ReferencesNevus fan Ota (Nevus of Ota) is in goedaardige melanosis (benign melanosis) fan de hûd, benammen yn it trigeminale senuwgebiet, meast op it wite fan it each en troch de earste en twadde divisjes fan dizze nerv. Dizze betingst, ek wol okulêre dermale melanosis neamd, feroarsaket in griis‑blauwe hyperpigmentaasje (gray‑blue hyperpigmentation) troch ynsletten melanocyten. It ferskynt meast unilateraal oan it gesicht en kin de konjunktiva (conjunctiva), de sclera en soms it palatum (palate) belûke. Minsken mei dizze betingst hawwe in hegere kâns op it ûntwikkeljen fan uveale melanom (uveal melanoma) en glaukom (glaucoma). Nevus fan Ito (Nevus of Ito) is fergelykber, mar hat ynfloed op ferskate nervegebieten.
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 is ek bekend as Mongoolsk flek (Mongolian spot). It is in gewoan type bertemerk sjoen yn pasgeborenen. It ferskynt as griis-blauwe plakken op 'e hûd fan berte of koart dêrnei. Dizze merken wurde typysk fûn op 'e legere rêch en billen, mei skouders as de folgjende mienskiplike lokaasje. Se binne faker yn Aziatyske en Swarte berntsjes, en beynfloedzje sawol jonges as famkes gelyk. Gewoanlik ferdwine se op harsels op 'e leeftyd fan 1 oant 6 jier en hawwe oer it algemien gjin behanneling nedich, om't se meast harmless binne.
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.
