ReferencesOta Nevus — гэта добракаснае пацямненне скуры, якое звычайна размяшчаецца вакол вобласці трайніковага нерва і закранае ўчасткі вачэй, інэрвуюемыя першым і другім аддзеламі гэтага нерва. Гэта захворванне, якое таксама называюць вочным дермальным меланозам, выклікае шэра-блакітны колер з-за назапашвання меланацытаў. Звычайна яно праяўляецца на адным баку твару і можа ахопліваць вока, скуру твару, а часам і навакольныя структуры. Людзі з гэтым захворваннем маюць павышаны рызыка развіцця меланомы вачэй і глаўкомы. Невус Іта падобны, але закранае іншыя нервовыя вобласці.
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, таксама вядомы як мангольская пляма, — распаўсюджаны тып родных плям, якія сустракаюцца ў нованароджаных. Ён з'яўляецца ў выглядзе шэра-блакітных плям на скуры з нараджэння або неўзабаве пасля. Гэтыя сляды звычайна размяшчаюцца на ніжняй частцы спіны і ягадзіцах, а плечы — яшчэ распаўсюджанае месца. Яны часцей сустракаюцца ў азіяцкіх і чарнаскурых дзяцей, у аднолькавай ступені ў хлопчыкаў і дзяўчынак. Звычайна яны знікаюць самі па сабе ў ўзросце ад 1 да 6 гадоў і, як правіла, не патрабуюць лячэння, бо з'яўляюцца бясшкоднымі.
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.
