Ota Nevus ni giza totoro la ngozi hasa karibu na eneo la neva ya trijemia, na kuathiri zaidi maeneo ya jicho yanayohudumiwa na mgawanyiko wa kwanza na wa pili wa neva hii. Hali hii, pia huitwa ocular dermal melanosis, husababisha kubadilika kwa rangi ya kijivu-bluu kutokana na melanositi zilizonaswa. Kawaida inaonekana upande mmoja wa uso na inaweza kuhusisha jicho, ngozi ya uso, na wakati mwingine paa la kinywa. Watu walio na hali hii wana uwezekano mkubwa wa kupata melanoma ya macho na glakoma. Nevus ya Ito ni sawa lakini huathiri maeneo tofauti ya neva.
Nevus of Ota is a benign melanosis that primarily involves the region of the trigeminal nerve distribution. The first and second divisions of the trigeminal nerve, namely the ophthalmic V1 and the maxillary V2 are most commonly involved. There is associated hyperpigmentation of the eye. Nevus of Ota is also known as ocular dermal melanosis. The characteristic gray-blue hyperpigmentation occurs due to entrapped melanocytes. Unilateral presentation is more common. The melanocytes are entrapped leading to gray-blue hyperpigmentation of the conjunctiva and sclera along with ipsilateral facial skin. There is an increased risk of uveal melanoma and glaucoma in these cases. Palatal involvement may also occur. Nevus of Ito is very similar to nevus of Ota except it differs in the territory of distribution. It was described by Minor Ota in 1954. It involves the distribution territory of lateral cutaneous brachial nerves of the shoulder and posterior supraclavicular nerves. Both of these diseases share similar pathophysiology.

Congenital dermal melanocytosis pia inajulikana kama eneo la Kimongolia. Ni aina ya kawaida ya alama ya kuzaliwa inayoonekana kwa watoto wachanga. Inaonekana kama mabaka ya kijivu-bluu kwenye ngozi tangu kuzaliwa au muda mfupi baadaye. Alama hizi kwa kawaida hupatikana kwenye sehemu ya chini ya mgongo na matako, huku mabega yakiwa sehemu inayofuata ya kawaida. Mara nyingi hutokea kwa watoto wachanga wa Asia na Weusi, na huathiri wavulana na wasichana kwa usawa. Kwa kawaida, hutoweka zenyewe wakiwa na umri wa miaka 1 hadi 6 na kwa ujumla hawahitaji matibabu yoyote kwani mara nyingi hawana madhara.
Congenital dermal melanocytosis, also known as Mongolian spot or slate gray nevus, is one of many frequently encountered newborn pigmented lesions. It is a type of dermal melanocytosis, which presents as gray-blue areas of discoloration from birth or shortly thereafter. Congenital dermal melanocytosis is most commonly located in the lumbar and sacral-gluteal region, followed by shoulders in frequency. They most commonly occur in Asian and Black patients, affect both genders equally, and commonly fade by age 1 to 6 years old. Congenital dermal melanocytoses are usually benign and do not require treatment.
