Melanoma is a type of cancer that develops in the cells that produce melanin — the pigment that gives your skin its color. Your eyes also have melanin-producing cells and can develop melanoma. Eye melanoma is also called ocular melanoma. Most eye melanomas form in the part of the eye you can't see when looking in a mirror Scleral melanocytosis is a common pediatric condition that becomes prominent with increasing age and usually is bilateral. The benign condition is more common in persons of Asian descent. 1. The condition characteristically features black or gray-blue pigmentation in the scleral tissue. Histologic examination shows dendritic melanocytes in the. . The nevus is located in the deep episclera, sclera and uveal tract and can manifest clinically as iris heterochromia, patchy slate-gray or bluish discoloration of the sclera, and increased pigmentation of the ipsilateral fundus Primary Acquired Melanosis: unusually large numbers of melanocytes develop. This is rare in dark-skinned races and tends to affect older white-skinned people. Congenital Melanocytosis: similar, except present from birth. A Naevus, that is a brown spot on the conjunctiva, may be present from birth or may arise later
Dear ntilley, I would recommend that you take your daughter to a pediatric eyeMD to determine the appropriate diagnosis and obtain immediate medical care.

Most melanomas of the eye develop in the uvea — the middle layer of the eyeball. Caucasians are at much higher risk for. Eye melanoma usually begins in the middle layer of the eye known as the uvea. This is the layer in which the blood vessels travel through the eye. The outer layer is the sclera (the thick white part) and the inner layer is the retina (where the rods and cones that are the sensory part of the eye pick up signals to send to the brain.
If multiple spots develop and coalesce (run together), the condition is called diffuse iris melanosis. Early in its course, iris melanosis is a benign condition. If the pigmentation steadily progresses, however, it may become a form of malignant mel-anoma. Although freckles and nevi may occur in one or both eyes, the diffuse form of the disease typically affects only one eye It is a conjunctival lesion involving only one eye that is usually accompanied by a slate grey colored patch in the skin near the affected eye. Benign Melanosis, also called racial melanosis, typically involves both eyes and looks like patchy areas of increased pigmentation in the white part of the eye. It is common among middle-aged people. A benign appearing choroidal nevus (eye freckle). Like a raised freckle on the skin, nevi can also occur inside your eye. The most common choroidal nevus or eye nevus are unusual and can only be seen by an eye care specialist. Like a nevus on the skin, a choroidal nevus can grow into a malignant melanoma Ocular melanoma (OM for short) is a cancer of the eye diagnosed in approximately 2,000-2,500 adults annually in the United States. In both the U.S. and Europe, this equates to about 5 - 7.5 cases per million people per year and, for people over 50 years old, the incidence rate increases to around 21 per million per year
Often melanomas of the eye are found during a routine eye exam. When the doctor looks through the pupil at the back of the eye, he or she may see a dark spot that might be an early melanoma. Many doctors feel that most melanomas start from a nevus (mole), which is a benign (non-cancerous) tumor of pigment cells A conjunctival nevus is a pigmented lesion on the white part of the eye, known as the conjunctiva. If a nevus does need to be removed due to any complications, melanoma, or suspicion of.

Ocular melanomas can originate from the uvea or the limbus. About 80% of uveal melanomas (and all limbal melanomas) are benign. The rate of metastasis is less than 5%. Ocular melanomas are at least in part heritable and caused by one or more genetic mutations. Uveal melanomas can become discrete, raised pigmented masses.
Melanosis coli is a condition usually associated with chronic laxative use in which dark pigment is deposited in the lamina propria (one of the lining layers) of the large intestine (colon). The pigment deposition results in a characteristic dark brown to black discoloration of the lining of the large intestine In the early stages of eye melanoma in dogs, it appears to be an iris freckle, an obvious spot which usually does not disturbs the anatomy and thickness of the iris, but may be a single freckle or many freckles and is either unilateral (in one eye) or bilateral (both dog eyes).

Choroidal nevi are slate-gray and relatively flat (less than 2mm thickness), although there is significant size overlap between small melanomas and larger nevi. Like choroidalal melanomas (i.e. full-blown eye cancers), they also may show overlying drusen or lipofuscin (figure 2). A nevus almost never causes any symptoms The Blue Mountains Eye Study recorded choroidal nevi in 6.5 percent of a prospectively studied population of mostly middle-aged white Australians.1 Choroidal melanomas, on the other hand, are fortunately a rare entity, with an estimated incidence of approximately six per million.

Another type of ocular melanoma in cats is the limbal (sometimes called epibulbar) melanoma. Limbal melanomas develop from the melanocytes found at the limbus, the border of the cornea (transparent front part of the eye), and the sclera (white part of the eye). Limbal melanomas are benign (non-cancerous) and less common than iris melanomas
Choroidal Melanoma. A choroidal melanoma is a malignant tumor of the retina. It may spread (metastasize) to other parts of the body and can be fatal.

The sclera is the white part of the eye that surrounds the cornea.In fact, the sclera forms more than 80 percent of the surface area of the eyeball, extending from the cornea all the way to the optic nerve, which exits the back of the eye.Only a small portion of the anterior sclera is visible White Spots on Skin. A common complaint is the appearance of white spots on skin. Potential causes include: Vitiglio: Skin condition where the skin loses pigment or color.

An athletes foot or jock itch cream could be of some help Although there are other reasons cats develop spots and splotches in their eyes - including trauma to the cornea and certain viruses - those tell-tale pigment changes in the iris often indicate melanosis. Veterinarians classify the flat, benign tumors as melanocytomas and the raised metastatic or diffuse spots as melanomas
The presence of melanosis or melanoma within the pouches indicates that multiple areas may be affected and the treatment plan may have to be radically altered.
