ReferencesIs dorchú (hyperpigmentation) neamhurchóideach an chraiceann é Nevus of Ota (Ota Nevus) go príomha timpeall an limistéir nerv trigiméil, a théann i bhfeidhm go príomha ar réigiúin na súl a bhfreastalaíonn an chéad agus an dara rannán den nerv seo orthu. Is cúis leis an riocht seo, ar a dtugtar melanóis dermal súilíneach (ocular dermal melanosis) freisin, dídhathú liath‑ghorm (gray‑blue hyperpigmentation) de bharr melanocytes gafa (trapped melanocytes). De ghnáth bíonn sé le feiceáil ar thaobh amháin den aghaidh agus féadfaidh sé an tsúil, an craiceann aghaidhe, agus uaireanta díon an bhéil a bheith i gceist leis. Tá seans níos airde ag daoine a bhfuil an coinníoll seo acu uveal melanoma (melanoma súl) agus glaucoma a fhorbairt. Tá Nevus of Ito (Nevus of Ito) cosúil leis ach bíonn tionchar aige ar réimsí nerv éagsúla.
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, ar a dtugtar freisin mar láthair Mongóilis (Mongolian spot) nó neavú liath‑sliot (slate gray nevus). Is cineál coitianta de mharc breithe é a fheictear i nuabheirthe. Dealraíonn sé mar paistí liath‑gorm ar an gcraiceann ó bhreith nó go gairid ina dhiaidh sin. Faightear na marcanna seo go hiondúil ar an gcúl íochtair agus ar na masa, agus is iad na guaillí an chéad suíomh coitianta eile. Tarlaíonn siad níos minice i naíonáin na hÁise agus naíonán Dubha, rud a chuireann isteach ar bhuachaillí agus ar chailíní araon. De ghnáth, imíonn siad ina n‑aonar roimh 1 go 6 bliana d'aois agus go ginearálta ní bhíonn aon chóireáil ag teastáil uathu mar go bhfuil siad neamhdhíobhálach don chuid is mó.
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.
