evaluation. To connect with Dr. Walter or the Hartford HealthCare Melanoma and Skin Cancer Center call 860.524.2723 . This theory is based on altered vasomotor regulation, which leads to the formation of phakomas and the naevus flammeus [104, 115] Oculodermal melanocytosis is a congenital disorder resulting from defective neural crest cell-derived melanocyte migration. These lesions typically appear on the facial skin and globe. The episclera often has bluish, fusiform spots underlying normal conjunctiva. These lesions are usually unilateral, but occasionally are bilateral
Symptoms. The Nevus of Ota appears as increased pigmentation of one eye and its eyelids. The eyelid is darkened, pigment can be observed on the white of the eye and that iris may be darker (compared to the contralateral iris). Though none of these findings produces physical symptoms, physical asymmetry can have a psychological impact on the.

A propensity to sunburn is another. Others are rare genetic conditions and ocular/oculodermal melanocytosis, a condition with a lifetime risk of approximately one in 400 of developing uveal. Nevus of Ota (nevus fuscoceruleus ophthalmomaxillaris, oculodermal melanocytosis) Bluish hyperpigmentation of the skin along the ophthalmic and maxillary branches of the trigeminal nerve is known as Nevus of Ota . These patches can be brown, blue-gray or blue-black, gray or purple and have a speckled or mottled appearance with poorly-demarcated.
Higher rate in those with preexisting choroidal nevus and congenital ocular/oculodermal melanocytosis (1/400 risk) Middle aged men and women Can be asymptomatic or symptomatic (photopsia, floaters, visual field loss, secondary glaucoma When symptoms develop, the patient notes persistent photopsia (flashes), floaters, or visual loss. Rarely, larger Fig. 1 Oculodermal melanocytosis. A, There is iris heterochromia (darker iris left eye). Note scleral melanocytosis B, superiorly and C, inferiorly. This eye is at risk for uveal melanoma Macular telangiectasia (Mac Tel) leads to abnormalities of capillaries of the fovea or perifoveal region associated with loss outer nuclear layers and ellipsoid zone that can progress to cystic cavitation-like changes in all retinal layers, or development of full-thickness macular hole or subretinal neovascularization in advanced stages Oculodermal melanocytosis occurs mostoften in orientals andblacks andis rarely seenin the white population.25-7 In contrast, malignant melanoma transformation associated with ODM and OM is known to occur more often in whites and rarely amongblacks and orientals.5 7-9 The rarity of black patients reported with ODMandchoroidal melanom

Congenital ocular melanocytosis only involving the skin: _ _ Signs/symptoms of necrotizing anterior scleritis without inflammation: No inflammation or pain Initial sign= yellow necrotic scleral patch Thinning, melting, and loss of sclera due to. Eye Cancer Symptoms. Eye cancer rarely causes symptoms in early stages of the disease. It usually starts in parts of the eye you cannot see. Often, eye doctors find eye cancer during regular exams before symptoms develop. When symptoms develop, the most common one is painless vision loss. Other signs and symptoms of eye cancer include: Blurry.
Caucasian patients who have congenital ocular or oculodermal melanocytosis (nevus of Ota) are especially at risk to develop uveal malignant melanoma. 40 It has been estimated that about one in 400 white patients with oculodermal melanocytosis will develop uveal melanoma in his or her lifetime. 41 This risk is about 25 times greater than the. Individuals with brown spots over the uvea in a condition called oculodermal melanocytosis are at a higher risk of eye melanomas as well. Eye melanomas may also be inherited and may run in some. Benign cutaneous pigmented lesions may result from an increased production of melanin or a proliferation of melanocytes. In ephelides, café-au-lait macules (CALMs), Becker melanosis, and lentigines, there is an increase in melanin production by melanocytes followed by its transfer to keratinocytes. When multiple CALMs are present, the. developing UM (19). Oculodermal melanocytosis, also known as Nevus of Ota, represents a relevant risk factor for developing UM (20,21). This condition is characterized by an abnormal congenital hyper‑pigmentation within the V1/V2 trigeminal nerve area, and can involve periocular skin, orbit, uvea, scler Of importance in patients presenting with rash-like symptoms is the recognition of atopy (as manifest by hay fever or asthma) as this history is suggestive of atopic dermatitis. point to specific diagnoses such as Herpes infection or oculodermal melanocytosis
Ocular and oculodermal melanocytosis (Nevus of Ota), dysplastic nevi and cutaneous melanoma are correlated with an increased risk of UM development (Carreno et al, Presence of symptoms, as mentioned earlier or a change in symptoms is a risk factor for malignancy. Orange pigment is formed on melanomas of the posterior pole, although this can. Pseudoxanthoma elasticum (PXE) is a rare genetic disease characterized by elastorrhexia, or progressive calcification and fragmentation, of elastic fibers primarily affecting the skin, retina, and the cardiovascular system.   [3 Oculodermal melanocytosis. Presence of cutaneous nevi. In a European Oncology Group study, 57% of children were females and four had a preexisting condition that included oculodermal melanocytosis (n = 2) and neurofibromatosis (n = 2) Other risk factors include ocular melanocytic conditions such as oculodermal melanocytosis (nevus of Ota) and melanosis oculi. Choroidal nevus, a common benign tumor found on the fundus, may rarely transform to melanoma. Patients often present without any symptoms, and the choroidal melanoma is found incidentally on routine eye examinations
