Ota Nevus waa madoow aan fiicneyn oo maqaarka ku wareegsan gaar ahaan agagaarka neerfaha trigeminal, oo inta badan saameeya gobollada isha ee ay u adeegaan qaybaha koowaad iyo labaad ee neerfahan. Xaaladdan, oo sidoo kale loo yaqaanno melanosis maqaarka maqaarka, waxay sababtaa midab buluug-cawlan sababtoo ah melanocytes xanniban. Waxay badanaa ka soo baxdaa hal dhinac oo wejiga ah waxaana laga yaabaa inay ku lug yeelato isha, maqaarka wejiga, iyo mararka qaarkood saqafka afka. Dadka qaba xaaladdan waxay leeyihiin fursad sare oo ay ku qaadaan melanoma isha iyo glaucoma. Nevus of Ito waa la mid laakiin waxay saamaysaa aagagga neerfaha ee kala duwan.
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 sidoo kale waxaa loo yaqaan booska Mongolian. Waa nooc caan ah oo dhalashada lagu arko dhallaanka cusub. Waxay u muuqataa sida lakabyo cawl-buluug oo maqaarka ah laga bilaabo dhalashada ama wax yar ka dib. Calaamadahaan waxaa sida caadiga ah laga helaa dhabarka hoose iyo barida, iyadoo garbaha ay yihiin meesha xigta ee caadiga ah. Waxay aad ugu badan yihiin dhallaanka Aasiya iyo Madow, si isku mid ah ayey u saameeyaan wiilasha iyo gabdhaha. Caadi ahaan, waxay iskood u libdhaan markay da'doodu u dhaxayso 1 ilaa 6 sano, guud ahaanna uma baahna wax daawayn ah maadaama ay inta badan yihiin kuwo aan waxyeello lahayn.
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.
