Ota nevushttps://en.wikipedia.org/wiki/Nevus_of_Ota
Ota nevus is 'n hiperpigmentasie wat op die gesig voorkom, wat meestal op die wit van die oog voorkom. Dit kom ook op die voorkop, neus, wang, periorbitale streek en tempel voor. Vroue is byna vyf keer meer geneig om aangetas te word as mans, en dit is skaars onder wit bevolking. Ota nevus mag nie aangebore wees nie, en kan na puberteit verskyn.
Daar is gerapporteer dat die gebruik van 'n Q-geskakelde 1064 nm laser suksesvol was in die behandeling van nevus van Ota.

Ota Nevus is 'n goedaardige verdonkering van die vel hoofsaaklik rondom die trigeminale senuwee-area, wat meestal die oogstreke beïnvloed wat deur die eerste en tweede afdelings van hierdie senuwee bedien word. Hierdie toestand, ook genoem okulêre dermale melanose, veroorsaak 'n grysblou verkleuring as gevolg van vasgevange melanosiete. Dit verskyn gewoonlik aan die een kant van die gesig en kan die oog, gesigvel en soms die dak van die mond betrek. Mense met hierdie toestand het 'n groter kans om oogmelanoom en gloukoom te ontwikkel. Nevus van Ito is soortgelyk, maar affekteer verskillende senuwee-areas.
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 staan ​​ook bekend as Mongoolse kol. Dit is 'n algemene tipe geboortevlek wat by pasgeborenes gesien word. Dit verskyn as grysblou kolle op die vel vanaf geboorte of kort daarna. Hierdie merke word tipies op die onderrug en boude gevind, met skouers wat die volgende algemene plek is. Hulle kom meer gereeld voor by Asiatiese en Swart babas, wat beide seuns en meisies ewe veel affekteer. Gewoonlik verdwyn hulle op hul eie teen die ouderdom van 1 tot 6 jaar en het gewoonlik geen behandeling nodig nie, aangesien hulle meestal onskadelik is.
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.
