Ota Nevus ir labdabīgs ādas tumšums, galvenokārt ap trīszaru nerva zonu, galvenokārt skarot acs reģionus, kurus apkalpo šī nerva pirmā un otrā nodaļa. Šis stāvoklis, ko sauc arī par acs dermas melanozi, izraisa pelēkzilas krāsas maiņu iesprostoto melanocītu dēļ. Tas parasti parādās vienā sejas pusē un var ietvert acis, sejas ādu un dažreiz arī mutes jumtu. Cilvēkiem ar šo stāvokli ir lielāka iespēja saslimt ar acs melanomu un glaukomu. Ito nevus ir līdzīgs, bet ietekmē dažādas nervu zonas.
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 ir pazīstams arī kā Mongoļu plankums. Tas ir izplatīts dzimumzīmes veids, kas novērots jaundzimušajiem. Tas parādās kā pelēkzili plankumi uz ādas kopš dzimšanas vai neilgi pēc tam. Šīs zīmes parasti atrodas muguras lejasdaļā un sēžamvietā, un pleci ir nākamā izplatītā vieta. Tie ir biežāk sastopami Āzijas un melnādainiem zīdaiņiem, vienādi ietekmējot gan zēnus, gan meitenes. Parasti tie izzūd paši no 1 līdz 6 gadu vecumam, un parasti tiem nav nepieciešama nekāda ārstēšana, jo tie lielākoties ir nekaitīgi.
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.
